I know a bunch of you have put these in.First off I didn't need a jack to get them in.I pushed the lower a-arm up by hand and was able to get the nuts on the ball joints then tightened them up and if I try hard enough I can still spin the spring.I triple checked and the springs are correctly in there pockets.Is this normal?When the weight of the car is on them should I be OK.Car occasionally sees the track and would hate to see one come out on a launch.
Thanks,Scott

Lowering springs would always be shorter unless you were using a real soft setup. If you're worried about them coming unseated at the track use a travel limiter in your suspension.

I know from personal experience that I had to have a 215# person sit on my subframe so I could get enough threads on the upper ball joint to start the nut. I think I managed to get 3 threads showing with him sitting on the frame. You may have worn out lower control arms, but don`t quote me on it.

Are the bushings on your upper and lower control arms worn? Are the bolts securing your upper control arms tight?

Never loosened upper arm.Put poly bushings in about 3000 miles ago which was about 10 years back could they go bad from age.Car never sees weather
