Subaru Japan JDM STI Front Under Spoiler Black WRX | SG517VC010

Subaru/STI part SG517VC010 is the black front under-spoiler for the original VB-generation WRX S4 application. It mounts beneath the front bumper to extend the lower edge and coordinate with the matching STI side and rear aero pieces. Subaru's accessory guidance notes an approximate 40 mm reduction in front clearance and identifies conflicts with certain front-bumper skirt accessories, so steep approaches and parking blocks require extra care. This exact suffix is documented for the earlier VB applied models; Subaru later catalog data uses revised suffixes for newer applied-model updates. The listing is therefore conservatively scoped to confirmed 2022-2024 fitment unless a seller verifies the car's applied model or VIN. Installation requires bumper-edge drilling/fastening according to the correct template and hardware set.
