Anyone out there point me to a reasonable alternate ($) to the concentric washers that control the rear camber? One moderate off and the setting changed ruining a good track weekend. I have the GT3 LCA for the front.

 

I've had issues with the eccentric bolt myself. The only solution, other then the GT3 LCA, that I know of is to be sure the screw is sufficiently torqued. Since I've been paying attention to this I haven't had problems although I've had my share of moderate "offs".

 

Camber? Do you mean the rear toe??

I know he sells a lock kit for "HIS" 996 toe links.
Can't imagine he wouldn't have the same or similar solution for the Boxster/Cayman.
If you are in fact refering to the eccentrics on the control arms-No. Just be certain to nut and bolt and check torque before every track event.
