I would be scared to drive them on the street not much tire to road surface,
Nah, you'll be fine. Unless you corner real fast (faster than normal traffic), you have nothing to worry about. RX7's are light cars, my stang weighed probably
When you guys run skinnys on the front do you max out the air pressure?
I ran it about 40psi, but only for that last ET advantage

I never had any problems with wearing funny or slipping around so I left it like that.
Im still looking for some 10 hole Mustang wheels for the rear of my car,Once I get them I will see how high I got to raise the back then decide how wide of a tire I can go
I've got a set of 4, but I'd feel stupid getting rid of them cause I know I'll need them. I may have a pair of "turbine" wheels from GT's. I think they are the same size, are supposedly the lightest stock wheel made from the factory for mustangs, will match the fronts in the pic kinda well, and since they were given to me, I'll give them to you. I'll try to remember to look around the garage for them. If you don't hear from me, keep bugging me and I'll look for them.
