Track Alignment Specs
New here and new to Porsches.
I'm running MPSC2 tires on my lowered 13' C2S. After a few track days and having logged tires temps and tire pressures, clearly the car needs more negative camber to get the best results out of the tire.
Any recommendations as to what alignment specs would make a decent track day set up?

I think you would need camber plates or whatever is available for this car to really get a track alignment.
I had mine put to max on stock suspension basically, max they could get from the front was -1.6 and went -2 rear on my 991 GTS

Max negative front, which is around -1.7, toe, -2 rear with stock toe setting works well. Mine is a sport package c2s, non PDCC. PDCC cars can get away with but less camber since they don't lean as much.

non pdcc 991s:
I'm at -2.5 front on my 991s using Tarett plates which should become available for sale soon.
I settled on 0 toe up front closer to -1' minute a side
Caster is at 7.5 degs?
rear is at -1.75 now, tried -2.0 and may go back to that much, but am not sure if its helping my lap times vs more contact patch on exit
rear toe is at +10'

I run -2.2 front and rear for camber, 1/4 toe out front 1/8 toe in rear currently. No caster adjustment available and don't remember what it is after the new set up. Works very well on spasm with MPSC2s. Would love mono ***** and at least a doubling of spring rates with these tires but I'm not going down that route with this car.

Apex Ace,
It would be interesting to see your; tire temps & setting at time of measurement.
If you don't mind sharing.
Also, is your car SPASM & PDCC.
Gem Mookherjea,
Are you running Toe-Out in the rear?
W/ PDCC & SPASM on PSS; I am finding I get very little outer shoulder wear.
Camber: -1 9/16 F, -1 7/8 R.
What kind of wear do you guys see on PSC tires?
I once tried measuring tire temps, with a Probe, but it was a PITA and not conclusive.
Measuring temps with IR is suposedly pointless, according to Longacre.
