I have searched and read through a *lot* of posts on springs (H&R, Eibach) and coilovers (KW V1, v3, TC Kline etc) for 335xi's, and they all seem to recommend getting rid of runflats to preserve ride quality. I would like to keep my runflats (I know the ride is harsh with RFTs but I don't want to give up the safety of the RFTs, or any trunk room for a spare).

I am looking for suspension mods - springs, or coilovers that retain, or improve upon, stock ride quality, while improving handling to rival or come close to my previous bmws (330zhp, 540 sport), or a 335i with ZSP and stock RFTs. Any thoughts would be much appreciated!
