Whiteline Grip Series Stage 1 Suspension Kit for 2015-2021 Subaru WRX & WRX STI - GS1-SUB008

Fits 2015-2021 Subaru WRX and 2015-2017 WRX STI. The Whiteline Grip Series Stage 1 Kit is an engineered handling solution designed to reduce body roll, improve turn-in response, and provide a more aggressive stance without compromising daily ride quality. This comprehensive kit replaces soft factory components with performance-tuned alternatives, featuring progressive rate lowering springs and multi-point adjustable sway bars.

• Lowering Springs: Delivers a consistent 20mm drop front and rear with spring rates of 6.1kg/mm (329lb/in) front and 5.8kg/mm (325lb/in) rear.
• Adjustable Sway Bars: Includes a 26mm 2-point adjustable front bar and a 22mm 3-point adjustable rear bar for precise chassis tuning.
• Heavy-Duty End Links: Eliminates flex and allows for up to 25mm of on-car length adjustment to remove sway bar preload.
• Advanced Bushings: Synthetic elastomer mounts with internal bore knurling and grease reservoirs for quiet, maintenance-free operation.
• Durability: Metal components feature protective plating and powder coating to resist corrosion in harsh environments.

Each GS1-SUB008 kit includes DIY lateral locks to prevent sway bar shifting under cornering loads, extreme pressure molybdenum disulphide grease, and a detailed installation guide. These components are designed to work seamlessly with factory dampers while maintaining correct alignment geometry.
