Rear sway bar bracket: Stronger OEM part found

Having just realised that my left rear sway bar bracket had broken off, I was about to get the very well made (but expensive) Beastpower brackets but thanks to a tip from member Frits (www.performance-shop-geel.be) I found out that there is actually a stronger OEM part available

The E36 M3 one is identical but made in STEEL rather than the flimsy aluminium of the E39.

The part number I have is 33 50 6 779 734, though I can't find this one on realoem, but it does pop up here: Support Bracket for Sway Bar Mounting Bushing - RM European Auto Parts

Think this would also be the same as this one # 31351124995 RealOEM.COM * BMW E36 M3 STABILIZER, REAR but no guarantee that this is the same as the # 33 50 6 779 734 that I know works and is made of steel.

Replaced both my brackets for very little €

nice tip, thanks! I will be looking into upgrading these next time they break. Bought the car a year ago and it already had new ones fitted, so no point in changing them yet!

cheers

rassi did you actually install them yet...or just ordered them? Can you confirm they definately fit?

I wonder if they ship to !!!

edit: nevermind they're a US company! I suppose these aren't the same as the ones get from a BMW dealer for the E39 M5?

The non-M5 E39 brackets are also steel and probably less brittle than the aluminum ones.

Did the E36 have an aluminum sub-frame like our E39s? If not, you might not want a steel bracket against the aluminum. I think the reason they used an aluminum bracket in the first place was because of the issues with mixing materials (corrosion?).

Maybe somebody on here with a better understanding of this can chime in here?

I just wish that BMW had used a sturdier aluminum bracket or that the Beastpower ones were cheaper.

u prolly have a point. i'd bet there's something that would prevent corrosion though...a lubricant/grease or a piece of gasket material could be cut to fit.

Steel plus aluminum are a well-known galvanic couple. Google it. I personally would not use steel brackets on an aluminum frame member.

"Is it the sounds that make a BMW a BMW? A BMW is designed to be heard, felt, experienced. So our engines sing. Our steering talks back. And we insist on offering manual transmissions in nearly all our models for drivers who crave them. The result is an almost telepathic oneness with the car. Just as surely as you can hear a BMW, a BMW hears you."

So what kind of bolts do you use in aluminum?

Here's one google result:
Myths About Aluminum Body Tubs

1. There is one common myth about aluminum body tubs: Where aluminum and steel meet, electrolysis will occur and weaken the metals. It is scientifically true that electrolysis will occur between different metals, but it's only a significant factor in marine construction where the metals are immersed in water over a long period of time. These conditions simply don't occur on a vehicle. The fact is, it's not going to happen in a motor vehicle with an aluminum body. Think about the ways aluminum and steel have been successfully used together for many years. Most aircraft, for example, combine aluminum and steel. In automobiles, the legendary Shelby AC Cobra has an aluminum body and a steel chassis. Chevrolet's new Corvette, the new Audi A8 (see AutoWeek Sept. 2, 2002 issue), the new 2003 Jaguar XJ8 sports an all aluminum body (see AutoWeek Dec. 23, 2002 issue), and even the noble Bentleys and Rolls Royces of today, (see AutoWeek April 21, 2003 for the new Aluminum Rolls Royce Phantom), and yesteryear, have been crafted of aluminum and steel in happy combination. The Ferrari Modena 360, Acura NXS, and Aston Martin Vanquish all use aluminum to enhance vehicle performance. The auto industry is becoming "bullish" on aluminunm and it's use for body parts. In summary, don't worry about electrolysis. It occurs, but so slowly and minutely that it's almost like watching the wind erode the Great Pyramids.

plus like I said...just grease it all up a bit...the grease will put a barrier between all the dissimilar metals.
