These are properly stacked with the tallest main spring possible to provide the most stroke. Some spring rate spiking is also reduced with this setup.

BMW radial thrust bearings(top) and Swift thrust sheets(bottom) are used so corner balancing is possible even with the full weight of the vehicle on the tires.

This is exclusively from HP Autowerks, Inc. No other rear coilover spring setup offers you this function. Period! I am sure others will copy this soon...Some have tried and failed(you know who you are!).
