No, what Simon means is the front hole has been drilled 4mm higher than the standard hole so you run no washers under the rear mount and all the adjustment for anti squat is then made on the front. If you had 4mm of washers on the front you would have zero anti squat so with 3.5 mm the car has .65 anti squat, if that makes sense. If you remember I think I showed you at RHR, if you take a look at the report for the national there is a picture of Grants car with it on. The idea is about trying to raise the pin or lower the diff height.

It’s as high as no spacers on the rear, so as I said be for all adjustment is at the front keeping the pin as high as possible.

One team member has drilled both holes 4mm higher say’s its very good with zero anti squat.

At the risk of being a touch Anal - 55 = 1.3208mm - according to this handy chart I have here!! 54 = 1.397 just for reference!

Whatever suits really. I prefer it to the setup that Grant runs on the shocks as I dont have any weight on the car whatsoever. Have tried it with numberous different weights and it just doesnt suit me. I have ran this combination of pistons at Bury Indoors, Kidderminster, West Bridgeford and RHR and only ever alter either the oil by 5wt, or go up a spring all round to Blues and Greys - works best for me.

Play around and see what your thoughts are, but if you do run weight or alot of it, Grants shocks are setup for that.

Hi Si

Just setting up for this weekend, i noticed that you used 2 hole for rear drilled to 55's but the hole is already that size in the 2 hole pistons. When i built the shocks it felt over damped at the back with 30wt oil compared with the front (3hole drilled 55's with 35wt). Could you shed any light just a little confused i thought the back should be lighter than the front

Cheers

Im sure someone will post but im pretty sure that the standard holes are not 55, they are smaller. The backend shouldnt feel over damped, infact mine normally feels quite light. Im not going to be there this weekend so cant really show you, but i definately have this setup in the rear and have used it all winter.

If you are running the pin higher at the rear, with the wishbones level, surely this is effectively lowering the car? e.g. the chassis will be lower to the ground than with the pin at its normal mounting point.

Actually thinking about this further. If you keep your shocks exactly the same as with the pin in the normal position and raise the pint. The rear of the car will sit slightly higher. You will then have to wind down the shock collars to get the w/bones level at the rear, which will mean the front of the car will be nose high, menaing the front will have to be lowered too?
