Track Alignment

Zewerr · 06-15-2019, 12:11 AM

-3.7 is too much for for 275 RE's I had -3.7 after my first autocross alignment with 285 RE's and the inside of the tires were getting much hotter than the outside. I adjusted them to -3.1 for the following weekend and the temp across the tread was much more uniform. I settled for about -2.0 for the rear which seems to keep temps on the back pretty even. I am curious how my car will collect OPR, which may alter my preference. Also, I'm running about 6.2ish degrees of caster which will also make a difference.

Thanks, so checking tire temps across the tire is the key. Should the outside be hotter? I was trying some used 305 slicks all around and the front were close with the inside being a tad bit hotter (~3 degrees celsius). But the rears were about 10 degrees (Celsius) hotter on the inside. Plus the rear were sliding out every corner exits, don’t know if the tires are done or my rear dampening is too stiff...(front Hotchkis, LSD and rear sway disconnected)

Thinking of going back to RE71R now.
