The Yokomo RD-301AD is an aluminium rear suspension mount crafted for the RD2.0 chassis. It enables adjustment of the suspension pin distance from 57.2 mm to 60.4 mm, and the centre setting (#1) corresponds to the standard suspension pin position for an even-handed baseline setup.
This mount places the suspension pin 1 mm lower than the standard resin unit, increasing the roll centre adjustment range. That extra 1 mm allows for finer balance tuning to suit handling preferences and circuit surfaces.
The RD-301AD works with multiple Yokomo chassis models including RDR-020, RDR-020G, DP-GRA90, DP-GRA90R, DP-GRA90W, DP-GR86, DP-GR86G and DP-GR86W, offering flexible compatibility for rear suspension upgrades.
