Stock suspension drag racers step in please.

Remember to try one change at a time.I would start with some slicks for traction,from there I would add adjustable rear shocks(never mentioned what you have in the rear now).You might need to swap your HD leafs to either SS springs or Caltracs with mono leaf setup.It all depends on how much track time you,ll be seeing.You need to get a base time trial to move forward with changes.JMO
