[QUOTE=Nilks;9805405]Update:
I tried some different driveshafts and even tried putting the rear driveshafts in the front, with no success at all.
I really don't know what is wrong, but this isn't just normal wheel-chatter. At the end of the straight at my home-track, we have a left sweeper. When I apply steering at the end of the straight, I can feel the car "jumping" (due to vibrations in the front) so it won't steer in properly and it won't brake.
I am about to give up. The car is un-driveable, and I can't figure out why. I wanted to buy the 417X, but that car is probably 2 months away (if we should believe the rumours).[/QUOTE)
Seems normal to me also...
Lift the suspension arm up so as you simulate the arm position at ride height to its position on the track.
The extra droop without the weight of the car on the tires will make the chatter worse...
