T-Work’s have introduced new aluminium and brass lower suspension mounts for the Kyosho Inferno MP9 TKI3/4. Machined from high-quality 7075-T6 aluminium or brass, these FF, FR, RF and RF low mounts come hard-black anodised and laser etched in silver (aluminium) or gold (brass). They allow you to fine-tune the weight distribution by using a lightweight aluminum mount or a heavier brass mount.
