The new Fairlady Z (RZ34) is a car that gets better the more you push it. The VR30DDTT twin-turbo V6, the rear-wheel drive layout, the manual gearbox option — it's an honest sports car in a world of driver-assist systems. But like any sports car, there are details that can be sharpened. The NISMO Titanium Tower Bar is one of them.

Let me give you the number that matters first: the NISMO titanium tower bar for the RZ34 weighs 0.96kg. The factory steel tower bar weighs 3.87kg. That's a reduction of 2.91kg — a 75% weight saving in the engine bay, up front, where reduced mass makes a real difference to steering feel and front-end responsiveness.

Why titanium specifically

You could make a lighter bar from other materials — aluminium, for instance. But NISMO chose pure titanium for a specific reason: it combines low mass with an inherent compliance and energy absorption that aluminium doesn't have. Titanium has a stiffness-to-flexibility ratio that filters road vibration more effectively, meaning you get chassis tightening without adding harshness to the steering feel.

For a car like the RZ34 that's already well set up from the factory, this is exactly what you want from an upgrade: improvement without compromise.

Pure titanium construction. Product weight 0.96kg. Fits all Fairlady Z RZ34 variants. Part number 54420-RSZ45, 198,000 yen including tax. Covered by NISMO's one-year guarantee.

If you're building out an RZ34 with genuine NISMO parts — whether that's suspension, exterior, or chassis reinforcement — this is the tower bar to run. Nothing in this price range from any other manufacturer matches the engineering pedigree behind a NISMO part.
