If you are running the aluminum rear suspension hangers... you are set. Every other piece on the car is only going to break if you do something you really shouldn't of done. Nothing else on the car is broken "over easily". The one piece you may want to toss in your bag anyway, is the rear upper bulkhead.

Now, if you don't have access to parts at your track, I would also toss in a full set of arms, caster blocks, and front shock tower.

My rear bulkhead had a ballcup pop off. I since then bought a longer ballstud and place a nut on it. Alloy RF2 and alloy rear hubs and you're all set.

What's the part number for the tiny tool that we use to assemble the K shocks? It's 158 in the instructions manual, but i don't find the reference...

Cheers

Is anyone running a full size stick pack in the mid-motor config? I just don't see how the battery is held in place on the motor side. The instructions only show to install the front battery mount. Seems as if this thing is going to slide all over the place.

The image on the page should show you that the part you're looking for is on the right side of the tree.

I had to do some digging myself to figure it out - I remember that the RF2 block was the only piece from that tree that I used in the build.
Thanks Matt. I did not think of that, only looked at the exploded view.

one has thin walls and one has thicker walls around the hole. Use the one with the thicker walls. I made the mistake and put the one with the thinner walls and it broke on my second race day.

Does anyone have the part #s for rear suspension mounts in aluminum?
