Sports-I Monotube Coilover System

The RS-R Sports-i Coilovers are meticulously hand-assembled Monotube systems engineered to significantly improve the ride quality, performance, and overall comfort of your Lexus RC300/RC350 AWD. Each set is built with a strong focus on quality and detail, incorporating components like laser-cut upper mounts and hand-welded lower brackets. The application of vehicle-specific valving ensures optimal performance tailored to your car's needs. These coilovers feature advanced urethane bushing technology, which effectively reduces everyday driving vibrations and minimizes noise generated by suspension movements. For vehicles equipped with MacPherson suspensions, RS-R incorporates silent roller bearings to prevent the common issue of spring twisting during steering, ensuring a quieter and smoother operation. Rubber padding is also used to further eliminate potential noise from suspension articulation. Adjustability is a key feature, with up to 36 levels of damper adjustment available. This allows drivers to precisely tune the shocks' compression and rebound characteristics to match individual preferences and various driving conditions. The systems also offer refined camber tuning; on select vehicles, the upper mounts allow for an additional 1.5 degrees of camber by rotating the plate. For more precise camber control, adjustable camber plates are available for certain models. Specifically designed for the Lexus RC300/RC350 AWD models from 2015 to 2022, these coilovers offer preset approximate height drops of -35mm to -40mm in the front and -15mm to -20mm in the rear. The maximum adjustment ranges are +5mm to -105mm for the front and +5mm to -60mm for the rear. Recommended adjustments for optimal ride-ability are -10mm to -65mm (front) and +5mm to -60mm (rear). The spring rates are set at 10.0kg/mm for the front and 9.00kg/mm for the rear.
