First your car should handle alot better once set-up properly on your new set-up station. Without knowing track conditions and layout I can make afew suggestions.
- more front toe-out(turn in harder&more agressively)
- thicker rear diff silicone(drive harder into first portion of turn)
- add front camber(alittle goes a long way)
- lower front ride height in relation to rear
The list can go on and on but this is a good starting point.
Remember your always going to have to slow a bit in the turns, so dont try to overdrive the car. Also what shore tires are you running?
