RS*R XBIT981MA Best-i Active Coilover Kit for Lexus - LC500/LC500h

The RS*R Best-i Active Coilover System represents advanced suspension technology specifically engineered for the 2018+ Lexus LC500 and LC500h (chassis codes GWZ100/URZ100). This premium coilover kit is designed to work seamlessly with the factory Adaptive Variable Suspension (AVS) system, a feature that typical aftermarket coilovers cannot accommodate.

Key Features:

• Compatible with factory AVS electronic damping system, retaining OEM adaptive suspension controls
• 24-way damper force adjustment dial located at the base of each shock absorber
• Hand-assembled monotube damper systems with vehicle-specific valving
• Laser-cut aluminum upper mounts combined with rubber bush upper mounts for balanced comfort and response
• Hand-welded lower brackets ensuring precision fitment and durability
• Adjustable ride height with extensive range: Front +50mm to -130mm, Rear +60mm to -65mm
• Recommended spring rates: Front 10.0K, Rear 5.0K (kg/mm)
• Preset lowering approximately 20-25mm front and rear for aggressive stance

The Best-i Active series utilizes RS*R's i☆SHOCK Active technology, allowing the factory actuator to control dampening while providing aftermarket adjustability. This eliminates the common compromise between comfort and performance, delivering responsive handling for spirited driving while maintaining daily comfort. The rubber mount with ball bearings improves steering response on strut-type applications.

Note: Fitment unconfirmed on convertible models. Backed by RS*R's 1-year or 12,000-mile limited warranty covering manufacturing defects.
