    Default Camaro leaf rear roll center

    Hunting more side bite.
    Will going to a taller lowering block help?
    Say going from 1" LR and 2" RR to 2" LR and 3" RR and resetting the ride heights by lowering the rear of the spring in the shackles to get the rear of the car back up.
    This should lower the rear r/c as it is half way between the rear end pad and the spring?

    easier to raise your lead in the rear of the car if this is an option, also make sure it is close to the rearend and not way out the back of the car.

    What are you percentages? Where is your weight located? and What springs are in your car? Why do you need more sidebite? Are you in a four wheel drift?

    Lead is already as high as I can get it, just below deck. No lead beyond 12" behind rear axle center line.
    51% left
    52% rear
    120lbs. of LR bite
    1100lf 1300 rf
    200lr 200rr
    3400lbs camaro with RC4 tires on 8" wheels.
    Car turns sideways just before entry and stays that way thoughout the corner killing exit speed. This is on a 4/10 mile fast cornered track.
    Removing left helped, but not enough.

    Looks like you may want to try some softer springs in the front ( I run a 850 and a 900) and more left side weight around 54% What is your cross % ? Also what are you ride heights?

    Lowering blocks make minimal change to RC in leafs.

    As Jason said lower both front springs; you cant get any weight transfer that heavy. That RF is not allowing the car to roll in the RR rear. I would run a 900 LF and 1000 RF. Run those springs with 5 shocks in the front.
    Make sure the RR is more inside ( closer to the frame) then the RF. Dry track, the RR should be close to the leaf.
    NO more than 3/8 rear steer on the rearend also. If you have some take it out and try it.
    Good luck.

    Softening the front springs really helped, had to go up on bite as the weaker RF took away forward drive. Thanks guys...
