WTF w/ steel E38 rear sway bracket 'mod'? Iz wrong info on innwerbz?

[Jason5driver]

Wait, so the E36 M3 brackets are the same as the E38 brackets?
I was hoping to just swap in the E36 brackets, because I don't like how I sandwiched the bar with the E38 brackets...

Now they are listed as such yes. At least as far as I could find.

Problem solved, steel upgrade E39 brackets.

I have broken several OE rear brackets on my 2002 M5. I have watched the price go up on the OE bracket and still buy them but I am at the point where I keep one in hte glove box and check them often. I tried the E38 bracket and I didn't leave it on the car because of the rear bar binding. It would cause unpredictable oversteer (not good at all). The bracket, with it single bolt design (like the E38) flexes, it is really stressed while entering a driveway at an angle. If the bracket was steel, it could tolerate the bad design but making it out of aluminum and making it the same thickness, it flexes much more. Aluminum is 1/3 the stiffness of steel and it has much less fatigue life so the bracket needs to be three times stiffer to have a chance. Attaching it with two bolts would probably fix it too. Making it out of steel would fix it for sure. I found these on Ebay, they are steel and they fit perfectly using the stock bushings. Now I have three spare OE brackets but I doubt I will ever use them.

Where is it binding? I had the M5 bar on my car and then switched to the thicker Eibach bar. I haven’t experienced any binding using the steel E38 sway bar clamps.

If you disconnect it, it will be very difficult to move. The E38 bracket is made to hook in a raised pocket, the E39 actually seat on hte back side of the bracket so the hook or tab is longer. You can get the stock bolt even started. Besides smashing the busing, the bracket support is in a major bind and not properly aligned. I know, I bough a set and tried to install them. I reluctantly bought OE ones. Rear bar bind is a serious issue as it causes a stick/slip condition that will make any transition to roll unpredictable. We used to put delrin inserts in polyurethane sway bar bushing in our race cars because the bushings would stick/slip and cause all sorts of handling problems. I don't really care if you use the E38 brackets but I like to see as many M5's as possible survive so fix the binding issue. The brackets fit perfectly with the stock bushings. I could remove one and compare it to the E38, then you would b eable to see what am talking about. Let me know what you think.

You need both wheels off the ground to disconnect them, regardless of which clamps your using.
Guess I’m going to need a pic to see what your talking about as I don’t have any issues using the E38 brackets. They have been in my car for years.
