Help Setup Buggy For Track

[DRIFT_BUGGY]

Anyone here got experience with setting up buggies for racing?
Im looking at racing my BL 8ight at the club and have never setup a car for racing as I usually just muck around with them or race against mates (nothing serious).
Only things I have changed since the Race Roller setup is 5000wt front diff - 10000wt centre diff - 55 piston and 35wt oil (i put 35 in as I didn't have 40) front shocks.
The buggy seems alright to drive but has a few issues. The rear diff fluid is 2000wt and when I accelerate hard the back tires seem to balloon fair bit. It also likes to spin around when driving hard out of a turn. I was flying down the main straight today and hit a little bump which made the front end go down which made the rear go up and over/flip. I also noticed today that the inside of the front tires (mainly the right) has been chewed out abit.
The setup below is the roller setup. The changes I have done have been added as red.
