Gforce Mini tubs
#21
We welded our tubs at several places to make sure they were solid and sealed the rest.

I am not sure what size tire and wheel combo you would need to get a 20 x 12. We have a lot of customers running 18's with larger tires. A few running 19's. But, they have to do a lot of measuring to get the setup just right.

Ok cool. Should be able to run a 20 x 10 with a 295 tyre.

I have the 4 door version of the GTO which has slightly less room from standard. I do understand about correct offset, I used to work in wheels & tyres, but was after a ball park figure so I could work from there for wheel and tyre width.
