I agree with TRF415boy, running Kick-Up will give allot more turn inn and can cause the rear end to step out!!
Also, running too much camber change in the rear will upset the balance, understeers on power and oversteers off power!!
I am running 2mm washer under the link on the innside and only 0.5mm on the outside. This gives a nice balance and makes the rear end much more controllable.
If you have problems with the car it is always a good idea to go back to the kit setting. This setup works very good and is always a good starting point
