Hi guys, as we all know e46 do have rear subframe crack problem, but what do you guys do? Replace the whole rear subframe at bmw, or use those plates and strength it?

Thanks

had full floor done on both cars,done on bmw warranty,, but think that’s over now. But also bmw refused to repair full floor for a second time on one car but plated it,so I guess they think that is ok also. :whistle:

Thanks, what about other guys? What are he differences between replacing the whole rear vs those aftermarket plates. I have had the car for 9 years now, I will probabaly keep it for much longer.
What would you guys suggest? Do it at bmw or plates?
Thanks

As long as the repair you have also has the sandwiched area resin filled, then it is all much of a muchness.

The BMW repair removes the entire area and replaces with new, so effectively the repair is undetectable (if done correctly), where the plates are visible. So it depends which is more important to you.

If I remember correctly NZ M3 gave a good explanation using a Coke can why plating did not work. This is going back some time so I could be completely wrong.
Would need to go back through old threads

Vincebar plus the Vince plate. If you havent heard of them search on M3F or go here:

Plating on it’s own does not give a lasting repair, nether will replacing the whole carrier panel. It’s the resin injection that makes the difference. As long as this is done either repair works well.

Even the resin injection won't be as good as of a solution than the vincebar. I'll post a link later to show how the bar works and the thought process behind it.

Perhaps but just how far do you want to go? Redish have a number of videos reviewing repairs performed a number of years ago now and since exposed to heavy track use. All have stood up fine. Vincebar might be better but you’re into deminishing returns.

True. I have the plates and I'll be doing the vincebar epoxy method sometime this year.

yep Gregor , seems that either full floor or plate inc resins is just a repair, when the car gets used looks like they will go again :whistle: gesss we just have to face it e46 boot floor is a bummer,, when it breaks “again” looks like we just have get on with it and fix it again, :banghead: ... suppose its part of the fun running a e 46 m,,,,must check the mileage when second fix was done , garage queens needn’t worry
