A little track crud adds some street credibility. Very much enjoy hearing that track enthusiasts with technical minds are enjoying the wheels. That is what its all about.Sorry I'm such a deadbeat. I still owe you better pics with the car not covered in track crud.
One thing I'm glad to say: I love the SV501s, they are not noticeably heavier than the CF wheels in street driving (no change to ride quality, impact harshness, steering feel).
Running 305/30-19 MPSS all around on R-spec wheels (10.5" wide front, 11" wide rear) works perfectly. The rear stretch is a tad more than the stock 315 MPSC2s, while the front stretch is a tad less than the stock 305 MPSC2s. This is because the MPSS has a wider and more square tread section design than the Cup 2 tires. The MPSS is recommended for rim widths 10-12", so it is comfortably in the intended design limits of the tire on both ends of the R ... and you don't get the big poke that 325s give in the rear with MPSS or MPS4.
The other great surprise: I am running -2* camber and 0 toe front, with -1.6* camber and 0.3 deg total toe in rear. On the Cup tires on the street, the front end really tramlined and it was a bit of a handful with zero toe - but it was awesome on the track. With the MPSS tires mounted, the car is MUCH more comfortable and relaxed on the street, even with the exact same alignment settings ... not to mention transformed in the rain (duh).
Nice to be able to drive the R anywhere through wet or dry weather without anxiety.
