Anti-squat

[N7ELA]

How can I calculate what anti-squat I'm running. I have all of the carbon fiber spacers but don't know what thicknesses give what degrees....?

[bigred5765]

the hole drilled in them is the amount of anti squat

If it's the origional x6 (not squared) the holes in the blocks represent what degree you have ie 3 holes= 3deg.

For the squared because the geometry is slightly different at the back it's 1deg less than each block... (3hole block=2deg) I think or it could be the other way round... I'm sure a team member will correct me if I'm wrong

How is the geometry different on a squared???

Remember reading about it somewhere... think it's to do with the rear tower & wishbones being different

Edit: It's to do with the front of hinge pins being a different height on the squared to the origional x6

not sure the new wishbones alter the anti-squat mind and my carbon spacers do have different holes in but there's 7 of them and 3 of them are different thicknesses and all have 2 holes in them.

As i bought this car second hand I am wondering how to work out the anti squat...?

Here we go this is from Dan Greenwood

The original 0 deg shim for the X6 is 3.8mm but this would give 1 deg pro squat on the new car as the difference in height of the front of the hinge pin means the actual squat is 1 deg below the value. So the 1 deg old shim gives true 0 deg on the squared and is 3.1mm. Personally I run 2 deg of squat usually which is therefore the 3 deg old shim.

There are only 5 different shims in the official shimz kit (0,1,2,3,4) so not sure about yours that have the same amount of holes in some!?

No spacers is 4 degrees, add the thinnest one for 3 degrees, change for next thickest for 2 degrees etc. etc.

Exactly right!

What ever amount of holes you have in the block take -1 off the amount!
