Sakura D4: Suspension Blocks and Rear Lower Arms

A lot of time has been spent de-anodizing (pink) and polishing aluminum parts on this chassis, and hopefully this will be the last batch for a while. It is really time consuming.

I would have done these mods earlier, but had to wait for some of the parts to be in stock. The suspension blocks are from 3 Racing and the rear arms are Yeah Racing D3 arms. As mentioned in an earlier post, I like the D3 arms because of the narrower track compared to the D4 arms, giving a little more adjustment range by using spacers and/or wheel offset. This is a short term solution while I am waiting for Usukani to release their new rear arm design. Hopefully soon...


Besides being aluminum, the suspension blocks utilize ball shaped pivots on the ends of the pivot shaft which make them that much smoother in operation. I think this is critical, especially when running really soft suspension settings.  The ball ends also allow you to try other suspension geometries such as anti-squat, or front kick up without binding the movement of the arms. And, of course they look good.
