Rim/Tire Question for 944 S2
 

I have an extra set of 17" Cup 1 wheels from my RSA. The tire sizes are 205/55/17 F and 255/40/17 R. I am planning to utilize these at the track for my S2. Are there any issues I should be concerned with? Thanks for your advice.

Those should be a straight swap. I did it then went to 16" 968 five spokes instead. The only issue I really had, as I think some other have had was some rubbing on the driver side rear tire when turning. You could get the edges rolled. Have you cross posted this on the 944 forum? You could also try the 944S2 forum, but the general forums would get more views.
