Here we go.
My class is more of a prostock class, but I will ask anyways.
I run a rocket camaro stub 3 link rear.
3/8 mile semi banked tacky track.

We have to use 5" coils on the rear 18" from the center line of the rearend. Springs must be verticle, no coil over eliminators, j bar to the left side of the chassis, rubber snubber 3rd link with a 9010 shock, (must all be mounted behind the drivers cockpit.)
I am putting a new rear in and I was wondering what you guys think for Spring palcement? Bar Angles, J bar height, 3rd link angle and 9010 shock angle.

This is the rule package from the track:

Cars with rear coil spring suspension must have spring placement no closer than 18" to the centerline of the differential. Coil springs must be mounted vertical, no angle mounting allowed. Underslung chassis allowed. Complete chassis, suspension and steering must be steel "only". No aluminum suspension parts.
NO floating brakes, NO lift bars, NO torque rods, NO four bar rear suspension, NO bird cages, NO torsion bar suspension.
No upper third links or shocks or snubbers to be allowed to extend past backrest of driver’s seat.
