TobiasMUC - Are you running the same pressure all around?

In this document they are using more pressure in the rear. This seems more appropriate for a rear/mid engine car.

With a lot of street driving only it will fairly quickly wear out the inside edge.

Based on your street driving I assumed you'd want to maximize settings for the track but if you want a better street-track friendly setup then I'd go with -2.5 front and -1.8 rear (typically want rear to be about 1deg less but -1.5 is definitely not enough camber for a r-comp that's driven on the track).

No, rear pressures should be higher than front. I usually start with a 2psi delta between the front and rear with a higher rear pressure, and then adjust for track conditions and temp.
