Coming from Team Associated are new brass arm mount for the TC7.1, TC7 and TC6.2 series of touring cars. They were designed to replace the stock machined aluminium outer and inner mounts with machined brass versions for increased mass. Each outer mount is 7 grams heavier than the aluminium version while the inner mounts add 2.5 grams each. A combination of these mounts, or completely replacing the stock mounts, helps with tuning the overall centre of mass. The suspension hangers are sold in pairs and the additional weight of the mounts is laser-etched.
