Are the Hipermax R Coilovers for Z34 comfortable enough for daily driving?

Yes, for most owners. HKS set the kit up at Fuji Speedway on ADVAN A052 tires and recommends 8 clicks front and rear, with a setting 2 clicks down matched for a more comfortable ride over long distances. The spherical bearing upper mounts do pass more road noise into the cabin than rubber mounts.

Do the Hipermax R Coilovers for Z34 fit the 370Z Nismo and Roadster?

HKS USA lists this kit for the Z34 Nissan 370Z with the VQ37VHR from 2009 to 2020 and does not break out the Nismo or Roadster versions separately. Owners of those models should confirm fitment with Bulletproof Automotive before ordering, because HKS does not publish separate application data for them.

Will this kit fit the newer Nissan Z?

No. This part number covers the Z34 370Z only. HKS catalogs a different Hipermax R kit, part number 80310-AN007, for the RZ34 Nissan Z with the twin-turbo VR30DDTT. Bulletproof Automotive carries the HIPERMAX S Coilover Kit for RZ34 Nissan Z for owners of the newer car.

How low does the kit sit compared with a stock 370Z?

As delivered, HKS sets the kit 20mm below stock height at the front and 19mm below at the rear. The front adjusts from stock height to 30mm lower and the rear from 1mm to 56mm lower. HKS recommends the delivered setting and warns that body or arm contact can occur even inside the adjustable range.

How does the Hipermax R compare with the HIPERMAX S for the 370Z?

The Hipermax R Coilovers for Z34 keep the HIPERMAX S single-tube dampers, Dual PVS valving and 30-step adjustment, then add three parts exclusive to the R line: SRF damper oil, LVS high-strength springs and an upper spring retainer. HKS aims the R at owners who put track performance first. Bulletproof Automotive carries both kits for the Z34.

What warranty and service does HKS offer on this kit?

HKS covers the Hipermax R for 2 years or 40,000 km, roughly 24,850 miles, and offers overhauls so worn dampers can be rebuilt. HKS can also fit different springs at its factory before shipping, within 20 N/mm of the standard rates, although the upper mounts cannot be changed.

Description

HKS Hipermax R Coilovers for Z34 Nissan 370Z

The HKS Hipermax R Coilovers for Z34 give the VQ37VHR powered, rear-drive Nissan 370Z a firmer and more controllable platform for owners who split their time between back roads and circuit days. Hipermax R builds on the HIPERMAX S damper and adds three parts found only on the R line: SRF damper oil, LVS high-strength springs and an upper spring retainer. For a 370Z that only needs a lower stance, the HIPERMAX S kit is the simpler choice; for a car that sees laps, the R earns its place.

Features

Single-tube dampers with a large-diameter piston for stable damping force
Dual PVS (Dual Preload Valve System) valving carried over from the HIPERMAX S
WR Needle damping adjuster, so the same 370Z can run soft on the drive to the track and firmer once there
Shock-body length adjustable construction with height-adjustable lower brackets front and rear
Coilover layout at the front and a separate spring and damper at the rear, following the factory Z34 rear suspension
Helper springs at both axles, with a directly wound 65mm inner diameter main spring at the rear
Spherical bearing upper mounts at both axles, supplied as standard with no rubber mount option before shipping
Upper Spring Retainer, exclusive to Hipermax R, keeps the damper axis and spring load line aligned for less friction
SRF Super Response Fluid, a high-viscosity damper oil that resists heat sag
LVS Low Vibration Springs wound from 210k-grade wire, with a shorter wire length that saves weight and sharpens steering response
PNE coating that stops parts sticking from rust and reduces the effort needed to adjust ride height

Specifications

Spring rate, front: 157 N/mm (16 kgf/mm)
Spring rate, rear: 177 N/mm (18 kgf/mm)
Helper spring rate: 41.4 N/mm front, 19.8 N/mm rear
Spring length: 200mm front, 170mm rear, both straight
Ride height as delivered, front: 20mm below stock (adjustable from stock height to 30mm below)
Ride height as delivered, rear: 19mm below stock (adjustable from 1mm to 56mm below stock)
Damping adjustment: 30 steps front and rear
Factory spring rate change: Available front and rear, within 20 N/mm (2 kgf/mm) of standard
Shipping weight: 27.9 kg (61.5 lb)

Applications

Nissan 370Z: Z34 | 2009-2020 | VQ37

Notes

This kit fits the Z34 370Z only, and the later RZ34 Nissan Z takes a separate Hipermax R kit, part number 80310-AN007
The HKS HIPERMAX S Coilover Kit for Z34 Nissan 370Z (80330-AN009) is the HIPERMAX S kit for the same car, without the three parts exclusive to the Hipermax R Coilovers for Z34
HKS warns that the lowest ride height may not be road legal and that body or arm contact can occur even inside the adjustable range
Damper oil leakage or other problems caused by setting the car below the HKS delivered height are excluded from the HKS warranty
Professional installation and a full alignment are recommended after fitting the Hipermax R Coilovers for Z34

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
