Diff Braces?

SalM · 11-09-2017, 08:01 PM

Anybody running diff braces in our cars? Lock down the differential to eliminate some wheel hop could help save our axles big time. Did a quick search didnt find much on this topic.

Anybody running a diff brace ? Where can we get one ?

I am designing one... available shortly

Awesome ! How we looking on cost ?

allmotor_2000 · 11-13-2017, 01:49 PM

It's made from a solid billet piece... so expensive. I need to test-fit and then will put up a post for people who may want to purchase.

Do you have the capability to replace the circular section in your brace around the bolt that goes through the rubber bushing in the stock piece? Perhaps with Delrin or something with at least some slight deformability?

In pictures of those braces that have failed, the mounting bolts have also been broken. Your brace appears unbreakable, will that put more load on those bolts, or serve to save them?

In regards to SalM's question, I don't believe wheel hop in an IRS will be solved with this brace. I'm willing to be proved wrong.

Yes option for solid and bushing as well - TBD on material. Also bolts will be class 12.9.

Excellent. For a DD it might be important. Even for serious dragstrip use some give might be helpful. Are there other rubber mounting points that should use more solid bushings to complement your support?

allmotor_2000 · 11-13-2017, 04:52 PM

The front diff mounts have rubber bushings so there will be some give. I believe one of the reasons the rear gives is due to excessive flex on that rear bushing. If it were rigid that flex goes away but who knows where it will break next!

You will show us in the next months! Thanks for your willingness to pave the way for the rest of us.

How many stock differential mounts have broke ?

BMWAUDIO · 01-02-2018, 09:27 PM

2 On my car .
first one broke when Allmotor had the car and it was replaced just before i bought the car and that one broke about 6 months later

would designing a metal bushing to replace the rubber one make sense instead of the entire mount?

Yes, that's the plan. The metal version was for fitment

My take on steeve13's question was that he wants to retain the stock cast brace and replace the rubber in it with a metal bushing to surround the mounting bolt. I hope he'll chime in with his intent, but if that was it I don't think the stock casting would hold up.

allmotor_2000 · 01-16-2018, 12:53 PM

Stock casting is weak.. it cracks very easily

Michaelmabill · 01-16-2018, 01:51 PM

Wher Can i buy this?

V8munro · 01-18-2018, 03:34 AM

I have MT's and looking to 1/4 this year again on them. Is there any work around getting the oem diff braced before yours goes into production and what part is usually breaking the rear?

JuniorM3 · 01-23-2018, 08:11 AM

I NEED ONE ASAP!!!

Nice job!

keep us posted
