Wow. I would add some spring in the front or take some out of the rear. Maybe change your front tires?... Or, just slow down a little easier.
Move your battery pack to the rear position may also help if its not there.

Is this a new problem? Have you raced this track before?
If you run a oneway front diff is it locked up?

yes first time onthe track and the car. i could see the rear going left or right but coming all the way over the front is messed up. i did some searching and did find some people that had the same problem.

bk2 arms and hubs. You could run cr hubs which allow vertical adjustment. 3 washers is the same height of the bk2 hub.

Some guys are running a rack..a piece of carbon or metal that is the outline of the cr rack but with the ballstud vertical not horizontal. It's a little involved getting on and, without even more work, it gets rid of the sealed drivetrain idea...

Questions??

Does boiling even the graphite composite parts make them more flexible? And has anyone that has boiled the standard plastic chassis and diff covers had any breakage?

You don't want to boil graphite parts, because the purpose of them is to replace soft parts with stiffer ones.

Right, but in case the plastic parts aren't offered anymore, like the chassis and diff covers, and you want something that isn't as brittle as graphite, will they become more flexible after boiling....

I guess the plastic material that is in them would soften up a bit.

Make sure you have the correct screws securing it properly.
