HKS HKSTUDIE-SS001C Coilover Kit HKSTUDIE for BMW M3 (G80) / M4 (G82)

High performance coilover kit that balances high speed stability and comfort for city driving

• The G8X generation M has electrically adjustable dampers as stock, and while they provide the stability typical characteristics of the M series at high speeds, they still are a bit stiff in daily driving, even in “COMFORT” mode. The HKSTUDIE SUSPENSION was developed based on the concept of “Balancing high speed stability and comfort for city driving”.
• The mono-tube dampers are equipped, which enables the use of a large- diameter piston and provides high-quality and stable damping force. In addition, high rigidity inverted dampers are used for the front suspension, as the strut type suspension system is subject to heavy bending loads during acceleration, deceleration and cornering. This leads to excellent handling.
• Fully-threaded shock body is adopted for both front and rear, allowing adjustment to the desired ride height without affecting ride comfort by changing the amount of damper retraction stroke or spring pre-load. Wheel gap between the front tire and fender is noticeably big with the stock ride height, so we set the front end slightly lower relative to the rear to obtain a more stylish appearance and improve high-speed driving stability.
• The 30-level damping force adjustment allows the driver to set the preferred damping force to suit various driving conditions, from city driving to the race track. You will experience the evolved “The Ultimate Driving Machine” by having balanced performance of smooth ride on the street and a steady driving feel at high speed, perfect for the M series.
• The front unit features the camber-adjustable spherical-bearing top hats for sharp handling. CNC machined aluminum top hats are adopted for the rear unit.
• “Suspension Error Canceller" is included in the kit to delete the error light upon removal of the electrically adjustable damper.
• By manufacturing in-house at our factory in Japan and conducting thorough quality control, we are able to offer a 3-year/60,000 km product warranty coverage from the time of purchase. We also offer overhaul and customization services after use. In addition, we can change the spring rate of the front springs for free at the time of product order.
