I also recently made the move from Hoosier to the R1-s in my BSP-prepped Audi TT quattro, and your reviews helped sway me. So far I'm really liking them because of the raw grip and their ability to manage heat. Perfect tire for pros and tours with multiple drivers, and I don't mind the slight loss in transitional sharpness (being accustomed to to anticipate with the inputs due to numb cantilevers slicks in my EP car). I just wish they had a 295/17 because the 315/17 are a bit tall compared the 295 Hosiers I used to run in that car when it was classed in CSP.
The tires really came alive for me at 32/26 psi hot and 3.5/1.5 degree of static camber compensation in my 3100 lbs AWD TT (numbers front to rear). I originally started at 35 psi hot based on early reports that they needed more pressure to work well due to the softer sidewalls when compared the the A6, but it seems that they work optimally at about the same pressure range in my car. Without having the car fully dialed to take advantage of them (only two asphalt events so far with no real suspension adjustment besides the ones mentioned and rusty driving after more than two years of inactivity), I'm able to get within 2 1/2" raw of a well prepped and driven SP GT3 capable of contending for National title. I haven't done any Pro or Tour with them to fully gauge their worth, but the initial grip level is well received.
The taller 315's forced me to massage the front fenders a bit, raise the front a few mm to avoid full-lock rubbing, this also raised my air dam to about 3" of ground clearance... but besides that it's all good.

Thank you, I was already thinking about selling the current wheels and jumping to lighter wheels.

It is interesting to see the rather large variance people are running in tire pressures. I honestly cant tell in my car what is faster. 32psi gave a rather linear temp across the surface, but I never tested that at 40psi. This weekend I ran 39 psi on my last run and it seemed to work just as good with it being faster than 35psi I was running.

We made some big adjustments on my car which we will test this weekend. Still, anything higher than 38psi in my experience resulted in extreme lack of grip. Chalking the sidewalls brought me to our current pressure of 37. Though I think we tried as low as 35 with excessive roll over. I can't imagine running 32.
