Designed with the most discerning of drivers in mind, QA1s Double Adjustable Pro Coil systems give you the flexibility to seemleslly adjust ride height and your dampening. These systems all include QA1s high travel springs which are made of a smaller wire diameter and feature less coils than a comparable spring of the same rate and length for more useable travel and decreased unsprung mass. This not only allows for more useable ride height adjustment and useable stroke, but also allows your dampers to do their job a little easier from the decreased weight. QA1 offers these systems with multiple spring rate and length options as well to help you get a coilover package that works for the weight, use, and desired ride height of your vehicle. To further aid you in tayloring your suspension to your specific needs, these coilovers also feature 2 Way independent rebound and compression adjustment so that you can tune suspension movement in both directions, allowing you to maximize ride, traction, and balance simultaneously with little compromise in any department.
