too big for me. 20" is the biggest I would go, just slam the sucker

 

I think in most cases, 20" is the largest that looks ok on 1st or 2nd generation GS's. That said, it's your car so do what you makes you happy. But a piece of advice would be to follow BlueLex's example. Darker finish + a CLASSY looking aero kit will help prevent the large wheels from visually overpowering the car.

My burning question for anyone out there with 22's: Whats the steering radius like????

 

I 2nd that!
