Have not tried cutting the rear arms down 2mm to adjust the wheel base. If anything I would want to increase the wheelbase to transfer more weight forward in this chassis. For carpet use putting more weight forward makes it much easier to drive.
In front the middle location makes the car easiest to drive. By using 2mm the front end only gains .25deg of camber sometimes I use 3mm for 0deg camber gain if the traction really comes up (prevent traction roll).
Rear I used the most inside hole as it keeps the rear end planted through twisty chicanes. Have tried all sorts of shims and always seem to go back to 0mm inside and outside as best. Do you have a preferred rear setup?
Currently use 0.5mm shim under FR as it prevents the car from falling over the front shocks under breaking and also to calm down the steering when the traction really comes up at the end of the night.
Have tried putting 0.5mm under the RR and it makes the rear end feel less planted getting into the corner. I tried this idea after seeing it on marco's setup sheet.
