Billy I have been running starspec ii a 215/40/17 but read a few post about running a 235/40/17 without issue other than at full lock. Running 275 out back. I am not running traction control and thinking about either the Toyo r888r or the new Starspec iii. Any experience with either tire? I drive occasionally on the street but primarily HPDE. Read some post with reviewers saying similar grip but the ziii last much longer. If so I will go with the ziii but not willing to give up too much grip. Running KW v3, noncompliant rear bushings, compliance clamp up front, and turbo charged at 550whp at the track. Thanks in advance on info you can share.
