Thrashed on my new RS3s at an auto-x school in 80-90deg weather. They can REALLY tolerate heat and take abuse without getting slippery, highly recommended! Miata-driving instructors were impressed with the grip.
Also got an alignment that I like a lot, but needs a touch more caster and/or front camber. Currently limited by bad suspension bushings that will be replaced this winter. Several instructors really liked the setup, for what it's worth.
Front:
-2.5 camber
4.1 caster (I wanted 5, that's I got)
1/16th toe out each side
Rear:
-1.5 camber (not quite what I spec'd, but the best I got, turned out pretty well I think)
1/16th toe in each side
Thanks to aMaff for advice on suspension settings.
