DB01 rear suspension mount screws

[Migs]

Hey dudes

sorry to bother you all again, but ive just noticed after doing a few weeks of club racing, the screw heads under the chassis that hold the rear suspension mount on have copped a real hammering and im using tony's screws, one of the hex's at this stage i cant get a hex driver into, the rear suspension mount itself is worn too, i didn't think i was running my ride height too low, but i may well be, what sort of ride heights are you boys running and have you encountered a similar issue as i have, there are a few big jumps at the local club ive been racing at, but i tend to land on the down slope, so i dont end up with too many hard landings on the flat

thanks
