AST Camber Adjustable Top Mounts – BMW G20/G21 M340i & G8X M2, M3 & M4
Product Description
AST camber-adjustable front top mounts for the listed BMW G20/G21 M340i and G8X M2, M3 and M4 applications allow front camber adjustment while retaining the original dampers. Part number TMA-B20-A2-20F is designed for the original-equipment damper and spring arrangement, not as a universal mounting solution for aftermarket coilovers.
The adjustment changes the upper mounting position of the front strut, providing a way to establish camber as part of the wheel-alignment setup. It is separate from ride-height adjustment and does not add a damping control. The product therefore suits a build where the original dampers are being retained but additional front alignment adjustment is required.
AST's original-strut camber-plate range uses a pillowball-bearing design and is intended for correctly matched original springs, lowering springs or adjustable lowering springs. On compatible cars with factory electronic damping, the original electronically controlled dampers can remain in service. There is no need to treat an original-damper top-mount installation as a non-electronic coilover conversion.
Check the specific chassis and spring/damper arrangement before ordering. Fitment to the G20/G21 applications does not establish fitment to every G-series BMW, and these mounts should not automatically be paired with an AST or MOTON coilover kit simply because both products list the same vehicle.
The product is supplied as a front top-mount set. Final camber should be measured during alignment, with clearance and the installed suspension arrangement checked at the chosen settings. No universal camber angle is implied across all the listed applications.
