Upgrade suspension without lowering car

LaCross · 02-16-2015, 07:51 AM

I have a 135i M sport which already comes pretty low. Im very happy with the ride height. Is there a set of firmer shocks that would work well with the oem springs? Or springs that will keep the same height?

Koni Yellow, FSD or Bilstein B4

b6 i think -they are stiffer and for standart ride height.
b4 will be on same level, as oem shocks (or even worse)

Where are you getting your information? As far as I understand it the b4 and b6 shocks have the same internals except the piston and bump stops are shorter on the b6 to accommodate shorter springs.

You are absolutely right, I'm not used to referring to the touring struts as b4. I guess if there weren't ignorance on the Internet there wouldn't be entertainment for some.

I'm confused. I want to accomplish the same thing this spring and all the searches I did on this topic said either Koni Yellow or Bilstein HD. This is what tire rack shows for the Bilstein for 135i:

So is HD and B6 the same? or are they different?

thanks!

Yup, HD and B6 are the same. Definitely won't lower your car, perhaps very slightly the opposite. Have them paired w/ stock Sport Pkg. springs. Great ride.
