I just bought 20's with 255/35/20 and 275/35/20. Eibach prokit, d-spec which will take care of the ride quality. 20's just look normal on the S197s.

Ive got 275 in the rear and 245 in the front and 19 " wheels, The wheels I have are extremely light aswell, lighter than stock. It all depends on what you are going after. chrome is the enemy of hp, chrome is very heavy.

Man 20s look so awesome on our cars!

I have 20" Foose wheels on my 08 GT and they ride great and I don't notice any lose of power. Maybe just me but I really like them.

I got 20" foose hornets and they look amazing on our cars, but I must admit you can feel the difference over the stock rims. I have a turbo on my car making 440 rwhp and 465 rwtq and can tell a slight difference. Probably 20 rwhp is what most say.

20's def slow you down.

Best with 20s = 13.9

With 17s = 13.2

I like my 20s for the street but sometimes it is a little rough with the 35 side wall I think after the DR go on it will help alot .
