Default Best subframe repair options as of July 2018?

So as I expected, my subframe does indeed have cracks, possibly rather extensive. My plan was to get a VinceBar (along with whatever other products he recommends), and have Coinage install them. But Vince ran into some personal issues I believe and I haven't really heard much from him since my last correspondence with him in April or so. He seems like a great guy with a lot of thought behind is products... but I really can't wait much longer.

So what's the best piece of kit I can actually buy? Less money is good, but let's say absolutely no more than $5k after labor.

I can't say much more than just my personal experience, but I have Turner kit installed about 10K miles ago, and its been solid so far. FWIW.

If you don't already have reinforcement plates, Redish plates have been the 'Gold-Standard' here.

To reach Vince, checkout his FB page, where he is more active (if you haven't already):
https://www.facebook.com/PPRnDnews
vincent@practicalperformance.se

Another option (No personal experience outside of reading his posts on here) is CMP Design (Australian) -- Very similar to the VinceBar. Same idea. By the looks, this option likely weighs a bit more and is not totally hidden like the VinceBar...but something to consider, especially if you can't get ahold of Vince.
http://www.m3forum.net/m3forum/showthread.php?t=565038

Honestly, it wouldn't be hard to get a local metal fab shop to fabricate up a "VinceBar". Would be much cheaper done locally (especially since you avoid international shipping).


Really surprised your RACP wasn't already reinforced!

Ha yeah, most people are. It's a job that goes beyond what I can DIY, and I just didn't have the money or time to deal with it in the past. Not that 3rd year is particularly good for either of those points, but well, it needs to be done. Original plan was to just drop my car off at Coinage's for a week while studying for step 1.

I avoid facebook as much as I can. I guess I'll try sending him an email.

I have a first run epoxy Vince bar sitting in my basement that I’ve been putting off getting installed. Waiting until some good local shops get some experience with the install.

I’m also in the back of my mind wondering if cutting up the car is really necessary and whether Redish plates and foam would be more than adequate. AFAIK we don’t have any cases where Redish plates have failed.

Yeah I was going to go for the weld-in version myself. I personally think epoxy is superior, but no one wants to touch it, and I can't DIY this.

I'll probably need things welded regardless at this point, so whatever.

How extensive is your damage? are you considering RACP replacement? for 5 grand or so you can pull off a RACP replacement with some good reinforcements. thats what i did and thats what I would recommend for a piece of mind.

Not fully assessed yet. At least one crack is visible with the subframe in place, so I'm expecting the damage to be pretty bad, possibly enough to necessitate replacement.

Check in with Matt to see if he has any VinceBars at his shop. I know eventually he wants to start keeping some in stock.
