Review Bell Raceworks rear differential brace

Yes. The rear end is very floppy stock due to soft rubber bushings in and around the rear subframe. And while the urethane bushings do a lot to eradicate this floppiness, there is still some movement. See this Z1 video
of stock vs urethane bushings on the diff and subframe of a 370Z. Even after urethane, you can see the diff wiggle about with throttle changes. This brace will remove most of the remaining flop, leaving only suspension inputs to cause the subframe to wiggle around the subframe mounts.

I have a pair of Z1 polyurethane motor mounts sitting in the corner of my office, waiting for an April 2019 install. Now I have the dilemma whether or not to have this brace mounted at the same time, or to split the mod installs.
On the one hand, doing them both at the same time is a single shop visit, and guarantees maximum smiles all at once.
On the other hand, doing them separately let's me assess the value of each.

Will that work with the stock differential cover?

That's what I'm going to find out. You mentioned Jon at Z1 told you it would work with the stock unit so I'm going to put it to the test and find out. Figure, that will take the guessing out of the equation as to which brace to get if plans of a high capacity differential cover is on someone's build sheet.

I've heard some advantages of this mod, now what are some disadvantages? Also, does anyone have an idea of what a shop would charge to have this installed? Thinking about getting this, but I have to wait a while since I just purchased some FI RHFC's.

Check out the group buy thread, the manufacturer just posted some info. It is bolt on so you can do it or a shop should be an hour charge i guess. The only disadvantage is there will be more NVH (noise vibration harshness) since there's no slop between the parts now.

Anyway, that's what I'm thinking when thinking about the install. But I'm going to have plenty of other-people input right here before getting into it, which is cool.
Someone needs to go to the top post and thank the OP for this thread.

I could see a shop charging an hour of lift time for the 3-point brace, maybe even two if they're really cautious and it's a tight fit. But AFAIK, the 4-point brace is a direct bolt-on, without any complications. In other words, the only point in finding a shop would be lift-access and tools for a 10 minute job with a ratchet. And in other-other-words, the 4-point brace should be an easy DIY.

At least, that's the talk. We'll find out over the next few weeks as people get their orders and do their installs.
Dude... in the span of one day, 16 people signed up for the group buy. That's pretty cool, and in no small part due to your review.

Hi guys,
I commented on the group buy thread but wanted to know what I'm looking for in terms of feel when/if I buy this. I drive an xS coupe 7AT so would benefits if any would I gain and how would I feel this changes? I know the power lag is due to the computer system but where in my driving will I see the most benefits?
Best regards!
