Unfortunately, not as universal as you expect.

Have ordered a reconstruction of my BMW 1 Series E87 This spring compressor. In the original springs, it fits well, albeit with a lot of fumbling. Unfortunately, he is not to be used on my built H & R race suspension with 60mm race springs, as you have no chance to get into the narrow spaces between the turns. At various coilovers, it could also lead to this problem. The most common Tieferlegungsfedern should be feasible.

The processing and so on looks OK and enstspricht expected.
