Anyone fitted bigger alloys than the standard 15" ones, and Nitrons to their MR2 (Mk2). Thinking about tweaking the engine a bit too. I have Nitrons fitted to my Tamora and are very impressed with them.
I currently have 17's on my 2 with koni susp'. I would say you would be better off with 16 or 17's. I have 235/40's on the rear and 205/40's on the front, using Toyo Proxies.
