Fitment

Please Note: Fits 2015-2021 Subaru WRX (rear; excludes EyeSight) — DBA 4000 Series HD plain rear brake rotor, OE-style finish (XG-150 high-carbon iron, Thermal Stability Profiling, Kangaroo Paw ventilation, THGP markings; direct replacement). DBA part number DBA42659-10 (from variant SKU dbaDBA42659-10; no part number was in the legacy title). Bucket: 2018-2021 Subaru | WRX. FLAGGED: distributor fitment table lists only 2018 and 2021 WRX model years while the title and description state 2015-2021 — possible distributor data gap; bucket follows the 2018-2021 range with the 15-21 claim documented here; official DBA verification pending (final sweep). On Sale is genuine: $162.00 vs $258.91 compare-at. Title kept verbatim (naming already compliant). 7 legacy images retained; official-manufacturer status unverified (retailer CDN).
  • 2018-2021 Subaru | WRX
