What is this rusted out bar? I just bought a 08' G35x and am starting to clean it up but can't figure out what this is. It mounts behind the rear suspension and in front of the split in the exhaust, the tab in the center is what the rear splash guard bolts to. I know it's not the stabilizer bar.

 

Rear subframe brace
Rear subframe stay pin brace
Rear subframe stay

It's got a few names and nothing official from Nissan so you'll probably need to search for all 3 names, the AWD one is different and only has that single center mount point. The non-AWD ones have two mount points.

 

Thanks, Just found and bought a replacement.

 

OMG thats a rusty!!
Beats my rusty front subframe!

 

For anyone interested the part # is 55451-EG010-10229
