The RDRP "Wide" B6.3 Brass Suspension Mount D is an optional version of the D suspension block and provides a wider variety of rear toe-in settings for the B6.2, as well as additional weight to help out in slippery track conditions. These parts are handy for fine tuning the rear end of your buggy to all sorts of tracks. Suspension mounts are black anodized, have machined and polished edges, are fully compatible with the Associated B6 series pill inserts and perfectly fit the B6.3 buggy with the latest wide pivot rear suspension set-up.
