Larger Sway bar advice
Looking for any advice on upgraded sway bars to compensate of my larger 17" 090 BBS staggered wheels.
My stock setup is 19mm front and 16mm rear.
IE has some http://www.iemotorsport.com/bmw/item/e28swaybars.html
25mm front
19mm rear
And UUC has some

27mm front
22mm Rear
Seems pretty aggressive.

Re: Larger Sway bar advice
You may actually have 15.5mm on the rear! The 16mm rear is the US M6 set up, I believe.
From my experience, you'll need to weld in different mounts for the larger bars: I had clearance issues even with the US spec M6 22mm front. I had the 16mm rear and the car did handle very well indeed.
Real OEM shows a stock M635 Euro set up to be 25mm front and 18mm rear, like (some of the) E28 M5s, but I'd like to find out if any M635s actually had this set up. The E28 M5s with the thicker arbs had softer boge shocks rather than Bilstein.

Re: Larger Sway bar advice
I went with the IE sway bars on LOCUTUS. Needed to do some minor bracket welding to get the correct fit but no biggy. Have not run the car yet. Which reminds me, I have to crack on with my project, D'Oh.

Re: Larger Sway bar advice
You should take a look at this thread.
viewtopic.php?f=17&t=22504&hilit=sway+bar
We had some real good discussion about the effects of bar changes. Since I run staggered wheels, sticking with the 22mm front, and upgrading the rear sounded good. Installing the 18mm in the rear has worked out really well for me.

Re: Larger Sway bar advice
Any one selling at 18mm rear, i think that's where I want to go.
I plan on reinforcing the sway bar connections

Re: Larger Sway bar advice
Jose, true dat
Note for Carl, you are referring to sway bars that are available for the E12 chassis, not E28 based
I have the same sizes, but from Korman Autoworks, 28mm front and 22mm rear
And while it's true that no additional welding or strengthening is "required", my Dinan adjustable camber rear subframe did come with reinforced mounting brackets for the rear bar

Re: Larger Sway bar advice
when i upgraded the sway bars on my e24 , the welds broke away so i had to reinforce them 2 times.

Re: Larger Sway bar advice
Definetly upgrade the rear with staggered. If u don’t have one already also install the rear strut brace.
