Product Description

The RS-R Down Sus Lowering Springs (N135D) are engineered specifically for the 2023-2026 Nissan Z (RZ34), providing a mild front drop and a moderate rear drop that improves stance and handling balance while working in harmony with the Z's factory double-wishbone front and multi-link rear suspension. RS-R designs each vehicle-specific spring set around the OEM suspension geometry, shock dampening rates, and factory ride height of the target chassis, ensuring the springs complement the RZ34's existing performance-oriented setup without accelerating shock absorber wear.

With front spring rates of 10.2 kg/mm and rear rates of 8.13 kg/mm, the N135D is tuned to reduce body roll and improve cornering response on the RZ34 while retaining sufficient compliance for comfortable daily driving. The modest front drop of 15-20mm pairs with a more pronounced rear drop of 25-30mm, giving the Z a visually aggressive stance without compromising ground clearance. As Japan's #1 aftermarket spring manufacturer, RS-R brings authentic JDM engineering and quality to this RZ34-specific application. Backed by a 3-year / 36,000-mile warranty. A wheel alignment is strongly recommended following installation.
