What aftermarket part is rattling my teeth out?

Hi all / 

 

Before I start removing bits thought I’d ask here in the hope someone can save me some time! 
 
At 5k +when accelerating hard the entire car buzzes and vibrates. The same way in every gear. It has some drivetrain mods, and I imagine they all are contributing, but wondered if one in particular is known to introduce lots of NVH? 

Lightened single pass flywheel 
Z1 Solid Subframe Inserts

Torque Solution Gearbox Mounts

Poly diff bushings (these were originally solid, I’d changed them to poly).
 

This is my second 350Z, the first was a standard road car, so I know what they’re like stock. 
 

Ultimately it’s a track car, so it’s not the end of the world, I’m just curious if anyone else has any input.
 

Many thanks -
