Things You Will Need
- Floor jack
- Jack stands
- Socket set
Doing the Front Wheels
Here's how to install the coil overs on the front of the car.
Step 1. Raise the Vehicle Safely
On a level surface, raise the vehicle and place it on jack stands. Choose the right places for your jack stands (see below).
Step 2. Remove the Front Wheels
Next proceed to removing the front wheels. With the wheels off, support the lower control arm with the floor jack, putting some small tension on it.
Step 3. Loosen the Bolts on Your Stock Shocks
Drill the upper rivets that that support the upper shock plate in place. Now, loosen the upper bolts that hold your stock shocks but do not remove them just yet.
Step 4. Remove Other Components
Remove the brake caliper and secure it out of the way. Next, remove the ABS bracket, the two lower shock bolts, the three upper strut bars, and finally the shock. Remember to keep tension on the lower control arm using your floor jack. Finally, remove the sway bar end link.
Step 5. Release Tension on the Lower Control Arm
With the sway bar end link out of the way, you can now begin to release tension on the lower control arm gently. Keep doing so until you have enough space to remove the spring.
Step 6. Mount the Spindle
Loosely install the SR coil over using the 3 top-hat nuts that came with your kit. Now begin to raise the the lower control arm with the floor jack so that you can mount the the spindle to the lower strut mount. Make sure to use the spacers that came with your kit when mounting the spindle.
Side note: when adjusting the ride height, spin the strut assembly in and out of the lower strut mount. Do not base your ride height off of the springs.

Step 7. Reinstall Components
Make sure that all your bolts are tightened properly and re-install everything in reverse order. Make sure that both your ride heights match on each side as that will ensure a more comfortable ride.
Also, professional alignment is recommended after installation in order to prevent poor handling and premature tire wear.
Doing the Rear Wheels
Install the coil overs on the rear wheels using the steps below.
Repeat step 1 of the removal process for the front.
Step 2. Remove the Lower Shock Mounting Bolt
Remove the lower shock mounting bolt. Keep in mind that you may need to jack the rear up and down a few times in order to get the bolt out more easily.
Step 3. Access Upper Shock Mount Nut
Move the inner trunk liner out of the way in order to be able to access the upper shock mount nut. Once removed, go ahead and remove the shock.
Step 4. Prepare to Lower the Rear Axle
Remove the brake line bracket so that you can lower the rear axle without putting any unnecessary strain on the brake line. If you remove the quad shock you should be able to lower the axle much further.
Step 5. Remove the Factory Spring and Bushing
Lower the axle carefully and remove the factory spring along with the factory bushing.
Step 6. Assemble the New Spring
Use the factory rubber isolator and stack the new rear springs that came in your kit as shown in the image below.
The threaded lower mount, 2 locking collars, plastic spring isolator, spring, and the factory rubber isolator is what is shown in the image. Make sure to assemble them in that exact order.
Step 7. Raise the Axle
After the spring is installed, raise the axle just enough so that the springs are barely making contact with the upper perch on both sides.
Step 8. Install the Shock
Carefully install the shock through the upper shock mount.
The dashed line on the picture represents the shock mount. Above the line is where the trunk would be positioned.
Step 9. Re-Install the Lower Mount Bolts
With the springs making just enough contact with the upper perch and the upper shock, thread the shock body into the lower shock housing until the lower mounting holes line up with the lower axle bracket. Now, go ahead and re-install the lower mounted bolts. With the suspension loaded you can proceed to tighten down the lower mount bolt.
Step 10. Double-Check Your Work
Make sure that all the locking collars are correctly tightened on your shocks and struts. Once that is done you can adjust as needed in order to achieve your desired ride height.
Professional alignment is highly suggested after installation to prevent poor handling, and premature tire wear.
