QUICK CHANGE REAR SUBFRAME FOR NISSAN 370Z/400Z

The FRESH X Z34 Quick Change Rear Subframe is built for one thing – keeping your Z alive when you’re throwing 1000+ hp sideways. Designed for Nissan 370Z / 400Z, this setup lets you drop in a Bulldog or Winters quick change and get back on track fast.

Forget solid-mounting your diff and shaking the car apart – we run polyurethane bushings instead. That means way less shock going into your axles and driveshafts, smoother vibes through the chassis, and a drivetrain that’ll last way longer even when you’re clutch-kicking every corner.

Every unit is jig-built so the diff sits dead straight. Welds are locked in on a fixture, everything CNC-cut, then finished in a black powder coat that’ll take abuse season after season. Service is easy – four big bolts, straight shot from the bottom, swap the diff in minutes with an impact.

Yeah, you’ll need to trim the rear crossmember a bit, but that’s how we get the diff sitting at the right height for slammed coilover setups. Run it with our solid subframe bushings (sold separately) for max rigidity, while the diff still floats just enough to soak up the hits.

This is the subframe you want if you’re serious about drifting, drag launches, or time attack – strong, serviceable, and built by racers who break parts so you don’t have to.
