Got my car nearly setup just having a problem with the rear stepping out as you come on the power after a corner, this is on the slippy floor part of the track (although that is most of the track

) my setup on the back at present is
0 degree camber
3 degree per side toe in
22mm ride height
5.5 turn spring
50 wt oil
kit piston
middle hole on rocker
any help or suggestions appreciated
