Mjd240z did you get your wheels in yet?I like see pics.
Also the widest tires I could find were proxy 888r in 235/50/15. Hooser in just about any size, Micky Thompson in wide sizes and bfgoodrich in a 245/50/15 ta.
The bfgoodrich and m/t are muscle car style so im not sure on the cornering aspect, and hooser is good for racing not so much daily driver. Im leaning towards the proxies but they are directional so rotating them isn't going to work.
