I got into a little wet weather (just wet, not a deluge) on the fwy just after I got the car. Next day I went out and got another set of wheels/tires, with lots of tread, for the street. Factory Reproduction FR27 wheels and Nitto 555's. TW is 320. I kept the OEM wheels and tires for track only.
As a test, I tried the street alignment settings at the track. Predictably it was tearing the GY's up. I set the alignment at track settings and will leave it there. Not much driving on the street anyway and estimate, with much harder tires and swapping them side to side, should get pretty good mileage out of them.
FYI, at OEM track alignment settings, I'm getting +/- 5 track days out of the GY's. At my track that equals about 350 miles. Still need quite a bit more camber on the fronts though. Plan to go to -3.8 at the front and hope that will balance the wear a little better. The rear is at -1.9 and wear looks pretty good but I think I'll go up a tenth or so there too.
