HKS HKSTUDIE SUS Coilover with Canceller for G8X BMW M2 / M3 / M4

The HKS HKSTUDIE SUS with Canceller is engineered specifically for G8X M models to balance high-speed stability with genuine city-driving comfort. Developed around the concept of “balancing high speed stability and comfort for city driving,” it uses high-rigidity mono-tube dampers with inverted fronts to handle the heavy bending loads of acceleration, braking, and cornering, delivering precise and confidence-inspiring handling. Fully-threaded shock bodies front and rear allow ride height adjustment without compromising comfort, while a 30-level damping force adjustment lets the driver fine-tune the setup for everything from daily commuting to track use. The front features camber-adjustable spherical-bearing top hats for sharper turn-in, with CNC-machined aluminum top hats at the rear for strength and precision. Paired with an integrated canceller to work seamlessly with the factory electronic damper system, this coilover kit transforms the G8X into a more composed, responsive, and refined “Ultimate Driving Machine.”

Balancing High Speed Stability and Comfort

The G8X-generation M models are equipped with electronically adjustable dampers from the factory, which deliver the high-speed stability characteristic of the M series but can still feel firm in everyday use, even in COMFORT mode. HKSTUDIE SUSPENSION was developed around the concept of balancing this high-speed stability with improved comfort for city driving.

High Rigidity Inverted Dampers

The system uses mono-tube dampers, allowing for a large-diameter piston and providing consistent, high-quality damping characteristics. To cope with the significant bending loads that occur under acceleration, braking, and cornering in the strut-type front suspension, high-rigidity inverted dampers are employed, resulting in noticeably more precise and confident handling.

Fully-threaded Shock Body

A fully-threaded shock body is used front and rear, enabling ride height adjustment without negatively affecting comfort by altering damper stroke or spring preload. Because the factory ride height leaves a relatively large gap between the front tire and fender, HKSTUDIE sets the front slightly lower than the rear to achieve a more aggressive stance and enhanced high-speed stability.

30-level Damping Force Adjustment

With 30 levels of damping adjustment, the driver can fine-tune the suspension for everything from daily commuting to circuit driving. This range of adjustment helps deliver a more evolved interpretation of “The Ultimate Driving Machine,” combining a smooth, composed ride on the street with a stable, planted feel at higher speeds — ideal for M models.

Camber-adjustable Top Hat

The front assembly features camber-adjustable spherical-bearing top hats to sharpen turn-in and improve front-end response. At the rear, CNC-machined aluminum top hats are used for a precise fit, light weight, and long-term durability.

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.
