Product Description

The RS-R XBIH059MA Best-i Active coilover system is built specifically for the FK8-chassis Honda Civic Type R, giving owners a way to dial in ride height and damping with the same attention to detail RS-R applies across its top-tier coilover lineup. Each unit is a hand-assembled monotube damper, built with laser-cut upper mounts and hand-welded lower brackets, with valving tuned specifically for the Type R's chassis rather than adapted from a generic platform.

Roller bearings address a common MacPherson-strut issue - spring twist as the coilover rotates with the steering wheel - keeping the ride quiet and smooth, while urethane bushings cut down on the vibration and noise that come from everyday driving. Preset ride height comes in at -25mm to -30mm front and -30mm to -35mm rear out of the box, with a wide adjustment range available beyond that (up to -55mm at either end) for owners who want to fine-tune stance and handling further.

As part of RS-R's Best-i Active line, this system is designed to deliver daily-driving comfort without giving up serious performance capability when pushed, making it a fit for Type R owners who want both a refined street ride and confidence on track days.
