Who has an e91 on Stock suspension? Need measurement

NiNeTyOne · 02-05-2018, 07:26 PM

I need a couple measurements. Ideally a car in North America.

Absolute center of front hub to the fender edge (at top), same for the rear. Both with the car level with no unusual loading (i.e. empty).

For the fronts I'd like the measurements right and left.

Thanks in advance! I need to calculate the proper end link length from where my springs have settled. Cheers.

I'll get this in the next few days.

Much appreciated!

Once I have this I will post optimal swaybar link lengths for e91's running Eibach Pro spring sets PN E10-20-014-10-22 (which is the correct kit for the e91 xDrive and can be sourced from Europe).

it's cold and there's 6 inches of snow outside, so not today.

maybe tomorrow, for sure the weekend.

14 inches front
13 1\2 inches rear
Same on both sides. Stock suspension at 123k miles.

Great, thanks.

That means for an xDrive car on the correct Eibach kit (from Europe) the correct adjustable links from Turner for the xDrive are:

TSU9912135 370.00mm - 385.00mm

You would want them at about 375mm to have the same bar geometry once lowered up front by 34mm.

FYI - Turner has these links on sale at the moment for $129...that's $30 lower than the regular price.

I've got these and a B12 kit on order from Germany. I have a similar set-up on my E46 RWD touring and it is perfect for my needs. Should be a nice combo for a daily.

Did you ever come up with an answer for this?

I'm a bit confused about the different length end links though, with the car lowered, wouldnt the whole bar just rotate up from where it was and still function the same way? The arm length hasnt changed at all.

nsjames · 08-13-2018, 08:23 AM

you will break end links because now they can't move the bar. As it rotates further up you reach the top of the circle and rather than having vertical movement you only have horizontal movement. End links try to push against the bar, the bar cannot travel vertically, stuff breaks.

makes sense - I was having trouble visualizing it.
