Each pre-assembled system includes application-specific springs, pillow ball upper mounts with adjustable billet camber plates (where applicable), new dust covers and bump stops, and a spanner wrench set. SAE 9254 springs are heat-treated, shot-peened, and powder coated for durability and high fatigue endurance.

The BLOX Racing Plus Series Pro Fully Adjustable 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 Plus Series Pro system allows you to maximize the full potential of your vehicle and further increases high speed stability and performance.

The Plus Series Pro system features a threaded mono-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, application specific front and rear coil springs, full height adjustable perches, pillow ball upper mounts (where applicable) and adjustable billet camber plate mount with high quality radial bearing (where applicable). Each kit also includes new dust covers, bump stops, and spanner wrench set.

The springs used in the Plus Series Pro 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.
