I have the standard pilot cup tire, not the + version.
How badly is -3.0 camber going to cut the inside of my tires when I'm on the street? At 2.2 it's really not doing very much that isn't evened out on the track so I don't know if that will really change much.
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.
