Best-I 36-Way Adjustable Coilover Kit

The RS-R Best-I Coilover Kit is a performance suspension upgrade specifically engineered for the 2018-2021 Honda Civic Type-R. These systems feature a Monotube design and are hand-assembled to ensure quality and detail. Key components include laser-cut upper mounts, hand-welded lower brackets, and vehicle-specific valving. To enhance daily drivability, urethane bushings are used in place of bearings to reduce vibrations and noise. For MacPherson suspensions, roller bearings are incorporated to prevent spring twisting during steering. The coilovers offer extensive adjustability with up to 36-way adjustable damper dials, allowing fine-tuning of both compression and rebound for various driving conditions. Select models may also offer an optional 1.5-degree camber adjustment by rotating the upper mount plate. Key specifications include a front spring rate of 8.00kg/mm and a rear spring rate of 6.00kg/mm. The kit provides improved handling performance and feel, with the option to lower the vehicle's stance. This kit includes one coilover kit and is backed by RS-R's Limited Manufacturer's Warranty.
