Thanks to advice from other forumers, I went ahead & installed KW V2's on my E90 lately. Manage to get a good deal from someone, but the price in the market + installation is anywhere between 7.2k to 7.4k. If you want a lower ride & also want to change the shocks...then go for the KW's. Its not better than the other brands, but its adjustable on the hieght & rebound rate, made in Germany. The ride is comfortable, almost better than stock, the difference is that your ride is firmer (depending on your settings) and handling is much, much improved! I think the KW's are probably the best compromise between comfort & performance in the market today. But if you have RFT's, then you'll still get a pretty bumpy ride when you go over imperfections.
