Alright folks first post to the forum here. I've done a bit of searching and am looking to replace my front bilstein 4600 with the 5100's. I'm doing so cause I have a broken coil spring as well as 100k miles on my struts. So just makes sense to replace and upgrade it all. My question is. Has anyone used moog coil spring or the ac delco coil springs on these struts? I have read people didnt have the best luck with either of those. And looking at what other options might be out there. drive a 11 pro 4x. What coil springs have people used? Thanks for the help.
