Do the Hipermax R Coilovers for R35 fit every GT-R model year?

HKS USA lists the kit for the R35 Nissan GT-R with the VR38DETT from 2008 to 2025. HKS does not publish separate fitment data for NISMO or other special versions, so owners of those cars should confirm with Bulletproof Automotive before ordering.

Where should I start with the damping settings?

HKS reports its best Fuji Speedway test result on ADVAN A052 tires with 12 clicks at the front and 8 clicks at the rear. That is a reasonable starting point for track use on the GT-R, and softer settings can be chosen for road driving or rough surfaces.

Is the kit too stiff for street use?

No, not for most owners. HKS built the Hipermax R line for drivers focused on track performance who still want comfort in everyday use, and the 30-step adjuster leaves room to soften the car for the road. Expect more road feel and noise from the spherical bearing upper mounts than from rubber mounts.

How low does the kit sit compared with a stock GT-R?

As delivered, HKS sets the Hipermax R Coilovers for R35 12mm below stock height at the front and 16mm below at the rear. The front adjusts to 58mm below stock and the rear to 60mm below. HKS warns that body or arm contact can occur even inside the adjustable range.

Can HKS change the spring rates on this kit?

Yes. HKS lists factory spring rate changes as available front and rear for the Hipermax R Coilovers for R35, although it does not publish a recommended range for the GT-R. The upper mounts cannot be changed before shipping, so the kit always arrives with spherical bearing mounts.

Description

HKS Hipermax R Coilovers for R35 Nissan GT-R

The HKS Hipermax R Coilovers for R35 bring fully adjustable single-tube dampers to the VR38DETT powered, all-wheel-drive Nissan GT-R, a car with enough weight and speed to expose any weakness in a coilover. 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 GT-R that sees circuit days on sticky tires, this is a serious tool. An owner who only wants a lower stance on the street will get far more adjustment than they will use.

Development and Testing

HKS did the setting work at Fuji Speedway on ADVAN A052 tires and reports its best result with the dampers at 12 clicks front and 8 clicks rear. Treat that as a starting point for a US car rather than a fixed recipe.

Features

Single-tube dampers with a large-diameter piston, in a normal layout front and rear
Helper springs at both axles
Dual PVS (Dual Preload Valve System) valving carried over from the HIPERMAX S
Shock-body length adjustable construction with height-adjustable lower brackets
Spherical bearing upper mounts front and rear, 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: 196 N/mm (20 kgf/mm)
Spring rate, rear: 157 N/mm (16 kgf/mm)
Helper spring rate: 19.8 N/mm front and rear

Ride height as delivered, front: 12mm below stock (adjustable from 2mm to 58mm below stock)

Applications

Nissan GT-R: R35 | 2008-2025 | VR38DETT

Notes

HKS USA lists fitment from 2008 to 2025, while HKS Japan lists the R35 from late 2007 production with no end date
HKS does not break out fitment for NISMO or other special R35 versions, so confirm before ordering
The HKS HIPERMAX S Coilover Kit for R35 Nissan GT-R (80330-AN001) is the HIPERMAX S kit for the same car, without the three parts exclusive to the Hipermax R Coilovers for R35
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
HKS covers Hipermax R for 2 years or 40,000 km, and damper oil leakage or other problems caused by lowering below the HKS delivered height can void that warranty
Install the Hipermax R Coilovers for R35 at a shop familiar with the GT-R and follow with a four-wheel alignment

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.
