I've swapped out my e12 rear subframe for an e28 subframe. I'm also running a 380hp+ S38B38. I'd buy this now!!! I'm thinking I need bombproof!

This thread was from before my time on the forum... I'd love to be able to get one! Are they still available???
Thanks,
Pat
Hi Jonas. I'm in. But I want/need one sooner than later please let me know how much and when it can be delivered. It is a track car and I need something closer to bulletproof. Also attempting a run at SEMA 2016.
Can I get one
Vote for NEW GROUP BUY - i'd love one of these

I bought this and then strengthened it up for the Large Case LSD.
Worth buying.

I'd be tempted to buy one. Wish we'd put this together before SharkFest...
I’m interested if you can make it happen.

Perhaps I am wrong but GI Jonas made these up a few years ago ( I purchased one for my M6) and while you all are interested, I have not seen him involved in any of the recent posts. I have a feeling requests are falling on deaf ears here. I suggest someone send him a PM to see if he is still here and if he can get this going again.... they are worth it.

Here's mine installed. I also strengthened up the subframe.
There are some slight modifications as I run the e12 chassis and use a large case 3.73 LSD.

Those are sweet mounts. Wish I would've found this board years ago.
My excuse is "I'm old".
Damn, I need one of these. If this is unavailable, what is my next best option?
There should be sketches on this thread somewhere. The bolt holes in the earlier sketches were in the wrong location. You could take the later sketches and get a fabricator to make them up. That's an option. There are simply no off the shelf items available. I'd take my car as well.

Sorry guys!! This part of my life became little more than a distant memory for the past couple years. Life has been way too in the way of everything and Ive been working on other things in other departments to boot. I admit that I hav'nt even visited this forum in longer than I can remember and was shocked to see my thread near the top of the list. So look, my time is limited, but i am pleased to see the persistent interest in these quite honestly. I dont have the time to be on here promoting the mounts, however if you guys want to start getting the word out about another group buy, ill bite on this for another run!
I really dont think I can justify making this a go for less than 25 units. I do have some remaining center sections that are nearly done in a box, but for the most part I need to restart again. Go ahead and keep the thread alive and please speak up if you want one. I will make daily appearances from now on to keep track.
Also I very much apologize to all who's requests went unanswered, was never my intention to just drop of the earth.
Thanks Jonas.

God, its been so long now. I need to redo my research or wait for someone to chime in. Im pretty sure the answer is yes but I cant recall if the "to body" mounting area is different.

I had to modify for the e12 chassis and then modify again for the large case diff as its mounting point is off centre. Still, works fantastic in my car.

Go to my photos above.The bomb proof diff mount is brilliant. It could take well over 1000hp.
Anyone with an e12 chassis will need their diff out and crack inspections as the e12 chassis floor was week around the diff area. A bit like the E46 M3 boot floor cracking problems. I had huge cracks repaired and I stiffened up the floor prior to bolting Jona's BB-Diff Mount in. So a great replacement diff mount after checking your diff floor pan for cracks.

That looks perfect! I'd love to have that so I don't ever have to replace it. It's way too expensive to buy the crappy rubber piece with no poly options.
I am definitely in for one if we can get enough interested to make it happen. Has anyone started a list yet?
