Loosen the 14mm nuts that hold the top perch, but don't completely remove them yet. This allows you to remove the bottom bolts easily without having the entire spring and shock assembly fall on you.

Disconnect the brake line bracket and the 14mm nut that clamps the bottom of the shock. After removing the bottom of the shock from the fork, remove the loosened 14mm nuts on top and take out the entire assembly.

Using a spring compressor, remove the factory upper spring perch, dust sleeve, bump stop and all the washers. Then slide the plastic alignment sleeves and the threaded aluminum sleeve onto the shock. Trim any excess plastic from the alignment sleeve.

Slide the main spring on the coilover assembly. Make sure you use the correct main spring (the springs are marked front and rear). Add the middle spring alignment perch and the keeper spring. The keeper spring helps to ensure contact at full extension of the shock and also adds a progressive rate quality to the ride under full compression of the shock.

Replace the factory bump stop washer followed by the included billet spring perch. Because the springs are of a slightly smaller diameter, the perch is used in conjunction with the factory perch to keep the spring centered under the constant compression and rebound motions.

Re-install the complete coilover assembly on the car. Now would be a good time to note the height of the spring perch (by counting exposed threads). This will make it easier to fine-tune the car once it is lowered on the ground. Repeat for the other corners of the car.

As you can see, the Circuit Pro springs are shorter than the OEM springs. This allows for a greater range of height adjustability over a kit with only threaded perches or a shock with adjustable perch height.

After installing all four corners and putting the car back on the ground, measure the distance from the center of the wheel to the point of the wheel well directly above it. Be sure to release the parking brake before taking any measurements. Using the supplied spanner wrenches, adjust the larger spring perch until you reach the desired ride height. Then, lock the perch in place by tightening the smaller perch against it. Remember to check for proper camber and caster to get the proper tire-to-road contact.
