I should also mention that I use the lower steering bushing from the c-hub as the shim for my center ballstud on the swing rack. It is much narrower and lets the rack move farther.

I would not recommend an aluminum servo horn unless you are on a track with friendly barriers, like an ETS track, or most asphalt tracks.
