H&R TrackPro Suspension Kit (S550 Mustang)

Introduction If you've looked at the StreetPro package, using the standard springs in the H&R Street Performance kit and wanted better spring rates that were more balanced and tailored to track use, this is the kit for you. We swap out the H&R springs that are too soft up front  for our track tested 514 lb/in front and keeping the H&R 500 lb/in rear spring rates. This change in spring rate dramatically reduces brake dive and roll in corners vs any "lowering spring" offered for this chassis! This kit is built around the H&R monotube struts, shocks and ride height adjusters. We add front  Eibach springs that match the H&R parts, a pair of Vorshlag camber plates, and an option for our Vorshlag spherical rear shock mounts. A good percentage of S550 Mustang buyers are looking for a lower ride height and firmer spring rates and better damping, but don't want or need damping adjustments or a $5000 coilover kit. If you are reading this, you might be one of those folks. May
