Is the Drag Coilover Kit for BNR32 suitable for street or circuit driving?

No. HKS designed this kit for drag racing and asks owners to take care on public roads. The soft rear spring and rear helper are chosen for stroke and traction off the line, so an R32 used for circuit or road driving is better served by the HKS HIPERMAX S Coilover Kit for BNR32.

Why is the rear spring so much softer than the front?

HKS selects the springs and helpers for the Drag Coilover Kit for BNR32 to keep enough rear stroke and traction for drag racing. It pairs an 88 N/mm front spring with a 59 N/mm rear spring and a 19.8 N/mm rear helper, while retaining front traction so the all-wheel-drive car changes attitude less at launch.

How low does the kit sit compared with a stock R32?

As delivered, HKS sets the kit 34mm below stock height at the front and 19mm below at the rear. The front adjusts down to 68mm below stock and the rear to 41mm below. HKS warns that the lowest setting may not be road legal and that problems caused by running below the factory height void the warranty.

Is the damping adjustable?

Yes. Each damper has 30 steps of damping adjustment front and rear, which lets a racer tune how the GT-R transfers weight at launch. Keep a record of settings, track conditions and tire pressures from each pass to find the best combination for the car.

Can HKS change the spring rates?

Yes. HKS offers factory spring rate changes for this kit, with the front available up to 20 N/mm softer and the rear up to 20 N/mm firmer than standard. The pillow ball upper mount assemblies cannot be swapped before shipping, so the kit always arrives with them fitted.

Can the dampers be serviced?

Yes. HKS lists overhaul service for the HIPERMAX SP DRAG line, so the dampers can be rebuilt rather than replaced when they need attention after a season of launches. Contact Bulletproof Automotive for current HKS overhaul options and turnaround times in the United States.

Description

HKS HIPERMAX SP DRAG Coilover Kit for BNR32 Nissan Skyline GT-R

The HKS HIPERMAX SP DRAG Coilover Kit for BNR32 is a drag-specification suspension for the RB26DETT powered, all-wheel-drive R32 Skyline GT-R, and HKS is explicit that it is designed for drag racing. HKS developed it from the MAX IV SP using what it learned building the HIPERMAX II DRAG, and tuned the springs and damping to give the rear enough stroke and traction while keeping front traction from the all-wheel-drive system. On the R32 that means an 88 N/mm front spring over a soft 59 N/mm rear. For a street or circuit R32 this is the wrong kit; for a car that spends its weekends at the strip, it is the point.

Features

Single-tube dampers with a large-diameter piston for response and traction
Adjustable shock-body length design, replacing the fixed body length of the earlier drag kit to widen the ride height range and stroke distribution
Rear helper spring with a soft main spring for stroke and traction off the line
PNE coating on the damper body for corrosion resistance
Pillow ball upper mounts front and rear
Special damper oil, with HKS spec change and overhaul service available for the line

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.
