I have a new, never mounted, coil over set up. They have never been mounted. The springs are Eibach and the hardware appears to be Ireland Engineering. The springs and adjusters will fit over a 50MM strut housing but were bought for an E12 .$450 shipped CONUS. If any of you need any E28 suspension parts, I have a new set of Spax lowering springs. $280 shipped Conus
