same here. same mileage.

just dropped diff for other work. no sign of fatigue/cracks yet. interior is stripped so the top is easy to keep an eye on, but I was worried about the TMS reinforcements/bottom.

So far, so good.

In for recommendations as well. I have plates but my M3 needs additional bracing.

This is my plan once I find cracks on my RACP, seems better than trying to weld plates/bars into the existing one and then finding other cracks that were missed.

With preexisting cracks I agree. But if a new panel is being installed, I think foaming it before the metalís been stressed at all should be enough to not have future worries.

Ya but what about 8 years later, surprise! I don't know, I see your logic, but I just would always want a plan b waiting. It's a shitty situation for all of us unfortunately- the never really knowing 100% what may happen in the future part :/

I've done quite a few of these at this point and I prefer the PS Design/Reddish plates and cmp auto trunk solution. I haven't installed any CMP plates but from a pure surface area coverage and weld length their plates should be superior as well.

I've installed a couple of the weld in and rivet in vince bars and I haven't been a fan. The CMP may have taken the idea from Vince but they improved the fit and finish for sure.

Personally anything visible from the interior is a non-starter for me.

Honestly it's just a looks and feel thing. If you hold both a vince and CMP in your hands there is zero chance you will choose the vince. The fit and finish is just superior on the CMP. The Vince just feels and looks flimsy in comparison and I will never install another rivet in option again. I do however like their front cups as they are the least intrusive option out there.

EDIT: I wanted to add that the vince and cmp serve the same purpose and the vince bar definitely gets the job done as it is designed. It's also quite a bit cheaper than the cmp so take that into account as well.

I had my entire RACP replaced a couple months ago. This was after getting the turner reinforcement. I would recommend making sure your RACP isn't tearing free before anything. If its repairable, cool, if not, you may as well start saving.

Once you've ensured your RACP is solid, I would go with the subframe foam + strut/vince bar.
