Known issue

370Z rear diff bushes

That thud or thunk on and off the throttle? On a hard-driven Z34 it's almost always the rear diff bushes. The factory rubber cracks under load and lets the diff move around.

Symptoms

  • Thud or thunk on and off the throttle
  • Clunk shifting between drive and coast
  • Knock over bumps or mid-corner
  • Oil weeping around the diff

FAQ

Common questions

Can you tune the VQ37VHR reliably?
Yes. The VQ37 is a strong engine. We've built plenty of high-power 370Zs that still daily drive — when the parts and tune are right.
What ECU tuning do you use?
EcuTek. Full calibration control of the VQ37VHR with proper data logging.
Do you work on Nismo models?
Yes. The Nismo has slightly different ECU calibrations but we tune them regularly.
Can I start with RZ Stage 1 and upgrade later?
Yes. Stage 1 parts (intake, cats, tune) all carry over to Stage 2. You're not wasting money by starting small.
How long will my car be with you?
RZ Stage 1: 2 days. RZ Stage 2: 3-4 days due to cooling and header install. RZ Stage 3: 1-2 weeks. Servicing usually same day. We'll confirm timing when you book.
