Thanks for the feedback so far guys. Brake-pads and liquid are already at track-standards. All the rest is stock. As regards camber adjustment, clearly, I would prefer avoiding to look for an impossible compromise. This car is my daily driver
.
Upon looking into Tirerack technical recommendations for the PSC I found the following:
(start quote)
Vehicle Wheel Alignment Recommendations
Camber should be negative:
Acceptable 1 degree negative
Preferred 1.5 to 3 degrees negative (for most basically-stock or moderately-modified cars, the "sweet spot" is going to be in this range)
Maximum 4 degrees negative
Proceed carefully with camber adjustments. Too much camber means giving up efficiency in braking and accelerating. Achieving the right balance between cornering grip and straight-line grip (braking/accelerating) is key. For those enthusiasts who simply want the opportunity to explore their vehicles' limits with higher levels of grip, but who don't want to make serious modifications to achieve high negative camber values, Pilot Sport Cup will still operate effectively with more conservative factory settings for camber.
Caster should be set at the vehicle's most positive recommended setting.
In most cases, toe should be set at the middle of the vehicle's factory spec for each axle. However, depending on the competition situation (tight road course, more open, flowing road course, autocross, etc.) it is possible to materially affect the initial turn-in of the car and its stability in high-speed transitions through manipulation of the toe settings. Care must be taken because Pilot Sport Cup tires generate significant levels of lateral force even at very small slip angles; thus, large toe-out or toe-in settings can have big effects. In general, a good starting place is near zero toe (parallel) or the minimum value of the factory spec for toe-in at the front axle. At the rear axle, moderate toe-in (usually the minimum factory spec for toe-in) is not a bad place to start.

I am also curious about the statement:
Pilot Sport Cup will still operate effectively with more conservative factory settings for camber. I assume this means effective yet not 100% optimal and implying uneven wear of tires.
Anyone know what is the factory camber setting on a '99 996 C2???
