Yes you do, i think you can still use pad and spur from kyosho but you definitely need the slippers disc from the B4.

Actually the design on the ready set shocks isn't like the Short Course truck (similar to velvets) so it should work better. Unless I looked at the wrong picture. I guess we will find out.

The plastic big bore shocks look 1/2way decent. They go together like traxxas shocks...

I would pick up a cheap set of alloy caps for them.
