Think about it man. Either you have to link the rear or make the wheel stick out of the wheelwell.

 

those mickeys they offer now in 20s would be a reason to widen the wheels. if you get it done post pics im very interested in this. as for not fitting in side the wells. that can be fixed!!!

 

Those mickeys are 20" wide if you dont link the rear end and narrow it they are going to stick WAAAAYYY out of the fenders by like 6" atleast.

 

yeah i was going to add 3" on the inside of my stock wheel but after futher investigation, the rim would come into contact with the brake line port on the calliper.

 

wait so technically I could widen my RT-S then?

 

GMRacer, ya you can. But not by much with out having to change other ****.

 

this would fit well with a widend rim

There's a 335 tire for 20 inch rims that will fit. They were made for Porche's. I looked into this a while ago and found about 4 shops that would widen mine to 12 inches so I could fit more rubber. Like the others said though it takes alot of moving around to get them to fit. Depending on how things turn out I still might have to do this but I put this project on hold for a while.
If you need to know the tire either PM me or turboberserker as he has the same tires.

 

Thats a new size since the last time I looked.

 

I was thinking of doing the same thing. So I guess there is no way to fit a 15 or 16x10 without having it stick out of the wheel well?
