RS-R XLIT997MA Best-i Active Coilovers for 2016-2020 Lexus GS-F

Vehicle Fitment

• 2016-2020 Lexus GS-F, Chassis Code: URL10

Fitment Notes

• Compatible with the factory AVS (Adaptive Variable Suspension) / DDS system - the factory electronic actuator continues to control damping on this coilover, unlike standard aftermarket coilovers that lose this function
• Not the same part as RS-R's standard (non-Active) XLIT997M Sports-i coilover, which does not retain AVS compatibility and carries a different spring rate - confirm you're ordering the "MA" Active version if AVS retention is required
• Not an emissions-related item

Features

• Retains full function of the factory AVS/DDS electronic damping controller - damper adjustments continue to run through the factory system rather than losing electronic control
• Monotube, hand-assembled damper system engineered to boost daily driving comfort and performance while remaining track-capable
• Laser-cut upper mounts and hand-welded lower brackets, vehicle-specific valving, all hand-assembled for precision and quality
• 36-way damper adjustment, front and rear, compatible with factory AVS
• Roller bearings eliminate spring twist noise on MacPherson-type suspension as the coil springs rotate with the steering wheel

Product Description

The RS-R XLIT997MA Best-i Active coilover system solves the problem most aftermarket coilover swaps run into on a factory-AVS-equipped GS-F: the electronic adaptive damping system normally stops working the moment the factory shocks come out. RS-R's Active Series is built specifically to retain that factory control, so 2016-2020 GS-F owners can lower and upgrade their suspension without losing the electronically adjustable damping built into the car.

Beyond the AVS-retention feature, the coilover carries RS-R's full build standard - hand-assembled monotube dampers with laser-cut upper mounts and hand-welded lower brackets, plus roller bearings to eliminate spring twist noise as the suspension rotates with the steering wheel. Dampers offer 36-way adjustment front and rear, letting owners fine-tune compression and rebound on top of the factory AVS control rather than instead of it.

A front spring rate of 10.00 kg/mm pairs with a notably firmer 14.00 kg/mm rear rate, tuned specifically for the GS-F's V8 power and chassis balance. Height adjusts well beyond the factory preset - up to -75mm at the front and -40mm at the rear - giving GS-F owners real range to dial in stance while keeping the factory AVS damping system fully functional.
