Guys,

I am trying to make the Thunder Shootout with my new setup. I want to run the largest tire that is allowed in Extreme Modified, which is the 29.5x15x10.5W.

This morning I ordered a Billingsley Fab 9 housing and axles with their anti-roll bar setup. The new rearend is shortened 3" per side.

What wheel should I use with this? Should I run a 15x12 with a 6" BS or a 15x10 with a 5" BS? I currently have 15x9.75 D10s with a 7.5" BS (this was for the stock rear length on my current standard 9").

Also, should I run a smaller diameter spring? If so what would be a good choice for a car that is 80% track and 20% street?

I should have the rearend in the next 3 weeks and will have the car at the body shop to make the necessary modifications. I plan on mini-tubbing the car as well.

Thanks,

I have ran that same size tire on my car with out mini tubs.Not sure Backspacing but I run a 10 inch wheel with no issues.

Yes I think the little spring is good for your setup if you have the rear narrowed and a 5in bs wheel. You have to have offset LSAs I am pretty sure. With that setup you will have to tub the rear some. Kyle had that same setup in his and the W tires didn't fit. It is now mini tubbed. Do a search for BTL FED and you will see all his pics and everything.

I have the same rear narrowed the same as yours, I currently have a 15x10 with a 5" B.S.. I am running 29.5x10.5x15 right now and they fit pretty good. But you will for sure have to mini-tub the car.

Camaro, Firebird? I have a set of 29.5 x 10.5's non W's to try-It doesn't look like they'll fit on my Trans Am-I have 28x10.5's now.

camaro.and i had 28x10.5 to start with.... i had to clearence the front by cutting a pie out of the fender and welding it back together. you don't even see it unless u know it was done and the back i cut pulled the bumper cover back and removed some of the metal and cut my bumper support to clear. and had to use the bfh to clearance the inner fender part.
