The Yokomo RD-301AS Aluminum Adjustable Suspension Mount Kit swaps out the factory plastic pieces for lightweight, stiff aluminum versions on the RD2.0. The front mount measures a B width of 43.5mm while the rear uses a D width of 57.2mm. Swappable bushings allow you to alter suspension width for precise setup work.
Lowering the suspension mount by 1mm compared with plastic options gives the RD-301AS a wider roll centre adjustment window. That lets drivers tune understeer and oversteer tendencies more effectively, useful when switching between smooth asphalt and rougher surfaces.
