So one of my rear springs decided to snap at the weekend. Not sure where/what to buy to replace. There are various advertised via EBay, but they all seem to say 'not suitable for M sport suspension'. I have 2.5si M Sport, so can anyone advise exactly what I need, and where is best to buy from?
Or do I just go to BMW for OEM springs?
