There are two different kinds of coilovers that we offer; partially threaded coilovers and fully threaded coilovers. Read on to learn how to adjust each below.
Partially threaded coilovers raise and lower the car by raising or lowering the height of the spring on the coilovers. With partially threaded coilovers like the one shown, to raise the car, you will turn the collars up the shock body and to lower you will turn the collars down the shock body.
To adjust the coilovers, first, unlock collar B by taking your spanner wrench and turn it clock-wise. Once loose, spin collar B by hand down the length of the coilover. You will then use the spanner wrench to turn collar A clockwise to lower and counter-clockwise to raise the car. Once you have the perches adjusted to where you want it, spin collar B back up against collar A and use both provided spanner wrenches to lock the collars against each other. To lock, turn collar B counter-clockwise and collar A clockwise.
Fully threaded coilovers have independent ride height adjustment and spring pre-load adjustment. To adjust the ride height of a fully threaded kit, unlock collar C by using the supplied spanner wrench by turning the wrench counter-clockwise. Once collar C is loose, spin the lower spindle mount up or down the length of the coilover. To raise the car, you will lengthen the coilover, to lower the car; you will shorten the length of the coilover.
You can also adjust the ride height without having to unbolt the lower spindle mount by turning collar A or B but make sure that before doing so, that collars A and B are tightened against each other. Once collar C is loose, you will turn collar B counter-clockwise to raise the car or you will turn collar A clockwise to lower the car. Once the ride height is right where you want it, you will then tighten collar C against the lower spindle mount.
For coilovers that offer camber adjustment, you will loosen the four allen head bolts on the top of the coilover then adjust the coilover inwards or outwards. To make the camber more negative, you will adjust the coilover inwards towards the inside of the engine bay. To make the camber more positive, you will move the coilover towards the outside of the vehicle. Keep in mind, the more negative or positive camber that you run may result in increased tire wear.
For our Primo coilovers, to adjust the damping to be softer, turn the adjusting knob counter clock-wise. To make the damping stiffer, turn the adjusting knob clock-wise.
