Just for info - New OEM Shock Manufacturer

E90Fleet · 06-11-2006, 05:51 AM

Just to keep everyone informed

Asof June 2006 Production"
The OEM shock manufacturer for E90 built with "Normal" or "Sport suspension" ( not M Sport Suspension ) has changed from BOGE/SACHS to BILSTEIN.

No changes were made to the specs, just the manufacturer

BMW0 · 06-11-2006, 08:20 AM

Bilstein is more well known and seems a bit more sportier though, my shocks do very well as is. I guess BOGE/SACHS is a pretty good manufacturer. If specs stay the same then it all fall down to quality and longterm performance. Thanks for the insightful info as usual E90Fleet

What's the difference between "Sport suspension" and "M Sport Suspension", as both lower the distance to the ground by 15 mm?

JSpira · 06-11-2006, 08:26 AM

Dear Fleet,

Any other June changes? Did they start with a new PROGMAN version in June?

It would be great if we could chart the running changes that have occurred in the E90 since SOP.

Thanks for the information.

M Sport has stiffer springs and different shocks

No other real changes I can think of.

Would have to wait till I got lots of time to make a running changes chart

Hey Fleet, thanks for the info, is there any particular reason why BMW switched company?

nmulax · 06-12-2006, 11:48 AM

So am I correct to assume my E90 will have Bilstein components? It went into production on Saturday the 10th of June. I know the specs are the same, and really, 99.99% of the driver (myself included) will not know the difference; but as BMW0 said, "Bilstein is more well know".

shragon · 06-12-2006, 11:59 AM

bilstein is more well known due to their aftermarket presence, but in reality, i believe sachs-boge is a much larger company. they build many suspension components that are original equipment on cars. http://www.sachs-boge.de/?weiter=1

since the new bilsteins are built to bmw's specs, they going to be very very similar to the ones they replaced.

Anything stiffer than what I have now and I will have to superglue the rearview mirror.

Mark · 06-12-2006, 06:03 PM

Wow, very interesting. Bilstein has long made equipment that is at OEM quality, performance and comfort, so as a long time Bilstein user/fan this is great news! Maybee they can offer adjustable suspensions as OEM equipment in the future (yea right, just wishful thinking

ward · 06-12-2006, 06:04 PM

I LOVE bilsteins!!!

maybe this will help the M division in the future!

E90Fleet · 06-13-2006, 05:41 AM

Its nothing new
Bilstein has for many many years supplied BMW with shocks for certain models. ( E30, E36 ect ect )

Im not 100% shure, but I think the M Sport shocks have always been Bilstein

Mine is very smooth and grips the road like you wont believe

stressdoc · 11-15-2006, 12:11 PM

I wonder if the rates on the M pack springs would help compensate in switching from rft to non-rft. Any source for specific data on the springs?

E90Fleet · 11-15-2006, 12:26 PM

I have no data on the spring technical details

therealm3 · 11-15-2006, 05:09 PM

Wouldn't it be the other way around? With more mass on the arm you would need a stiffer spring, right? So with less mass (non-rft) a softer spring would ride the same? Any engineers out there? Its been too long since college for me.

I think that's exactly right.
If anything, I'll bet this change is being made to further support the changeover to run-flat tires.
And of course, a good reason to continue price increases...

There are multiple variables at play here. The unsprung weight will be reduced if the non-rfts are lighter. Hence the dampening of the momentum of the wheel mass could be reduced (but not spring rates). The more significant issue with rfts is sidewall stiffness and compromised ride quality. To reduce the impact of bumps some magic with dampening, bushings, and spring rates is required with rfts. I plan to opt for tougher bushings and tighter/lower springs when I switch to 19" non-rfts.

GregL · 11-15-2006, 06:57 PM

Does this mean that if my shocks are ever changed by the dealer for whatever reason in the future, then Bilsteins will be installed?

therealm3 · 11-15-2006, 08:57 PM

I hear ya. You are looking at it from the perspective that the super stiff sidewalls necessitated a slight softer dampening and spring rate to maintain a decent ride. I was looking at it more from the perspective of force generated by larger mass moving in a given direction and a stiffer spring needed to resist that force. Based on the marketing docs BMW has put out, I bet you are on the right track. Maybe we could talk to a complete tuner like Dinan and ask them what their approach to suspension is when removing the run flats and adding 19's?

On topic – Bilsteins are great shocks. I am pretty sure my E30 M3 had them as OE. Now it has Bilstein sports that are 9 years old and still ride great.
