Klinik RC have introduced a new +3mm rear camber mount for the Schumacher Cougar Laydown. The mount is 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. The part adds 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.
