So iv just bought some Teins Advanced Coil overs for my MK3 MX5 and had a garage install them due to fractured springs and what not. Yesterday I went to change the height adjustment and the front two had no issues what so ever, managed to slam them and everything worked fine. The rears however are being weird. The adjustment collars do spin however they seem to spin in place, no movement up or down, as if they aren't sat on the thread correctly. Has anyone else had this issue? what can I do to fix it? Edit: Healthy dose of WD40 and a wire brush got it moving
