XRAY - Model racing cars

We're running at Snetterton this weekend which is a large, flowing, smooth tarmac track.

Instead or running the rear wishbones parallel (middle holes) I'm thinking of running them with anti squat (front of the rear wishbone in the top hole, back of the rear wishbone in the middle hole)

My questions are:
1) I believe this will increase rear grip, true?
2) Are there any changes I need to make to the droop? I currently run 2mm front (under the screw) and 3mm rear (under the screw casing)

In my experience, anti-squat only increased rear grip on initial turn-in as it kept the rear end from lifting up to the downstops and transferring weight to the front. But once the front started to roll, as the car came closer to the apex and I started to apply the throttle, rear grip decreased significantly until well past the apex. This is where anti-squat actually prevents the rear from rolling mid-corner and squating on exit after the power is applied. However, I always setup my car with very little front droop (1.5mm). When I used anti-squat and had problems with over steer mid-corner and on exit, increasing the front droop to 2.5mm settled the rear back down on power.

errr....a little confused here. I know the Hudy book has got the anti-dive wrong, but anti-squat is right which is back back of wishbone higher than than front of rear wishbone, not the other way round......?

It's correct on page 47 of the Hudy Setup Book. But check again and you'll find that the forward suspension holder of the arm is mounted higher than the rear suspension holder.
