Hey everyone, I am new here and would really appreciate some informed advice if it isn't too much too ask.

I have a 99 SVT Cobra with 75,000km (50,000miles I believe). I am still on the original clutch and it is time for a new one as it has just begun to slip. I knew back in August that it was starting to go, but I was hoping I could make it until winter when I put it away and like to get work done. (also, I must admit, I don't have loads of funds available as I started a business a year or so ago and that is making it difficult to find the funds to get work done).

So, as I mentioned, it is beginning to slip (eg. in 2nd or 3rd around 2000rpm, if I goose the throttle a bit, the tach shows the engine revving, but the engine seems to spool a second or two later - I cetainly hope it is just the clutch slipping!). I don't think my fly is buggered (fingers crossed) and I do know from my last oil change that my rear dif is leaking a bit on the drivers side.

So, I know I need a new clutch for sure and hopefully that is all (remember, low funds due to my business). My bodyshop guy introduced me to a mechanic that works for a gearhead who owns a big tow company. The owner built his own garage/storage facility and employs this mechanic just to fix his cars and his buddies (there are always sweet rides in the shop). The mechanic is good and, because they don't run the business as a garage, he will allow me to buy my own parts and he will just charge me for the labour. (which is sweet as it saves me $$$$)

I must admit that I really do not know a lot about clutches or modifications in general. All I have done is swap the springs, lowered it a bit and put on an aftermarket air filter. Suffice to say, I don't have the mod bug and don't need THE best clutch ever, just a solid one that will allow for solid performance....aka close to the stock setup...unless the price is right.

I am in Canada which stinks these days because our dollar is super strong (CDN$1=US$1.03), but everything is still priced as if it was CDN$1=US$0.65 (eg. the exact same 4 cross-drilled, vented OEM rotors were $750 here before tax and $300 in the US!)! It also stinks because our selection is not so good. The silver lining is I am not far from the border and can get over to Niagara/Buffalo + I have a friend on NC who comes up here monthly and has brought parts up for me before (new rotors for example).

I am looking for any advice on what type of clutch I should be looking for, etc. Any advice on my situation will GREATLY appreciated. Thanks in advance!!

PS: I am going to start a new thread for this, but would any of the porblems I have described make my engine coolant indicator light come on? It comes on, but if I turn off my car, wait 5 seconds and start it again, it doesn't come on again. Engone temperature is fine and the coolant level is fine as well. Any ideas why this is happening?

It depends on your mods as to what clutch. If you are stock, a stock replacement or a King Cobra (grips more than stock). Another upgrade is the 03\04 Cobra clutch and flywheel. For a more performance option, Spec clutches are a option.

I am likely looking at the Ford Racing 11";

I don't really know anyone else with a Cobra, so I was hoping people on here could advise based on their own experiences.

Any help is greatly appreciated and thanks Cobrapace94 for posting

PS: whhat is better about the 03/04 clutch/flywheel out of curiousity?

I'm no expert, especially on the 4.6 cobras (new to the 4.6ers), I know more about the 5.0's. I'm pretty sure the 99 do not come with a 26 spline input tranny shaft, so I don't think that clutch would work.
How about this one: M7060C46, it is just a replacement clutch for the 99 & a upgrade from the 96-98's.
Centerforce has good clutches, just don't go to agressive no matter which clutch you go with.
Another thing is how do you plan on driving the car? Drag racing a lot or lots of road racing? Either requires a clutch with more holding power, but too much makes street driving more of a pain, clutch chatter and a on\off clutch, no slipping for smooth starts.
Tha 03\04 clutch and flywheel holds more than the 99\01's.
