These plates are standard on MAX Pro coilovers, but are available here as an upgrade for the Comp coilovers or other brands of coilover. Rotatable offset camber/caster plates for maximum angle clearance and freedom of camber/caster alignment while using very long front lower arms. Allows reduction in caster when using trailing splindle style knuckles. Other coilover brands may use these if they use a 40mm bearing slot width and 60mm on center M6 hardware on the bearing housing. Optional bearing plates can be added in the shopping cart if you need to adapt these plates to other coilovers that dont share the same bolt pattern. ~ Stainless socket set screws with flange nuts included ~ 6061 half inch aluminum plate with copper anodized finish ~ Both camber & caster adjustability by 4 increment rotation & 115mm slot. Sold in pairs.
