Lexus IS assistance seats - for all categories (2007-2025)

The helper seats (or side brackets) designed by HIGHROAD / FORMULA PLUS to withstand the high pressure imposed by the sports suspension system in the IS category. Whether your car is equipped with standard helpers or the intelligent variable suspension system (AVS) in F-Sport models, these seats provide optimal support for the helper head, preventing unwanted vibrations and maintaining the vehicle's stability in turns. Key specifications: Universal compatibility: designed for perfect installation on electric helpers (which contain an upper sensor) and standard helpers without any conflict. Heavy Duty rubber: the rubber material used in FORMULA PLUS resists compression caused by heat and strong bumps, maintaining the front height of the vehicle. Steering Bearing: a high-strength bearing ensures immediate response of the steering (DAS) without hearing "clicking" sounds during maneuvering. Model compatibility: Lexus IS: models (2007 - 2025) including IS250, IS300, IS350, IS200t, IS300h. Signs of side bracket damage in Lexus IS: "Click" sound from above: clearly heard when going over a speed bump or dropping into a pothole. Weight or noise when turning: hearing a rubbing or "squeaking" sound when turning the steering wheel while the car is stationary. Steering vibration: a feeling of instability in the front of the car at high speeds due to wear of the seat bushing. Important installation tips: Dealing with the F-Sport system: when removing the AVS seat base, carefully disconnect the sensor plug; our seats provide the proper opening for sensor passage without any pressure. Check the Dust Cover: when replacing the helper seat, always inspect the helper bushing or Dust Cover; if torn, replace immediately to protect the helper and new seat from dust. Proper alignment: pay attention to the arrows on the seat during installation to ensure the correct orientation of the spring (Yai), preventing future rubbing noises.
