RS-R 2021 Lexus IS350 F Sport RWD Best-i Active Coilovers

If you're looking to significantly improve your 2021 Lexus IS350 F Sport RWD's handling and ride quality, the RS-R Best-i Active Coilovers are a serious consideration. These aren't just about lowering your car; they introduce an advanced electronic damping system that works with your vehicle's factory settings to provide a more controlled and comfortable ride, whether you're cruising on the highway or pushing the limits on a winding road. This system aims to give you the best of both worlds: a lower center of gravity for improved cornering and a sophisticated ride that adapts to changing conditions.

The core of the Best-i Active system is its ability to adjust damping force electronically. It uses a control unit that communicates with your car's original electronic systems, allowing it to make real-time adjustments to the suspension. This means the coilovers can stiffen up for better stability during aggressive driving and soften for a more comfortable experience during daily commutes. The construction features durable materials designed for longevity, and the adjustable spring perches allow you to fine-tune your ride height to achieve the exact stance you want. RS-R is known for its attention to detail, and this system reflects that with its focus on integrating seamlessly with the vehicle's existing technology.

Installation of these coilovers will involve removing your factory suspension components and installing the new adjustable units. Because this system integrates with your car's electronics, it's recommended to have a qualified technician perform the installation to ensure all electronic connections are made correctly and the system functions as intended. Once installed, you'll have the ability to adjust both ride height and damping characteristics, giving you a truly customized suspension setup that balances performance and comfort for your IS350 F Sport.
