(I also posted this in the 987 forum but am reposting here to catch the attention of more track junkies).

This season I'm driving a new-to-me 2006 Cayman S dedicated DE car and I'm still figuring out how to set it up for the track. The car is 100% track and never sees the street. Currently my alignment specs are;

-2.4 deg F camber
0 deg F toe per side

-2.4 deg R camber
.06 deg R toe-in per side

The suspension is highly modified with JRZ Spec Cayman coilovers (700 lb/in front, 800 lb/in rear) and monoball Tarett control arms and links everywhere. Tires are Pilot Sport Cup 2's. It also has a Guard LSD.

I've done a few track days so far and I'm seeing a bit more tire wear on the outside shoulders of the front and rear tires than on the inside shoulders. I'm thinking of adding a bit more negative camber in the interest of extending tire life. How does -2.7 deg of camber sound for front and rear?

I've also found the rear end of the car sometimes fishtails a bit under hard braking from high speed. This could be a lot of things but I'm wondering if more toe-in on the rear, maybe another 0.1 deg, would help improve rear end stability. How does .16 deg rear toe-in per side sound?

There's tons of info on this but move F to at least -3.0, R to -2.5 The LSD should have fixed the braking problem.

Try increasing the rear toe setting. Not sure what wheel size/tire you are running ,but we try -1.6mm-2.0mm per side and see how it behaves under braking. Your alignment tech should easily be able to set his machine up to read MM instead of angle....
