Basically anything fits that is relevant.
You could have a buggy with longer arms, gear diffs, more ground clearance (damper stay + truck dampers) or you could just have an electric shaft driven truck
That also means that many of the option parts fit the SB, namely the alloy hinge pin holders.
Hopefully the steering rack of the RT4 respectively Velox works too wirh some changes to the top deck, steering is really weak at high speeds when the car sits planted on a grass track.
Looked at my steering rack today and figured what I could do about it.
A steering plate instead of the ackermann-rod would help, but no way around the outdrive
Did anyone try to ditch the saverspring and mount the nut backwards against the to steering arm parts so that they're locked together?
I found out that a lot of flex comes from these two parts because they do not align properly under the slightest load and the spring ist much to weak,
I now it's risky but i hope that there's still enough flex to protect the servo gears, I might try it tonight and tell you how it worked.
