Guys, set the Sways to stiffest. Jim runs UUCs on full and I run R/Ds on full. We have exactly the same rear 24mm, but I have one mm thicker in the front at 27mm. The handling was completely neutral (if the car was going outside the line, it was doing it with all 4 wheels).

As far as pressure is concerned, if it's wet run higher pressure to better cut throught the water (38~40 FR (225/45/ZR17)/ 41~42 RR (245/40/ZR17). In the dry I would also run higher pressure to save the tyres a bit better from chunking. You may lose a second a lap on that, but it really doesn't matter that much since you are not competing, but just having fun. :)
