What is a Coilover?
A coilover is an automobile suspension device. The name coilover is an abbreviation of “coil over shock absorber”.
How To Adjust Coilovers
Many coilovers allow you to adjust the ride height in two ways: by compressing or uncompressing the spring by way of a pair of jam nuts at the spring perch(which will alter preload) or by threading the shock’s base up or down(which will alter shock travel).
Every spring should be subjected to at least some preload.
How low should you go on coilovers?
Usually drops this much will allow you to tuck the tires in the fender pretty deep. In most cases, expect coilovers to lower your vehicle from 0.5″ and go as low as 3.5″.
