Nissan 370Z Z34.
The coilover guide.
Shop the coiloversSet your 370Z up for the roads and circuits you drive. Identify the body and original market, then choose the spring package, rear layout and damping controls that suit the car.
A shorter Z, with its own setup.
The 370Z packs a 3.7-litre V6 and rear-wheel drive into a shorter wheelbase than the 350Z. With wider aftermarket wheels, check inner suspension clearance as well as the outer arch gap. Usable travel and a measured alignment help the lowered car work on the surfaces you drive.
Start with a standard coupe, NISMO or Roadster application. Z34 is this generation; Z33 is the earlier 350Z and RZ34 identifies the later Nissan Z. For an imported Fairlady Z or a car with changed arms and mounting hardware, include those details in the fitment check.
The 370Z coupe arrived for the 2009 model year. Nissan shortened the wheelbase by 100mm compared with the 350Z and widened the body. The new 3.7-litre V6, compact cabin and boomerang-shaped lights made the Z34 a distinct car, even though the two generations share a familiar front-engine, rear-drive layout.
Nissan developed the Roadster alongside the coupe, with a folding fabric roof and its own rear body structure. It retained double-wishbone front and multi-link rear suspension. European 2011-model updates revised the dampers for local roads, so record the build date and original market when comparing the current car with an aftermarket specification.
The European NISMO joined the range in June 2013 as a manual coupe. Its chassis and aero package differed from the ordinary car. A later update, sold in Europe from September 2014, brought a revised front bumper and rear spoiler, along with further suspension changes. Identify the version and any replacement bodywork when checking ground clearance.
For a road car, decide how much travel and clearance you need before settling on a stance. A track project adds questions about tyres, operating weight and repeatable settings. Springs and dampers work alongside the existing joints, bushes and alignment adjustment; replacing tired parts can be as important as choosing the new kit.

FLEX Z VSP92-C1AA3 is the road-focused starting point for the listed UK Z34 application. Its twin-tube dampers have a combined 16-position damping adjustment. TEIN specifies rubber upper mounts and 12kgf/mm front, 10kgf/mm rear springs for this part. Start within its recommended lowering range, then check the car on the roads you actually use.

MONO SPORT GSP92-71AS3 pairs monotube dampers with 14kgf/mm front and 12kgf/mm rear springs in the UK Z34 row. Consider it when circuit work is part of the brief and you want an overhaulable damper. It retains a combined 16-position damping control; it does not add separate compression and rebound knobs.

AST 5300 RAC-N2009S is listed for the Z34 and provides rebound plus separate low- and high-speed compression adjustment. Those compression controls describe damper movement, not vehicle speed. Agree the spring and mounting package for the actual car, and plan reservoir installation with the fitter. Keep setup records so each change has a purpose.

Separate spring or true rear coilover?
On a standard Nissan 370Z Z34, the rear spring and shock absorber are mounted separately.
Layout only. Mounts and spring seats vary by kit.The factory Z34 rear spring sits between the body and its lower-link seat, beside a separate shock absorber. Nissan shows them as different assemblies in the workshop manual. An adjustable spring seat can retain this layout; the rear spring does not have to surround the damper for the kit to provide height adjustment.
BC lists D-30 for the ordinary arrangement and D-121 as rear integrated. A true rear kit places the spring around the damper, changing where the spring force enters the car. Confirm the correct mounts and any supporting work before ordering. The two layouts are different packages, not settings you switch between after fitting.
NISMO owners may also see a transverse rear performance damper named in Nissan documents. That chassis component is separate from the wheel shock absorber. Include it in the fitting discussion if hardware around it will change.
Understand height and preload
Set the height. Then measure the car.
Inspect the arms, joints, bushes and upper mounts before installation. Give the fitter the wheel widths, offsets, tyre sizes and spacer measurements, together with the intended ride height. The NISMO bumper and any added splitter need a ground-clearance check as well as tyre-to-arch clearance.
After the suspension settles at the agreed height, have the alignment measured and set. Keep the resulting figures with the damping settings. If the factory adjustment cannot reach the agreed target, discuss suitable arms or other correction parts with the fitter before buying them.
Wheels, tyres and arch clearance
A wider tyre or lower offset can reduce clearance even when the wheel diameter stays the same. Check inner clearance to suspension parts and outer clearance through steering and suspension movement. A static photograph of the arch gap cannot show those limits.
Springs and the rear layout
Compare the spring specification within the chosen layout. BC lists different rear rates for its separate-spring and rear-integrated Z34 packages; the spring acts at a different position. A larger spring-rate number alone cannot rank the resulting stiffness at the wheel.
Damping access and optional electronics
Plan how you will reach each adjuster once trim and other hardware are in place. The two UK TEIN Z34 rows indicate EDFC compatibility; the required controller, motors and installation work are additional checks. Electronic adjustment is not included merely because the coilover accepts it.
Track preparation and repeatable changes
For a car with a cage, removed interior or different tyres, specify the operating weight and intended circuit use before agreeing springs. Record the starting height, alignment and damping positions. Change one setting at a time and note what the driver experiences.
The current 370Z Z34 range.
Compare the controls and hardware included in each range.
The UK Z34 rows distinguish FLEX Z and MONO SPORT by spring rates and damper package. Both give a recommended 15–35mm reduction at each end for the listed application. Use the recommended range for the setup discussion; the larger maximum adjustment figures are not a recommended road height.
View TEIN 370Z Z34 kits
D-30 and rear-integrated D-121 have different rear arrangements. Their selectable BR, ER and ZX options must be checked for the actual mounts and supplied springs. Choose the layout with the fitter before selecting the series.
View BC Racing 370Z Z34 kits
The current Z34 application row names 5200 and 5300 Motorsport kits. Compare their independent damping controls and confirm the Z34-specific mounts. The generic family description includes camber plates where applicable; it does not establish that they are supplied for this double-wishbone front suspension.
View AST 370Z Z34 kits
The listed Z34 references cover Clubracer, two-way and three-way packages. Discuss reservoir placement, adjuster access and the spring/mount specification for the operating weight and tyres. A configurable competition car needs that detail before the part number becomes an order.

Questions about Nissan 370Z Z34 coilovers.
Check the details before choosing your kit.
Are 350Z, 370Z and the newer Nissan Z coilovers interchangeable?
Treat them as different applications. This guide covers the 370Z Z34. The earlier 350Z is Z33 and the later Nissan Z is RZ34. Match the exact manufacturer part number to the chassis, body, market and build date, including any changed mounting parts.
Do the coupe recommendations automatically fit a 370Z NISMO or Roadster?
Have those applications confirmed separately. The UK TEIN rows used here name Z34 without distinct NISMO or Roadster entries. Other-market records can differ in specification and part suffix. Give us the body, original market and build date so we can check the chosen package.
Does the 370Z use separate rear springs and shock absorbers?
Yes. Nissan places the rear coil spring on its lower-link seat, separate from the shock absorber. Kits can retain that arrangement with adjustable spring seats. A true rear coilover instead surrounds the damper with the spring and needs the correct supporting mounts and installation.
How low should I set the TEIN examples on a UK Z34?
The current UK FLEX Z and MONO SPORT rows each recommend 15–35mm lowering at the front and rear for their listed application. Start the fitting discussion within that range and check wheel clearance, travel and ground clearance on the actual car. The maximum adjustment range is not a target height.
What changes between FLEX Z and MONO SPORT for this car?
FLEX Z uses twin-tube dampers; MONO SPORT uses monotube dampers and supports overhaul and revalving. Their UK Z34 spring rates are 12/10kgf/mm and 14/12kgf/mm front/rear respectively. Both have a combined 16-position damping adjustment. The car, tyres and use decide which package is appropriate.
Can these TEIN Z34 kits use EDFC?
The current UK application rows indicate EDFC compatibility for VSP92-C1AA3 and GSP92-71AS3. Confirm the required motors, controller, fittings and adjuster clearance for the car. Those electronics and their installation are separate from the coilover kit.
Why does the NISMO manual mention another rear damper?
Nissan also identifies a transverse rear performance damper on the NISMO. It is a chassis component, distinct from the shock absorber controlling wheel movement. Tell the fitter which original chassis hardware remains when discussing suspension changes.
Is the most expensive kit the right one for track use?
Choose a package for the actual application and setup work. Independent compression and rebound controls can help a developed car, but they require a suitable spring specification and a repeatable adjustment plan. Price alone does not establish balance, lap time or suitability for road use.
Let’s talk suspension.
Identify your 370Z with the finder, then tell us the body, original market and current wheel setup. For NISMO, Roadster and converted cars, we can check the exact application before you choose a kit.
