Hi turbo owners,

Is anyone who's tracking their turbo or turbo S using aftermarket two-piece control arms upfront to run more camber? If so, how much camber/caster, and more importantly, did you have any issues w your front axles as a result? If not, how did you achieve reasonable camber to run RComps?

Having some freak issue w my setup w the 4S and the turbo seems to be the only other awd 991 that sees track time, so I'm wondering if anyone else has some experience using adjustable control arms.

A/S

If you achieve camber in the AWD 991 by using a split LCA, you need spacers for the ball joint into the wheel carrier, many instances of axles popping out.

Aftermarket upper camber plates achieve all the camber needed for Hoosier, slicks, and anything with less grip. My 991TTS can go up to -4.0 camber, but I have it set to -3.5 (ideal for Hoosier).

Thank you that's very helpful.

Are you running the Tarett one?

3.5-4 seems like a really high number to achieve w just these camber plates, they seem to provide about -0.9 extra only for the OEM struts/springs. Is your turbo lowered, that could be how you get the rest of the camber?

For lots of camber you need toe links also, OEMs are too short for proper geometry, especially when lowering. Good thread for track see Tracking the Turbo.
