This will prevent it from moving side to side and stripping teeth off the gear.
As far as cost after kit, the kit is race ready out of the box. Put in some electronics and grab some throttle.
Bingo. I've done very little outside the stock setup. I also haven't upgraded anything (doesn't really need it). Car is a missle. You will break front arms and shock parts but that's not the fault of the car. As far as gears, I'm still on my originals. Shim and lube and you're GTG. Now it they would release the BBs and maybe steel gears (better safe than sorry) I would be completely content with this buggy.
