This kit allows the user to change spring rates at home or the track in minutes, without disconnecting the lower control arm 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 BMW 1M coilover kits on the market today, you must unload the spring tension or use troublesome tools to adjust the rear ride height, but not ours!
What is in the kit:
*HPA Rear Ride Height Adjusters(widest height range adjustment on the market with this design)
*BMW Sealed Radial Thrust Bearings(used on the top of the main spring)
*Swift Main and Helper springs
*Swift Thrust Sheets(use at the lower portion of the spring, between the helper and the control arm)
