I may have screwed up with the 4.10 gear install. I calculated my trap speed and it is slower than I thought with a 28 inch tall tire. My axle is laying on my shop floor. Hopefully I will get it in this weekend and I can do some measuring.
I figure I could run at least a 29 inch tall tire. I come up with 131 trap in fourth at 6200 (stock bottom end with a 3.6 KB) which I think is too slow. It may be a good combo for an 1/8 but I'm not sure about a 1/4. Jegs lists Hoosiers 29.5 inch tall tire with a 96 inch circumference. I come up with 93" or that tire is actually 30.5 in diameter. A 30.5 tall tire would give me a 137 trap speed which I think would be reasonable for a full weight GT500 around 20 psi.
Anybody know what the maximum tire height we can run and sectional width? If I can get a 32" on it would it run a good time as opposed to a 30". I have the Steeda sway bar relocation brackets so I can run a 15".
Any help appreciated. I hope to be on a track in 4-5 weeks. It's been fall of 2005 when I sold my 2003 Cobra the last time I made a pass.
Thanks
