Just got done prepping the car for TWS this weekend.
I'm loving having this square tire setup now, with directional-but-symmetrical tires (the RS3's). I had the local NTB flip all four on their rims for $44, then rotated them all around (diagonal). Should even out the wear from my remaining slight camber issues and from 3 weekends in a row all running CCW (TWS->COTA->TWS). Changed the oil and trans fluid (Motul Multi-ATF again), swapped the stock AP bleed screws for SpeedBleeders (finally!) and bled the brakes. Good to go for load-out tomorrow
So far on the weather reports Saturday looks ok, maybe some light sprinkles, but Sunday will probably get stormy by lunch. Will be interesting to see how the RS3's feel as it gets progressively wetter throughout the weekend. If they can't take the puddles very well, I can always flip back to my staggered Conti setup, those have huge grooves in them. I really need to work on getting a *good* rain setup for this car though. After seeing some of Mike's various tire/wheel combos at COTA, I'm thinking maybe a square set of 18x9 or 18x9.5 with some rain tires on them, like the Hoosier H2O's or something roughly equivalent. I think he had some Conti/Hoosier actual race-rain tires (as opposed to the H2Os, which are DOT-rated).
