Fitment

Please Note: Fits 2018-2021 WRX STI (front) — DBA 5000 Series replacement brake rotor ring, composite (ring only; reuses DBA 5000 Series aluminum hats; high-carbon cast iron). DBA part number DBA53050.1 (from variant SKU dbaDBA53050.1; no part number was in the legacy title). Bucket: 2018-2021 Subaru | WRX STI. FLAGGED: legacy distributor fitment block lists "WRX Base 2018/2021" which conflicts with the legacy description and title ("18-21 WRX STI") — likely a distributor copy error; bucket follows the description text; official DBA verification pending (final sweep). On Sale is genuine: $336.00 vs $537.04 compare-at. Title kept verbatim (naming already compliant). 9 legacy images retained; official-manufacturer status unverified (retailer CDN).
  • 2018-2021 Subaru | WRX STI

Description

The DBA 5000 Series replacement brake rotor ring is the service replacement for the cast-iron ring of DBA's two-piece composite front rotor assemblies, allowing the reusable aerospace-grade T6061-T6 aluminum hats to stay in service while worn rings are replaced. Sharing the performance technology of the 4000 Series, the 5000 Series platform adds weight reduction and improved heat management for high-performance street, track day, club racing and rally use. Supplied as one replacement ring — confirm application, rotor position and compatibility with the existing DBA 5000 Series hat before ordering.

  • DBA part number DBA53050.1
  • 5000 Series two-piece composite replacement RING only (reuses existing DBA 5000 Series hats)
  • High-carbon cast-iron ring for demanding braking conditions
  • Complete assembly uses T6061-T6 aluminum hats with National Aerospace Standards bolts and crimp nuts
  • Reduced unsprung weight and improved heat management vs. one-piece rotors
  • Front brake position; suitable for high-performance street, track days, club racing and rally use
