i have a 99 cobra with exhuast and shifter. I drive this car everyday and every friday night i got to the local dragstrip.Know the only strip we have is a 1/8th mile. I was told to go with a 4.10 gear but some poeple say so with 3.73 or 4.30.now i still need to stick the tires to the road. Which gears would be best and what would i top out at with each gear

I am going to say 4.10's because they are a good compromise between track and street, although you could probly run faster at the strip with 4.30's or even 4.56 gears.
If you are planning to, or have a blower, I have heard 3.73's are the better choice?
You will probly get opinions all over the place on this. :thumbsup:

I just went with 4:10's in my '97. I am glad did. Since I don't plan to ever supercharge this car. They are great. I havn't tried to top it out yet. (I'm a little gun shy since I got a ticket for going 100) But, before the install, I would shift out of second at just under 70MPH, now I shift out of second at about 50-55. It actually makes it easier to drive around town too, because I don't have to go all the way down to first when making a slow 90 degree right hand turn. Another benifit, I acutally use 5th gear, when before, even going 75-80 I wouldn't shift into 5th and I'd still be well under 4000 rpm's.

Good luck.

I just put 3.90's in mine, and I'm pleased with them. I haven't had the chance to see where "top out" in each gear is, 70 mph = 2500 rpm. If you get a chance, see if there are some local cars around with different gears, and see if they'll let you drive them to see what feels best for you.
