"we are going by according to experience.
also camber has alot to do with clearing of coilovers too.
so anything from +20 to +29 offset is what we recommand."
That was talking about the Front
This came from Sam of
www.jspec.com
He told me for 17x8 go +25 offset and the back with 17x9 +38 offset was fine.
I just need to save up and get my wheels!
