Does anyone make anything for G37s, that's a stock tower brace that also ties into the cowl as well? I see that 370Z has one from factory, wondering if it's possible to use 370Z parts, or perhaps get something aftermarket.

 

There was a thread a while ago where a member was going to try to do some kind of bracket fabrication to use the Nismo Z brace, but don't think it ever got past the planning stage
They really are a nice setup too.

 

Any idea what's different about the Z and G underhood. I figured they are more or less on the same platform, running the same engine, a lot of parts seem to be interchangeable. A 3 point brace would probably help out with some of that squeeking that happens in corners, stiffen up the cowl area.

 

The 3-point Z brace mounts above the towers at points only the Z have (you can google some pictures and compare the Z and G to see what I am talking about). As for the rear mounting points I am not sure if the G has them, but I know they are different between a LHD Z and a RHD one; working off that info and the fact the side mounting points are only existent on the Z I would presume the G lacks the back mounting point as well. You would need to fab mounting point for all three point most likely for it to work.

All that said I could be wrong as I've never had a Z 3-point in my had and held it too the G. It would be nice to have a 3-point but the cost to pay-off might be negligible when a front Nismo/Yamaha damper and good 2-point tower brace might accomplish the same for half the price.

 

The whole idea behind the 3 point brace is to add rigidity around cowl area. How would a damper help that? As far as I know, that's supposed to make the engine run smoother, and as far as I can tell, it runs smooth as silk.

 

It's a chassis damper, not an engine damper. It doesn't add much rigidity, but what it does in spades is help control chassis harmonics. The more rigid you make the front the more prone to vibration it will become. The Nismo damper will help counter that. If your goal is to get rid of squeaking it will help a good deal. It will also help tie the front suspension together and give you a much smoother and quiet ride up front.

 

By more rigid the front, you mean suspension right?

I'm not familiar with a chassis damper. In the past I've used subframe connectors, and roll cage to make the cars stiffer. Got a link?

 

Probably your most informative source: Yamaha Performance Damper

Their original design was for the snowmobile use, which is were I first got exposed to them. They make a world of difference on that platform. Nissan started using them on their Nismo edition 350 and 370z. They have been on the Skylines as far back as the R32 I believe. I know Subi uses them as well, not sure about anyone else yet as I've never looked into it. They make a noticeable difference on our cars. I have UR lower 4-point brace. It stiffened up the front some. When I installed the Nismo damper it made the most noticeable improvement to ride quality, bump management, and noise reduction. But that's just my personal experience, I am sure experiences will vary based on car, build, and butts.

And by more rigid in the front I mean the entire front: chassis and suspension. The chassis being able to flex as it does absorbs a lot of vibration. Stiffening it up makes it more prone to vibrating. Like a tuning fork.

 

As for cowl noises, there are a couple of threads on that. There is a simple and inexpensive fix.
an awesome thing. I really want one myself. But as stated above, there is no center mount point, and it sounds like the side points don't line up with the strut towers anyway. This would be a totally custom mod session. Even if you can get the strut tower mounts right, creating a *useful* center cowl mount would be quite a challenge. Hard to say it would be worth the effort. And you wouldn't want to have the first hard corner transfer the load into your windshield.
