if your having problems with your motor jumping out of mesh with an impact, the alloy motor mount is about 20 thou too thick, so when you tighten up the motor screws they arn't clamping too the carbon parts

you may of found that the front bumper is weak and prone too breaking, in the uk we've been making an over bumper, same shape, but not fastened as far as the wishbones, bolted though the center bolt and the front body mount.

i have used servo mounts with a 10 degree angle, servo saver hanging downwards, tierods slighly swept backwards, and small ball stubs mounted underneath the steering blocks, car now runs with no bump steer

as for setup i spoke to david spashett, he and the uk team have been running-

20wt oil in rear shock
green spring
standard t-bar
70wt in damper tubes
outer hole front damper plate
1 degree camber

hope this is some help, and made some sort of sense
