Been running the car for the past few months on high bite black carpet.
Still testing and trying different things but so far this has been my fastest setup.

I did mod the rear hubs by flipping them upside down.
I have 2 identical setups on both cars - one normal rear hubs and one flipped.
Flipping them gave me the same rotational feel I always felt on Mi9's
Picked up 2tenths on my average and the rear is very stable.

Need a 12mm countersunk screw for the hub side and a 8mm grub screw loctite into the steering arm.
Flip them and use the same shims - I started with 2.5mm shims on the steering knuckle.
