I ran the MPSC tires for the first time this weekend on Thunderbolt at NJMP. I previously ran Toyo R888. Using 235/40 F and 265/35 R on 18" wheels, the sweet spot seems to be 33F and 36R hot. This coincides with Michelin factory data for a Boxter but they used a 225/40 front tire. My car has stock springs and struts, GT3 front bar set in the middle and Tarret rear bar set full stiff. Using GT3 LCA, I have -2.5 camber in the front. My tire temperatures indicate that I could use a little more negative camber. I did experience a little understeer in a few spots and am thinking of running the front bar one hole off full loose. Has anyone tired that set-up? Overall, I preferred the MPSC to the R888 for my style of driving.
