My 6MT Coupe isn't due for several months, but I'm already looking at mods! This forum will no doubt be a hazard to my wallet.

I've searched the site and did not see any comments on the various subframe braces:

Has anyone had any experience with them? I've read about the front tower brace being generally unavailable, but how about the rear brace? I see that there are aftermarket ones available, but would the Z brace fit?

I used a strut tower brace on my Miata and it made a noticeable difference. I realize a G35 isn't a Miata, but I am a big believer in chassis strength.

 

Yes. The front GT spec brace can be really difficult to install because the front suspension at that point doesn't exactly like to unbolt. The rear stuff is not a problem on the coupe.
