I have a MKIV GTI with KW Variant II coils, I went to lower the front back down from its winter height and the nuts are seized/jammed, I tried the first time Sat. night, cleaned the threads and doused the nuts with liquid wrench, could not get the helper nut to move, had a more experianced freind, (who is also the preivious owner who bought and installed the Coils) try it again tonight with me, we got the helper nut loose and moving-with the help of the floor jack pipe on the end of the coil wrench, it still took an insane amount of effort to turn the nut down the threads. Then we tried the upper nut with the spring on it, it will not move, we pretty much wrecked the spanner trying to get it to budge. We cleaned the threads good with a wire brush and lube. These nuts should not be that hard to move right? My friend said he could almost turn them by hand last fall? What are we doing wrong here? We tried Liquid wrench and some chain lube for a motorcycle, should we have greased the threads when we installed them? I must say for $1600 these things should work better than they do. Thanks for any help, I will be calling HPA in the morning
