Figured i'd post this in the LS section aswell......

What I have is an 02 Trans Am. Over winter, i'm looking to mini tub my car using the Wolfe mini tubs, adjustable perches, springs, and a single adjustable anti roll bar. What I already have are the offset lower rear control arms and a double adjustable panhard bar. The rear is aprox. 4" narrower than the stock 10 bolt. I want to run a 325 DR on a 15x12 wheel.

1. What backspace will be needed to run the 12" wheel?

2. Will a 325/12" wheel combo work with a mini tub or will a full tub be needed?

3. If there is anything useful info that can be provided it is appreciated!

BS usually works out to be around 5". Ive seen cars with 6" of BS that have the tire right against the lower control arm even with offset ones. This can work with slicks, that get taller, but not with a radial. Mini tub will be fine.

Thanks John. Never thought of Andy. Do you know if Tuff (lsx tuff) runs a mini tub with a 12 and what size radial?
