: Did you go for the Eibach Pro-kit or the Sportlines?
: Im thinking of getting a set of springs just to lower a car a bit and to get rid of that gap you were talking about. Wasn't looking to go drastic on the upgrade (cost and ride quality) so was thinking about the Racing Dynamics ones from Bavarian Auto. Any opinions?
Brian-To be honest, I don't know which Eibach spring set my mechanic installed-the part number on my invoice is BM.2063.140 (cost $280.00). I'm not as knowledgeable as some of the gearheads on this board-you might want to ask Ryan who responded below and is pretty knowlegeable about suspension modifications. What I have learned is that you need to be very careful about just changing springs. Shorter springs generally are stiffer (they need to be or you could bottom out the car). Given that they are stiffer (and you WILL feel the difference), you 'll need shocks and struts that are matched to the spring rates- to soften the harsher ride. That's not to say that your OEM shocks/struts won't work with new springs, but you need to check that out carefully- preferably by a good mechanic you can trust who has done a fair share of suspension work on BMWs.
I'd also be careful about stiffer sway bars. See Ryan's comments as well. As much as we're all looking for inexpensive ways to stoke our Zs,
unfortunately this stuff doesn't come cheap.
