RS*R XBIT196MA Best-i Active Coilover Kit

The RS*R Best-i Active Coilover System is specifically engineered to work seamlessly with factory Adaptive Variable Suspension (AVS) systems found on select Lexus, Toyota, and Infiniti models. Unlike conventional aftermarket coilovers that eliminate factory electronic damping systems, the Best-i Active series retains full functionality of your vehicle's stock AVS controls, allowing you to maintain comfort, sport, and performance driving modes while enjoying the benefits of adjustable ride height and enhanced handling.

Key Features:

• Plug-and-play integration with factory AVS adaptive suspension system
• Mono-tube construction shock absorbers with premium heat-resistant oil for optimal damping viscosity
• Secondary 24-way manual adjustment dial located at the base of each damper for fine-tuning
• Main damper adjustments controlled through factory AVS system
• Vehicle-specific damping force and stroke rate tuned for both rebound and compression
• Height adjustable via threaded shock body without affecting spring rates
• Steel mounting plates with rubber bushings and roller bearings for reduced noise and friction
• Hand-assembled in Japan with laser-cut upper mounts and hand-welded lower brackets
• Urethane bushings and rubber spring pads to minimize vibration and noise

Adjustment Specifications:

• Preset approximate lowering: Front -25mm to -30mm (-1.0" to -1.2"), Rear -30mm to -35mm (-1.2" to -1.4")
• Maximum adjustment range: Front +20mm to -100mm (+0.8" to -4.0"), Rear -10mm to -50mm (-0.4" to -2.0")
• Recommended adjustment range: Front 0mm to -55mm (0" to -2.2"), Rear -10mm to -50mm (-0.4" to -2.0")
