Re: Front end height vs. Traction at the track?
IMO size has more to do with it. Also track prep.
I have talked to Hoosier reps at industry shows twice in the last four months, and the difference in the rubber compounds is not huge.
Going from the DOT's to the full out slick is not gonna help, for example, a car go from 1.75 to 1.55.
In my example, when I tightened up my front shocks, I started spinning. I also consistently spun about 5 feet. If I had had a chance to try 1/1 maybe I could have cut a 1.49, dunno.
People who race competitively change suspension settings to offset inconsistent track conditions.
Two years ago I would leave the track if my 8 and 9 second buddies couldn't hook, basically meant the track prep was crappy.

No doubt, once you're using at least a street slick, by far the biggest determiner of traction is track prep.
Wonder how much difference there is in sidewall construction between slicks and DOT approved street slicks?

Again the Hoosier guys said it was not significant. There is a difference but it's not huge.
Fireball has a 4.71 gear now, his first gear is incredible...
IMO he should go to a wider rim like a 15x10 and a 10" wide dot or slick and see what happens.

I think a DOT tire is a waste of time in his case.
The BIGGEST I would go is a 28x10 inch slick.
There are cars in the 7's with a smaller tire and more gear.
I think a 28x9 inch would be near perfect at 13psi and a healthy second (or in Brians case, third gear) burnout <img src="gr_grin.gif" border="0">
Also his final drive ratio is only: 12.52:1 not that big really.
Compare a 4.10 geared A4 car with converter (even more torque mult) works out to 12.505:1 just in final drive in first not counting converter multiplication.
go with a Hoosier 28x10x15 inch slick and use a 10 inch rim. That would work the best IMO.
Cheers,
Chris
Also the sidewalls are a LOT different as is weight.

Re: Front end height vs. Traction at the track?
it wraps the tires 1-3 times.
I'm concerned with the 15x10 since I'm planning on a bit of tire growth at the top end. if I stretch the tire over a 10" rim...it probably won't grow as much <img src="gr_sad.gif" border="0">
well right now it looks like 6750 rpm or so at 119. (I tapped the limiter at 6600 and stopped cold at 116) I'm going to go to about 7K and try for 122. I'll have LS1edit really soon so I'm going to set the limiter to 7200 and try shifing 6800 or so
