The Sport spring position is a pain in the backside. BMW only sell the rears in pairs. And I hadn't realised they were on back order too. That's not to mention they are twice the price of Eibachs.
I made various investigations and enquiries about a year ago for alternative -15mm sources. I can't find anyone who makes them. I even went to several spring manufacturers (all seem to be in Sheffield no suprise) and none were interested despite advertising they'll make any spring.
So if I get the chance to buy Sport springs I do. I think I currently have, as acquired - 1 complete set, 1 pair of rears, 1 set missing a front spring and 1 odd front spring. So 2.5 complete sets which is the result of 1 years worth of trawling around.
