Pro Kit 2015-21 Subaru WRX Sedan

The Pro Kit 2015-21 Subaru WRX Sedan from EIBACH is a complete lowering suspension system engineered for drivers who demand both improved handling and a more aggressive stance without sacrificing daily drivability. Built for the turbocharged flat-four platform that defines modern WRX performance, this kit addresses the factory suspension's compliance issues while dropping the center of gravity for sharper cornering response. Whether you're tackling canyon roads or autocross events, the Pro Kit transforms how your WRX behaves under load.

EIBACH's engineering uses progressive-rate spring technology tuned specifically for the 2015-2021 WRX sedan's unequal-length boxer engine weight distribution and MacPherson strut front suspension geometry. The lowering is calibrated to maintain proper suspension travel and avoid bump stops during full compression, preserving ride quality and tire contact patch consistency. Each spring is individually wound and tested to ensure matched rates across all four corners, eliminating the handling imbalances that plague generic lowering solutions. The kit maintains OEM damper compatibility, allowing you to upgrade shocks independently or retain quality factory units.

This suspension upgrade benefits both track-focused builders and street enthusiasts seeking improved body control and visual presence. Installation requires no welding or frame modification—the springs bolt directly into factory mount points using standard tools, though alignment is mandatory after installation. The Pro Kit pairs seamlessly with performance brake upgrades, wheels in the 18-19 inch range, and tuned engine maps, making it an ideal foundation for a comprehensive WRX modification package. Professional installation is recommended to ensure proper spring seating and suspension geometry verification on your specific vehicle.
