The other dave was right. You'll need to take out the entire rear suspension and have it repaired with a new plate and weld. As a
former BMW owner I'm very familiar with this type of problem. They
weld a reinforsement plate over the defect. In the right hands it will
be better than new. Good luck.

 

Yea I talked with the engineer over at Comptech and he'd like to see the cracks welded and a reenforcement plate made of 1020 Steel welded in as well.

 

I was wondering where you can pickup one of those asr braces. Thanks.

From the information that I have gathered. A subframe tearout will indefinitely happen when using a larger swaybar. When will it happen you ask? Right now, maybe tomrrrow, a couple of years, or a decade from today. Just like a tootsie pop, "The world may never know." With the ASR/Comptech brace, it will only prolong the inevitable. A stiffer spring rate will also add days, months or even years to the life of the subframe. Thus, the driving condition will effect the subframe tremendously. As stated, he heard a pop going at a forty-five degree angle up a driveway. As you will figure out, this will put a tremdous load on the subframe. Pot holes, speed bumps, and any other anti-speeding obsticles will contribute to the tear-out. There is no other way to be safe but there is a way to be prepared. Reinforce the subframe with either an ASR or a comptech kit. Stiffer spring rates will help. Put some money away for a rainy day. And good luck.

 

Yea I already have changed my driving style. Instead of angling all wheels I only angle the front wheels then bring the rears as parallel as possible.

Maybe I should fix it up, get the asr brace and stock sway bar and call it a day.
