This is an optional Team Associated TC7.1 Brass Inner Arm Mount Set, adding a total of 5 grams. These TC7.1 FT inner arm mounts replace the stock machined aluminum mounts (ASC31619) with a machined brass version for increased mass. They are heavier than the aluminum version by 2.5 grams each.
A combination of these mounts, or completely replacing the stock mounts, helps with tuning the overall center of mass. Sold in pairs. The additional weight of the mounts is laser-etched.
