Subaru OEM STI Rear Quarter Under Spoilers Black WRX | E5610VC010

Subaru accessory E5610VC010 is the pair of black STI rear-quarter under-spoilers mounted at the outer lower corners of the VB WRX rear bumper. STI cross-references the same component as SG517VC210 in the Japanese accessory catalog. These are side spats, not the full-width rear under-spoiler/diffuser represented by E5610VC110, so the corrected title distinguishes the two assemblies. Current Subaru accessory material covers 2022-2026 WRX applications. Subaru identifies an incompatibility with the factory splash-guard set because both products use or overlap the same rear bumper area; aftermarket mud flaps should likewise be checked for bracket interference. Installation requires accurate positioning and bumper-edge fastening with the correct hardware/template. Test-fit both sides and compare symmetry before drilling or applying any adhesive pieces.
