This is the aluminum D-type rear suspension mount (57.2 – 60.4mm) for Rookie Drift RD2.0 from Yokomo.
The RD 2.0 is equipped with a rearward gearbox position, this mount increases suspension rigidity for reliable operation and improved traction.
The width of the suspension mount is a E width that can be set in the same range as the RD2.0 standard, which makes it easy to achieve a slightly narrower profile.
Fine adjustment is possible by replacing the bushings.
You will need B8-301BSA suspension bushings to complete the installation.
