Product Details
The BLOX Racing Plus Series Pro Coilovers are the fully adjustable, street-and-track suspension upgrade for the 2015-2021 Subaru WRX STI (VA). Purpose-tuned 8/8 kg/mm spring rates and 32 levels of monotube damping adjustment let you dial in the VA STI for anything from a low daily stance to an aggressive canyon build. Pillow ball upper mounts and adjustable damping camber plate top mounts (where applicable) deliver direct steering feel and precise corner tuning.
Every kit ships with monotube 32-level dampers, vehicle-specific 8/8 kg/mm springs, pillow ball upper mounts with adjustable damping camber plates (where applicable), dust covers, bump stops, and a spanner wrench set. T6061 billet aluminum construction with nickel-plated shock bodies provides long-term corrosion resistance — important on a VA STI that sees year-round duty. Separate spring-perch and lower-mount height adjustment lets you drop the car without sacrificing shock stroke, keeping ride quality intact at any ride height.
