7075 T6 Aluminum +3mm Rear Camber Mount for the Storm Truck and Cougar Laydown Buggy.
The mounts are aimed at astro and carpet racers that have needed to stack 3-6mm in washers to obtain the correct roll center for higher grip surfaces. These add tremendous strength to the rear inner ball mount when running a higher roll center. No washers installed is the same as the stock geometry with 3mm washer, hence the +3mm name. Must have for artificial surfaces!
