Construction & Design

The RS-R Down SUS Lowering Springs are meticulously designed using CAD technology to ensure precise fitment and optimal performance. Made from high-tensile steel, these springs feature a progressive spring rate that offers a comfortable ride during normal driving conditions while providing increased stiffness during aggressive maneuvers. The springs are finished with a corrosion-resistant coating, protecting against rust and environmental damage, which is especially beneficial for vehicles exposed to harsh weather conditions.

The springs' design considers factory suspension geometry, ensuring that the lowered stance does not adversely affect alignment or suspension travel. This thoughtful engineering helps maintain the vehicle's handling characteristics and prolongs the lifespan of other suspension components.

Performance & Handling

By lowering your Lexus IS with RS-R's Superdown springs, you'll notice an immediate improvement in stance and handling. The reduced ride height lowers the center of gravity, which enhances cornering stability and reduces body roll. The springs' carefully calibrated spring rates support a more responsive and engaging driving experience, making your daily commute or spirited drives more enjoyable. While these springs provide a noticeable drop, they are designed to preserve ride comfort, ensuring that your vehicle remains practical for everyday use.

For optimal results, a professional wheel alignment is recommended after installation to ensure proper suspension geometry and tire wear.
