Blox Racing Street Series II Plus Coilovers for 2015-2021 Subaru WRX STI

The BLOX Racing Street Series II Plus Coilover system for the 2015-2021 Subaru WRX STI now offers ultimate performance and features 32-way damping adjustment for precise suspension tuning and versatility. The large range of adjustment offered by the Street Series II Plus system allows you to maximize the full potential of your vehicle and further increases high speed stability and performance.

The Street Series II Plus system features a threaded twin-tube body for ultimate adjustability to tailor your stiffness at each corner and provides more precise suspension tuning while maintaining suitable ride comfort and quality.

Each pre-assembled BLOX Racing coilover system is constructed for superior durability, specifically weighted front and rear coil springs, adjustable perches, and top mounts. Each kit also includes new dust covers, bump stops, and spanner wrench set.

The springs used in the Street Series II Plus Coilover system are CNC-wound SAE 9254 spring steel to ensure quality and performance. Each spring is then subjected to heat and shot peen treatment, protecting them against deformation and greatly increasing high fatigue endurance. All springs then undergo powder coating for durability and rust resistance. The high-grade materials protect against corrosion and are proven to last not only the lengthiest endurance races, season after season, but also harsh weather conditions.
