Snatchy B4 on Grass

[jcb]

I was racing on what was a bit of a point and shoot grass track at the weekend, which had two 1/4 to 1/2 throttle sweeping curves shaped a bit little like a ? if that makes sense.

On the sweeping bends I, along with some other B4 drivers were all complaining that the car would snatch mid corner, as though the rear end was colapsing. Has anyone got any suggestions on how to solve it? While not losing the drive and steering needed for drag racing between the hairpins? It's how quite a few of the tracks are in my area so any help would be great

My setup was as follows:

Front:
35wt
Number 2 piston
blue spring

Middle on tower
outside on wishbone (inside was too aggresive on the really long grass)

Camber link inner on tower with one washer, inner on hub carrier

ride height wishbones level

30 degree hub carriers

Rear:
30wt
number 1 piston
silver spring

middle on tower
inside on wishbone

2 degree anti squat

short wheel base

camber link inner with one washer middle on hub carrier


I tried lowering the rear ball stud which resulted in a slight loss of forwards drive and tended to induce grip roll, while changing the wheel base had to either extra short or medium made practically no difference at all, although the extra short wheel base worked well in the damp and on the hair pin bends.


Thanks,
