zesus-3: I believe the white car has stock sport suspension. The convertible we just did the install in 45 minutes. If you have a spring compressor you can compress the spring on the car and remove the shock and spring. We left the spring compressed and took the top nut off. Removed the OEM top hat and installed the new one. Put back the top screw and reinstalled the shock and spring in the car. Then we removed the spring compressor.
