Camber: FT more than 3.5, Rear more than 2.5
Toe: A very small amount out on the front, and about twice as much in on the rear.
Caster: I have the Whiteline offset busing on the front LCA, and the Raceseng CASCAMs. They are both maxed our on caster right now, more than +6.5.

Thanks, I understand - I tried -3.4f/-2.7r per @CSG Mike suggestion, with max caster on Ohlins (adds about 1 degree), shaved and heat cycled Toyo RA1, and it worked great on track. Didn't scrub much rubber in about 8 track and 1 ax day with them, need to push harder. Will look at the pyrometer more closely but I'll go with -3f/-2.5r this year considering my car is primarily a daily driver. I also have a little stiffer springs now, from 343lb all around to 380lb f/425lb, struts revalved, but that shouldn't have too much impact beyond helping with rotation...little bit in fast corners and more in slow.
