R/C Anonymous,
It pushes because it has too much rear toe-in making the car too stable in the rear. The A6113 rear hub will reduce it by 1 degree and the off-set center balls can reduce it by another 1 degree. That should help free up the rear end a bit. Another thing you can try after these adjustment is putting a shim (from the A6511 shim kit) underneath the front rear suspension ball mounts (just a 0.5mm can have a pretty dramatic affect) that should make the front dive even harder into the turns. Give those a try
