Last night we (My buddy Lou and I) installed the Eibach pro kit 3530.140. It is specifically designed for a convertible! We also added the energy suspension spring isolators in the front and back, as well as Maximum Motorsports weight jacker lower control arms MMRLCA-102. The control arms have the poly bushings on both ends.
The installation went pretty straight forward for the rear. With the car up in the air supported by jack stands on the subframe connectors, we removed the sway bar. Next was the nuts for the front and rear pivot bolts. Then we used the jack to support the control arm and removed the shock bolt. We then removed the control arm pivot bolt at the rear axle side and lowered the control arm down slowly with the jack. The spring came along with it. Then we removed the spring and took out the chassis pivot bolt to remove the hotchkins solid lower control arm. We did the same thing for the other side as well. Then we installed the new control arm with the perches adjusted all the way down, along with the new spring and isolators and torqued to 80 ft lbs. We had to modify the bracket for the emergency brake cable (bent it upwards to relieve some tension) and the ABS sensor bracket needed to be removed from the bottom of the ebrake and a new 1/4inch hole drilled to move the bracket towards the back so the sensor wire could be mounted and not stretched.
The front was also interesting. with the car in the air, we removed the caliper (not the bracket) and hung it out of the way. Then we removed the sway bar end link nuts and moved / rotated the sway bar out of the way. Then we supported the front lower control arm with a jack and removed the strut bolts. This allowed the control arm to be lowered down slowly by the jack. Once we removed the jack we were able to pry out the spring. The driver side spring was broken - about 4 inches of coil at the end had broken off - some time ago too, judging by the rust. After cleaning out the spring perches we installed the isolators on the top of the spring, and the round one onto the spring at the bottom. Then we rotated the spring so that it would fit in the lower control arm. We had to pry the spring a bit to get it into the perch. Then we got the jack underneath the control arm and raised it up to get the strut mount bolts installed and torqued. We re-installed the brakes, sway bar end links and finally the wheels. The last thing was to torque the wheel lugs and lower the car off the jack stands.
with the car on the ground, the rear end sat really low. I needed to adjust the spring perches upwards a bit, which was done with a 1/2 inch ratchet.
