I have a 2010 M-Sport 335i in automatic. If I ever make big power, say FBO + inlets and E85, will this brace help with traction? Will the drive feel different in any way, positive or negative?

Thanks

The only reason for the brace/lockdown is to control wheel hop. So if your wheels are losing traction due to hop, then it'll help. Otherwise not so much.

I'm putting in an LSD soon, next few weeks, and I went ahead and ordered a lockdown kit with it. Enough people with similar setups have had hop issues, that it is cheap insurance on an issue I'm likely to have.

I'd say yes and a big yea for the money of them as well. They are cheap insurance on braking a driveshaft from pinion deflection as well as absolutely help with wheel hop!

We have a seller on here that makes a nice affordable unit. Check out the fs adds

I just ordered this braket for my e92 manual.I will post here after I mount it.
Actual I have a lot of hops when I try to launch faster.
Hope this bracket will fix it.

How long you can get away w/o one depends on your definition of "big power" & what you do w/ the car. Dig racing puts a lot more stress on things than roll racing.

My thoughts as well; cheap insurance.

I never had wheel hop, but I noticed a difference after I got a diff lockdown. Even just FBO my car would be very 'wavy' for lack of a better word at WOT. It was not very confidence inspiring driving at high speeds. While I'm sure bushings would also help, the diff lockdown cured 99% of the issue in my car, and even now with MMPs it no longer has that rear end waviness.

I make mid 400whp and have never experienced wheel hop whatsoever. I'm not sure what people are doing to have experienced this, but I don't think at fbo a lockdown bracket is very necessary unless you just want to spend money for "insurance" or peace of mind as others have said.

A diff lock-down brace (I have one) is so popular because it's easy to install and provides an insane markup for the handful of people bending the $5 worth of steel.

The bracket does nothing if you have proper diff bushings installed. Money is best spent on said bushings (the price of a bracket gets you 1/2 way there) if you do th elabor yourself. Also, locking the diff down won't help wheel-hop much if you don't have adequate shocks with rebound dialed in...

What bushings would you recommend to get an acceptable amount of movement? The only thing I have back there are the akg black bushings. I think they are black, whatever the more streetable version is.
