Gs L-tune

20x8.5 front and rear with offset 34 would it fit on GS4?

Yes, just run a 245 in the front. I used to have 20x8.5 with 245 and 35 et and when I slammed it, there was slight rubbing on the inner plastic (more annoying than dangerous)

Good luck

The front should be rolled a little to avoid the rubbing but it should fit. The only visual issue would be the fronts are pretty aggressive and would be pretty flushed with the fender. The rear, though, won't be as flushed.

i agree, the rear won't look very good. the front is pretty aggressive though, i have 8.5 +32 and i had to roll the fender tabs in the front
