Your mileage may vary, depending on what tracks you run.
No rear bar.
Some sort of adjustable bar up front, I have a Speedway Engineering splined bar.
Depending on if your shocks will handle the rate, 450 lb springs up front (some guys run up to 500 here in SeDiv), and 275-300 in the rear. You may have to compromise the rate if they overpower your shocks, or have the shocks revalved if possible.
