I have a Tanabe front underbrace (2 point, part# TUB130F) that I took off my G37 Coupe becasue it started to rub after HFC installation. Posting it here becasue it is the same part for both G37 Coupe and '07+ Sedan. I didn't realize how well it worked until I removed it. It has a spot near each end where it rubbed against a bracket on the HFC. Other than those flaws it's in good shape. They can't be seen from underneath with the brace mounted. $98 new, asking $50 shipped.

And yes, I know

I'll post some actual photos when I get home this evening. Here's a vendor pic of the bar installed.


I have plenty of references as I'm a vendor on myg37.

 

Where did you notice the most improvement with it?

 

Sold!

 

sob haha

 

In the front.

Seriously, I looked at where it mounted when I installed it and thought it was useless because that's a pretty sturdy crossmember it's mounted to. But when I took it off, the front end felt a little looser generally (hard to quantify) and less straight line stability. I didn't notice any drop off in cornering to speak of.
