My 06 had subframe cracks at 60K miles. There's no hiding from the issue in my opinion.

I'm now reinforced by Redish

No matter the year, every owner should keep reinforcement in mind. Not that bad to fix and even better to do a preventative reinforcement. Most cars, unless they are garage queens, will likely need diff and subframe bushing replacement now anyway.

Just bought an 06 and this thread title got me excited for a moment, spreading hope to my heart but I knew better after reading all the SF threads. I just hit 100k and will be doing the Redish plates this month.

Do you have a plan to look for secondary failure of the RACP separating? Did your shop also do extra seam welding while doing the plates?

My loose plan is to do the plates/bushings now then do a Vince type bar if/when the RACP starts to go. I just don't know if it will be too late by then. Or should I bit the bullet and do them both at the same time? it's probably another $1000 minimum on top of the $2000 i'm already shelling out. That 1000 can go towards the Vanos or bearings that I also need to prevent from failing.

I like the Vince bar very much. I feel it addresses the fundamental weaknesses. It would make sense to install it if dropping the subframe for plates (assuming cracks are present). Unfortunately for me, it came along just after I did the plates. So I'm in the wait and see if plates are enough category. And I have not heard of any plated RACP failures, so I am optimistic. No seam cracks were observed when the plates went in, so no welding done.

Verts need the reinforcement just as much as Coupes, yeah?

So they say. There are threads out there that give detail on it, bottom line is that verts need it too.

My sedan had the RACP replaced by the dealer (subletted out to one of the best BMW body shops in the state), and I still had to fix a couple cracks and popped spot welds while installing Reddish plates and a Vincebar.

Reinforcement should always be done, no matter the year.

What about 2005 sedans that have already had the airbags replaced?





Just kidding


Thanks guys. I still need to do this.
