Are there any aftermarket K-Members like UPR, QA1, Team Z, etc... that would work with stock control arms, H&R lowering springs and Bilstein struts on a 1990 Fox Body? I'm currently running the stock k-member with H&R lowering springs and bilstein struts and have my car at a friends shop getting some things taken care of. One of them is couple of oil leaks and he recommended that it would be a good time to do a k-member swap but a little low on funds right now. So if I can save some money now and do the control arms and coil overs later down the road that would be better for me. I've been out of the fox body game for a long time. Any advice would be much appreciated.
