View Full Version : I said it first: It's too heavy

I was the first to post a thread for the new 2007 GT500 post when the car was first released. I said it then, first, and I was validated by the latest Car and Driver comparo with a Z51 C6 Corvette.

I said then that the new GT500 would be nothing more than an "image" car with gobs of horsepower. Sure enough, with 100 more hp than the Vette, the new GT500 was outdone by the C6 because the new Snake is too damn heavy. I said then that the car would be 3800+ pounds. Well, it's 3900 with bad forward weight bias, and that turned out to be the Achille's heel for the car. Granted, it posted good numbers, but 500 horsepower and fat tires will do that. The article did note that the acceleration was very similar to the "Terminator" Cobras. This I like since I have one! :thumbsup:

I'm not a fan to the new GT500, but don't get me wrong, I think it's a great car and I do like its look. I just won't be buying one. I'm very performance oriented and the Corvette Z06 has won me over. Hell, I'll take a Z51 over the GT500 if I can't afford the Z06.

In short, I was disappointed when the car came out, and I'm disappointed still that the car turned out to be more of a lead-sled with a solid axle, instead of a real road racing beast. At over $40K, you'd think Ford/SVT could have done more.

Come on guys, I thought for sure there'd be a ton of replies to this thread. I know some are die-hard GT500 fans, others aren't at all. Oh well, I guess everyone is out buying the latest issue of Car & Driver to see what the heck I'm talking about. :p

I await your thoughts... :D

The only thing I would say is that for a small amount of money spent on a pulley swap I would think you should have no problem handling those corvettes. I haven't done much research on the new "cobra". I would assume that it would be more mod friendly? I rode in a friend's 06 corvette and it was very nice but it wasn't like my Terminator. I really liked the interior of the corvette and it looks cool on the street. I'm sure the new Z06 is alot faster but they sure are very expensive. The dealers around here are getting $20,000 over sticker. I'm going to get a kenne bell soon to make sure that I can handle a new ZO6 if I run into one.

Yep, I would agree it is too heavy and would probably be not much of an effort to whip one on the track if the driver is inexperienced. Seems that Ford dropped the rear gear down to a 3.31 as well as changed the ratio for first gear in the transmission to 2.97:1. MM&FF had an article on the Shelby and the quarter mile times were at best 12.257 / 117.18mph with a professional driver and the best I have done in my 04 Cobra was 12.597 / 110mph without any mods except for a cat back (considering I am novice at drag racing). That will not stop me from going to the track and racing even if the GT500 can terminate a terminator. In my opinion, the package under the bonnet in the 99 to 04 Cobras has more appeal than what was shown under the hood of the GT500.

Wonder when the owners of the GT500's will be ripping out the Eaton M122's for something a bit more potent. Then it would be interesting to see if the M122 would fit a 4.6L powerplant since that is close to the whipple and KB 2.2L blowers.. Sooner or later there may be a M122 conversion write up for us M112 owners. It probably will not fit unless the rear inlet can be interchanged with the one from the M112.

im so sick and tired of hearing about this big fat pig of a car.look yesterday i received my monthly issue of mmff and i open it up to read the article on this ride and hear at the top of the article it says (will terminate a terminator)pleeease i cant wait to run into one on the road and smoke their ass.it just seems to me that mmff now finds it okay to down play the terminators now because of this car with shelbys name.2 months ago the terminator was unstoppbable now they make like its a sissy compared to the shelby.i mean what the shelby pulled out 12.2 the cobra 12.6 with a convertible to me that is not termination thats a disgrace on shelbys part.for that kind of money they want and the type of hp it puts out it should be turnin 11's right out of the box so needless to say im not impressed by no means im so tired of seeing carol shelbys fat butt in this magazine grinning as if he just put this car together by hand himself he is such a s***bag.hes so old he really should be standin next to a vette instead.and im sure he would if they gave him the right amount of money.hes such a sellout!:mad:

Dang Wes, Why don't you tell us how you truly feel! :rotf:

I agree with you about wanting to see the face on some of these 07 Shelby owners. There they'll be sitting in a garage, looking pristine, unmodded for originality because it's an investment. Meanwhile, on the street and strip, many of us will have our modded 03/04's with 525 rwhp plus just eating them up making some of them look silly. Like you, I hope I'll get to see one on the street, they'll be stylin, while looking at my "COBRA" bumper cover. :)

:thumbsup: They don't call them terminators for nothing. There is more to the 03/04 Cobras than what meets the eye of MM&FF. Actually the article did not seem very impressive at all and basically the statement was there for hype. Poetic injustice. They better but the money on the table if they are going to make that cliam. Would be nice to see a heads up challenge between the 03/04 cobra and the GT500 in stock trim including the tires (out of the box).

Sorry boys, Ford had no intention of making this car a Mean Street Machine, but rather a Road Trophy. Ford wanted to make this a combination of Style, Flair, and a little bit of Horsepower, rather than a fire breathing demon bat out of hell car. Take a Mustang GT Body, put on some style, add a little hp, and a whole lot of weight, and Carol Shelby's name, and you get the 07 GT500. This car will be owned by people wanting a road trophy, not a performance machine. To me this is just another 69 Camaro with a slightly souped up 350 under the hood.

I mean come on...a 330 cubic inch motor w/a supercharger? 3.31 rear gear ratio's? 12.2 second quarter mile? Bleh. So far the only thing on this car that I see as impressive is the 0-60 mph time which is 4.5. No it's not the fastest, but it is landmark 0-60 for a factory mustang.

If Ford really wanted to compete with a Z06 Vette or even better yet a Viper..they could have done it, and here's how.

The current exterior cosmetics is great, they can leave that alone. (except for the raised hood vents should have been inset hood vents).
The powerplant should have been a 429 cubic inch motor
Iron Block
Heads Ported and Polished to the max!
HiPo Camshaft
Fuel Injected of course
Roots Style Supercharger
3.73 rear gear ratio
8.5 or 9.0:1 compression ratio
NO A/C, CD Player, Radio, Etc.
No Glove Compartment, side door storage areas, etc.
Factory Underdrive Pulley's already installed
Cold Air Kit already installed
Performance Chip already installed and set to the max
No Speed Limiter
No Rev Limiter
No rear seats
No spare tire
Should have had the IRS Suspension
700 Hp or more
Target Vehicle Weight Should have been around 3100-3400 pounds.
46% front weight to 54% rear weight, or even 50/50 if it's done right.

A car like this would be capable of speeds near or at 200 mph, and quarter speeds in the 10's for sure. Hell, a car like this might take a damn Porsche or Mercedes.

Yeah, there would have been a massive gas guzzler tax on the damn thing, but you talk about some awesome power, and something that would smoke any Vette or Viper without a moments hesitation! This would have been a striped-a$$ monkey running machine, and would probably get down in the low to mid 10's. This is what Ford should have done if they only had the stones to do it.

I'm not impressed with the numbers and the overall capability of this LATE MODEL SHELBY either.
Marginally better performance considering the chassis limitations and what could have been .... :rolleyes: but, that's for another discussion.
Would I choose a Stage3 over it if I were in the market? Probably.

The HYPE is funny because when it fades there will be SHELBYs sitting on the lots with incentives this time next year.

The new Shelby is just a cobra built by SVT like ours but with a sticker or two that says Shelby on it. Thats all Shelby has to do with the car. I think that since the new Shelby car that wasn't developed and tested by Shelby himself like the 1960s were won't be worth any more than they are now in the future. This new car will be just like the Dodge Shelby Chargers of the 80s http://www.xmission.com/~dempsey/shelby/sheldod1.htm

you guys need to drive the new shelby before you criticize it so much. i have had mine for about 2 weeks and i like it more each time i drive it. i dont care what the magazines say, it is faster than a c6 corvette. i just sold a porsche 911 turbo stage 4 with 560 horsepower and the shelby isnt as fast as the porsche, but its not far off. it drives great, ride and handling, so give it a chance, dont just go by what other people say;)

I would agree that driving it would make a difference in opinion. The new body style of the car is beginnig to grow on me, every time I see a new one they can be very sharp depending on what was done to the exterior as far as cosmetics are concerned. As for the Shelby GT 500, the first one I saw in person was at the 30th annual First PA mustang club car show on August 20th this year. I guess I would be happy if I had one. Looks really good as it is :thumbsup: Too bad the owner did not leave the hood up to show the engine (that would have been nice to view the power plant other than in pictures on the net).

I haven't driven the new Shelby (John Coletti's SVT Cobra by my standards) but if it has 490 rwhp then I'm sure I'd like it. If it plants me in the seat then I like it, if it outruns a C6 Vette then I like it. (but why aren't you comparing it to a new Z06? :doubt: ) My biggest beef is not the car itself but the fact that the Blue Oval dumped us SVT owners for a freaking marketing ploy. That car should have been the next SVT Cobra, not a Shelby, not a GT, not anything else but an SVT Cobra so you'll have to pardon my attitude about the car. I feel like the SVT Cobra owners were left out in the cold just so people can say "I just bought one and I own a Shelby". They don't own a Shelby, they own an SVT Cobra, so we have to deal with "don't knock it till you tried it". Your car has an SVT snake on it, SVT wheels, SVT powertrain, SVT on the sills and instrument cluster. So there's my personal beef with the car. Would I buy one....yep, but it won't be at some ludicrous price like 20K over sticker. It's people like that who drive up the prices only to get retail sticker shock when they go to sell it. I think the car looks tough...I'm just pissed about the name! :mad:

08-27-2006, 04:30 PM
i havent driven the new Z06, so i cant compare the 2 cars, but with it weighing considerable less and the sam hp, im sure the Z06 is faster. i didnt pay 20 over msrp for my car, but some people probably have. when the new mustang gt came out, i think they were going for over sticker. i think the new shelby looks good and it has plenty of power even if it isnt the fastest car on the road. from what i have been told, you can put a couple of thousand in the car and have 650 hp, then you might be the fastest. im gonna let pro dyno do a tune on mine then see where i want to go from there. i will keep you posted

turbo~ I'm glad you're enjoying your new purchase but like cobrabitn said I think FORD forgot about the loyalty and true dedication of all of the current/previous Cobra owners. Given the choice between the new Shelby and a ZO6 I could be easily convinced to go with the 'Vette. This coming from a Mustang/Cobra owner for a very long time. Sure, you could make the new Shelby have 650HP but the same could hold true for the ZO6. Obviously the "best bang for the buck" is going to be the Mustang and with it's heritage it'll do fine today, tomorrow and most likely the future.

Actually, I am coming up with a better power to weight ratio for the Shelby than the Terminator. If the Shelby weighs 3950 lbs with 493 rwhp and the Terminator weighs 3650 lbs with 397 rwhp then the ratios would be .125 vs .109 so the Shelby would have a better power to weight ratio assuming both cars have no mods except a computer tune. The Terminator would have to have 456 rwhp in order to have the same power to weight ratio as the Shelby. Just by my calculations... rwhp/weight

don't take it personally ;) if you like the car, that is all that matters :thumbsup: its a great car, enjoy the hell out of it. As for some of us current\previous Cobra owners, there is a bitter resentment towards Ford and the way the went about making the car, IE: shelby name (and I mean name, as SVT designed the car and Shelby just drove it a couple of times and said "cool"), not caring about the weight(cmon, I have no doubt it come out of the box capable of doing well, but for those of us who want to upgrade and track the car, that is a huge minus), not having IRS option(can't please everyone with just having solid or just having IRS, so why not offer the option on a chassis originally designed for IRS). Basically Ford ticked off alot of thier niche Cobra base with the way they went about with things. I believe they had alot of loyal blue oval owners that are now questioning loyalty to Ford.

I rather have a Ford racing version of this car or a Legend or the true Ford race version with the 5.0

too much Hype I can build a faster car for less

I don't think anyone is disputing the horsepower of the Shelby, but the power to weight ratio isn't what it should be.

Heck, M1A1 Tanks have 1500 horses, but I bet I could take one:D

I love the analogy! Power-to-weight ratio isn't the only issue regarding a heavy pig of a car. Weight affects EVERYTHING a car does. So yes, a heavy car will not brake as well. It will not handle as well. Sure, 14" brakes...big deal. So what if it stops well once, which I argue it does not, but it won't handle a good track day because the car will fry the brakes. As far as handling, all the road test magazine articles show what is painfully obvious in the design of the car..UNDERSTEER..PUSH..TIGHT, whatever your racing interests, the GT500 can only drag race well. It ain't no Z06 competitor...no way! :bounce:

Don't get me wrong, you GT500 Lovers, I do dig the GT500. It is a cool car, but a Corvette Killer it isn't. It's just not a sports car. It's a muscle car to me, nothing more. Taking it for what it is, and you have to like the car, a lot!

I see you have been to my GT500 hits the track post! :thumbsup:

I can assure you that the GT500 is WAY and let me stress "WAY" easier on brakes than a Terminator (or any other Mustang to date for that matter) is!

:D

Yes, but you said you put on custom pads and installed cooling ducts, yes?; very good I might add. I am referring to the stock vehicle's brake and weight issues...I doubt it'll hold up on a 30-minute track stint. Fade will rear it's ugly head I'm sure. Yeah, street components aren't necessarily for the track, this I know too. I'm just saying, a stock Z06 wouldn't see brake fade (if at all) like a stock GT500 would. That's all.

By the way, I'm not getting "WAY" :(

Taking a car like this (or any car running sub 2:40 lap times), to a track event at Road America without brake cooling would be stupid at best.

If we compared the GT500 with it's 14" (1.250" thick rotors) front Brembo calipers to a Terminator with 13" (1.100" thick rotors) PBR calipers, no brake cooling, stock OEM pads on BOTH cars and stuck them on a road course such as Gingerman (let's say), there is absolutely no question in my mind the Terminator will fry it's brakes WAY before the Shelby will. Period! (get the "way" now?) ;)

Don't forget the Shelby has a twin piston rear brake caliper and a much larger brake pad as compared to the single piston Terminator rear brake caliper with a smaller pad! :)

YMMV :thumbsup:

So the GT500 does have twin-piston rear calipers? I saw that in the brochure, but nowhere else. I even asked a dealer and they said the rear brakes on a GT500 were the very same as a GT. Do they bolt in to the same location and bracket as the GT's???? It's the same rotor, yes???

I want the upgraded calipers for my GT!

I think that it is obvious that the brakes were not designed for road coarse racing where the heat and heavy use would degrade the pads and rotors.

If you are really into road racing that much it would be better to invest in the race version of the 05 mustang FR500 but that would cost around $100k. Much less weight, full roll cage, and different suspension as well as brakes, etc.... not sure if the car comes with a motor. I think you can buy the body with out the motor and drivetrain so you can finsih the build yourself which would cost as much as the Shelby gt500.

On the topic of brakes and increased weight, it would be interesting to find out how long the pads and rotors would last with everyday driving. So far I am still on the original rotors and pads on my 04 Cobra. Pad thickness has not changed since the last time I had it State inspected (they measure pad thickness and rotors and provide a printout along with other parts of the state inspection). So far 24 passes down the drag strip, and lots of spirited dirve it like you stole it driving. (probably just a scratch of what road course racing would do to the brakes).

The FR500C comes as a complete turn key racer for $125k.

The GT500 is just going to be my daily driver because driving a diesel Excursion for the last 2-1/2 years is getting old. My 2000 R IS my track car and does a great job on the track. But if I ever need a back-up track car, the Shelby will do a fine job!

Sorry, I mispoke. The rear caliper is a single piston, not dual. But the pad is somewhere in the vicinity of a 40% increase in surface area over the SN-95.

Sorry about that!

Oh, so it's the same as the GT after all. I was all ready to order two new rear calipers from the GT500 for my GT. Oh well.

Larger pad is good for pad life, but it's piston surface area that gives you more braking power. I wonder how the rears compare to the SN-95 rear calipers???

Just to confirm, you looked at your rear calipers and saw only one piston chamber, yes?

Correct. And the piston appears to be larger than the Sn-95 although I did not measure it!

Bruce I don't care what anyone says about the cars, I still want one. HOWEVER, I just can't pay more than MSRP for a Ford, even if it has Carrol's name on it! :D :thumbsup: I guess I'll be waiting a year or so to get mine. :D

Big Daddy, all you need is a little patience! I'm guessing by next Summer you will find MSRP? Maybe sooner? It will be worth the wait. Trust me! ;)

I was wondering if it's larger than the S197 GT, not the SN95. I don't suspect you have access to a GT rear caliper to compare it to your GT500, do you?

My guess (and this is only a guess, but knowing Ford) is they are standard issue S-197 Mustang GT rear calipers. Given the massive braking capabilities of the 14" Brembo's up front I don't really see a need to make a special rear caliper for the GT500?

ac427cobra, I looked at both a GT500's and a GT's rear calipers today. I found out the mystery why there are different Ford part numbers for the two respective OE calipers. The GT500's are painted black to match the black Brembos. Otherwise, they appear to be the exact same caliper, unlike the GT500's brochure claim that it's a two-piston rear caliper. :confused:

I just got my 14" two-piece Stoptech front brake kit (in red). I also will add Steeda's 13" upgrade kit to the rear (after I paint the rears red, of course). It'll be neat to see the improved braking with all that extra meat and steel braided lines behind the rims...which will be GT500 rims, by the way. ;)

Thanks for the help. :thumbsup:

Angel's look like the stock S197 GT Calipers Painted Black. Preliminary Ford vehicle specification shows them as being two piston, but to my knowledge, the final release of the document is not official yet.
