Is the Hipermax R GR86/BRZ Cup kit approved for Cup races outside Japan?

No, not automatically. HKS developed the kit as a designated professional series product for the TOYOTA GAZOO Racing GR86/BRZ Cup, and it asks racers outside Japan to check with the series administration in their country. Confirm the current rulebook for your series before ordering.

Can this kit be used on the street?

Yes, but with care. HKS optimized the settings of the Hipermax R GR86/BRZ Cup kit for circuit driving and asks owners to take care on public roads. A GR86 or BRZ used mostly on the street is better suited to the regular Hipermax R or the more street-focused HIPERMAX S.

What changed for the 2025 season?

HKS revised the damping force, the bump rubbers and the front outer fastening structure. The front and rear bump rubbers are now shorter to reduce posture disturbance over curbs, and HKS reports better cornering, braking and acceleration feedback compared with the 2023 model, improving both understeer and traction.

Does the kit fit both the GR86 and the BRZ?

Yes. HKS USA lists fitment for the ZN8 Toyota GR86 and the ZD8 Subaru BRZ from 2022 to 2025, both with the FA24 engine. The two cars share the same platform, and the one-make series the kit was built for runs both models.

What comes in the box?

HKS supplies the Hipermax R GR86/BRZ Cup kit with two front and two rear suspension assemblies, a pair of adjustable front stabilizer links, four spacers, two spanner wrenches and an installation manual. HKS says the stabilizer links should be fitted together with the height-adjustable suspension, so plan to install them at the same time.

Can HKS change the spring rates on this kit?

No. HKS offers overhaul service for this kit but does not offer specification changes. It is supplied with a 78 N/mm front and a 98 N/mm rear spring, both with a 170mm free length, and 30 damping steps at each corner.

Description

HKS Hipermax R GR86/BRZ Cup Coilover Kit for ZN8 Toyota GR86 and ZD8 Subaru BRZ

The HKS Hipermax R GR86/BRZ Cup kit is a designated professional series product that HKS developed for the TOYOTA GAZOO Racing GR86/BRZ Cup, the one-make race series for the FA24 powered ZN8 GR86 and ZD8 BRZ. For the 2025 season HKS revised the damping force, the bump rubbers and the front outer fastening structure, and development driver Nobuteru Taniguchi helped fine-tune the result. It runs inverted single-tube front dampers and normal-type rears, and ships with adjustable front stabilizer links. It is a race kit first, so a street-only owner is better served by the regular Hipermax R.

Development and Testing

HKS shortened the front and rear bump rubbers for 2025 to reduce posture disturbance over curbs, and reports better cornering, braking and acceleration feedback than the 2023 kit, helping both understeer and traction.

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.
