Listed for: 1970-1973 Datsun 240Z (HS30)Fitment notes & questions

This is SF Racing's track-oriented coilover kit for the 1970-1973 Datsun 240Z (HS30): height-adjustable, 32-way damping and valving tuned for hard driving at the circuit or on back roads. This version is listed for RWD models.

1970-1973 Datsun 240Z setup details

Both ends use a true coilover layout, with the spring sitting on the damper body at every corner. Damper bodies are 52mm front and rear. It comes with 9 kg/mm (about 504 lb/in) springs up front and 7.3 kg/mm (about 409 lb/in) at the rear. Damping is 1-way: a single knob with 32 settings changes rebound and compression together, which keeps tuning quick. The front top mounts are aluminum with pillowball bushing. At the rear, the mounts are aluminum with pillowball bushing.

Key features

  • Monotube damper design for better heat control and fewer leaks
  • 32-level damping adjustment, rebound and compression combined on one adjuster
  • NOK seals and Italian IP damping oil (20W)
  • Built-in dust boots and bump stops
  • Bolt-on install with no modifications, unless the notes below say otherwise
  • Adjustable ride height, roughly 1 to 2.5 inches below factory per SF Racing, while keeping suspension travel
  • Independent lower mount adjustment keeps spring preload and damper travel where they should be when you change height
  • T6-6061 aluminum hardware (top mounts, perches and collars), anodized against corrosion
  • Zinc-plated shock bodies for rust protection
  • SAE9254 cold-wound springs

Important: Requires welding for installation. Welding required for installation.

Who it suits

Before you order: Datsun 240Z fitment and setup

Coilovers combine the spring and damper in one adjustable unit. That lets you choose your ride height on the Datsun 240Z and, on kits with damping adjustment, tune how firm it feels.

Fitment notes

  • Listed for: 1970-1973 Datsun 240Z (HS30).
  • Model years: 1970-1973. Check your car's year falls inside this range.
  • Chassis code HS30: parts for other chassis codes of the same model usually won't fit.
  • Factory adaptive dampers: if your car has electronic or adaptive suspension, check whether the listing covers it or needs a cancellation kit.
  • Specs, lead time and warranty come from SF Racing and can change. The details above this guide are the latest we have.

Plan the whole job

  • An alignment. Any change in ride height changes camber and toe. Set your final height first, then align.
  • Camber and toe adjustment. Bigger drops often need adjustable arms or camber plates to align properly. See alignment and camber kits.
  • Wheel and tire clearance. Check clearance at full lock and full compression, especially with wider wheels. Our ride height and wheel fitment calculator shows how much drop and offset change you are planning.
  • The right spring rate. Compare the rates listed here with what our spring rate calculator suggests for your car's weight and use.

Questions about Datsun 240Z coilovers

Will this fit my Datsun 240Z?
It is listed for the 1970-1973 Datsun 240Z (HS30). Check your year, model, drivetrain and chassis code against the product title. If anything is different, contact us and we will confirm fitment with the supplier before you order.
Do I need an alignment after installing coilovers?
Yes. Changing ride height changes camber and toe. Set your final height, let the suspension settle, then get the car aligned.
How low can I go?
It depends on the adjustment range the brand lists, your wheels and tires, and how you use the car. Most cars that are driven hard work best with a modest drop that leaves enough suspension travel.
Where do specs and warranty details come from?
From SF Racing. We sell parts from several brands and suppliers, and each one sets its own specs, lead times and warranty terms. The product details above are the latest we have.
