Understood, but I have the Solstice Performance book in front of me. Page 88 lower left corner (Definition Basics) is where I gleaned that info. I could not see the Service Bulletin referring to race alignment, but I am aware of what it says. That said, on page 16, there is a section that says Performance Tips, and the alignment specs come after the statement that these are suggestions to us to "get started". Over 5 years, a lot has been learned about what the platform likes. On pages 90-91 there are captions for each picture, and they do reference front and rear toe IN, front camber 2.5, rear 1.8, and all running Hoosiers. Street tire will benefit from the same settings although pressures would be different. Rear toe in will help keep the rear from "roll steering" as much as with zero toe, and front toe in will soften turn in, thus inducing a bit of push there as well. Solo or track, similar adjustments will net similar results, but at higher speeds, one should make smaller adjustments.
