Hello all, new to this forum. I just picked up a Canadian market 11/90 build M5, bk05790. It has already been converted to traditional rear suspension with koni yellows and h&r sport springs. The h&r springs ride rougher than I expect of an M5, having come from an e46 M3, and it gives the car a very hotrod rake that I don’t like. My question; is there any non sls springs that retain the factory height and a softer ride? Were there m tech package e34’s without sls that have a comparable spring? Is there a spacer or some kit to use the factory M5 springs without sls? I’ve heard good things about bavauto springs, they lower a non M 30mm front and rear, so that would lower an M5 10mm?
