So I have just finished my install on my rear camber plates and complete rear shp strut housing conversion with my Cosmo dual spring coilovers. What is everyone running for alignment specs for Auto-x?

I have not attempted to get realigned yet just got the car back down and sitting on its own weight.

With toyo R888 275-17 rear and 255-17 fronts I run -1.5° camber in the rear and about -3° front. 34psi rear 36 front. As for the rest of the specs I'd have to look it up. I think I run a little tow in also.
That's just me playing with camber until it wasn't too tight or loose on hard corners. I know on cooler days a little less front camber seems to work better. Could just be my sub par driving style :)

34-36 psi? That seems high. Why not drop it down to around 28-30 so when the tires heat up you don't risk a loss in traction?

Any less and I get too much tire roll and loss of traction. The extra psi keeps the tire flat and keeps traction. At 28 I would destroy the sidewalls. I chalk the tires and adjust pressure accordingly to get right to the sweet spot using all the tread, but no more. You want wear right up to that little arrow on the sidewall. Then send it!

Edit: On the street I do drop them back to 32.
