KW Suspension V3 Coilovers for 2015-2021 Subaru WRX/STI

KW Variant 3 (V3) Coilovers – 2015–2021 Subaru WRX / STI

The KW V3 Coilovers bring KW’s most sophisticated street-legal suspension technology to the 2015–2021 WRX and STI platform. Featuring fully independent compression and rebound damping adjustability, this kit lets you dial in handling dynamics precisely for aggressive driving, spirited canyon runs, or track day performance. With patented TVR-A (Twin Valve Rebound Adjustable) and TVC-A (Twin Valve Compression Adjustable) technology, compression and rebound can be tuned separately, giving you direct control over body motion, grip, and overall chassis behavior.

Built with INOX-LINE stainless steel construction for corrosion resistance and long life, the Variant 3 system combines height adjustability with sophisticated damper tuning to improve steering response, reduce body roll, and balance comfort with performance.

Spring Rates

• Front: ~7.14 kg/mm (≈ 400 lb/in)
