Track Guys! HPA Quick Change Rear Spring Kit for E9x M3
Change rear spings seconds, without disconnecting the lower control arm or dampers and without performing another wheel alignment as long as the ride height remains the same.
This kit not only allows you to change your springs very quickly, it also allows you to adjust the ride height of the vehicle with the springs installed. YES! With the springs installed. No need to remove the springs! Most E82/9X none M or M coilover kits on the market today, you must unload the spring tension to adjust the rear ride height or use spanner wrenches, but not ours!
This kit will work with oem or aftermarket rear dampers.
What is in the kit:
HPA Rear Ride Height Adjusters(Hard anodized)
BMW Sealed Radial Thrust Bearings(used on the top of the main spring)
Swift Main(your choice of rates) and Helper springs(with couplers)
Swift Thrust Sheets(use at the lower portion of the spring, between the helper and the control arm)
