I just installed a set of B14's on my '04 R53 yesterday.
Love the ride right out of the box.
Having been under the car today I happened to notice a nut and hex key bolt at the very bottom underneath the front strut/shock.

By any chance would this be a damping adjustment? Bilstein makes no reference to damping adjustability for the B14.



So I can't imagine or assume it should not be tampered with.(?)

Clarification is greatly appreciated.

 

I have no experience with these coilovers other than reading their product descriptions, but that doesn't look like an adjustment **** to me, it looks more like it's holding the strut together.

 

It is not an adjustment ****, its the mounting nut for the strut piston. The B14 front struts are inverted.

 

I also recently installed B14's on my R53.

It's the B16 set that has adjustable compression and/or rebound damping. That is the ~$800 difference in the price of the 2 sets. A price I could not justify for my needs at this time.

 

Well I kinda knew it wasn't a damping adjustment. Just wishful thinking that FCP may have sent me the wrong struts by mistake
@ghostwrench -Yeah, totally agree. 'couldn't find justification for +$$ for my dd either.

Thanks guys.
