First-Generation FR-S, BRZ and 86 Front Steering Knuckles and Brake-Package Boundaries

Supported same-badge service chains are SU003-00779 -> SU003-07497 RH, SU003-00780 -> SU003-07498 LH, 28313CA000 -> 28313CA001 RH and 28313CA010 -> 28313CA011 LH. The checked first-generation catalogs use one carrier pair across the standard and factory Brembo brake variants while the caliper, rotor and related brake hardware branch separately; that evidence corrects the queue premise and does not authorize a brake conversion. Broad current service-page applications that also mention 2022-up cars do not establish first-/second-generation loaded-corner or conversion interchange.

Start with the 17-character VIN, US badge, model year, production month and physical side; on these US/LHD cars RH is passenger and LH is driver. Match the cast carrier and its readable service identity before ordering. The Subaru catalog's overlapping December 2016 carrier-number boundary must be resolved by VIN/production data rather than seller year alone; Toyota/Scion's old-to-current service chains do not establish that Subaru production break. In the checked 2017 BRZ and 2019 Toyota 86 catalogs, standard and factory Brembo brake systems branch at calipers, rotors and related hardware, not at the carrier pair. Match the shield to badge/year as well as side: early Subaru and Scion shields differ from the later Subaru and Toyota identities listed above. This is a parts-identification boundary, not a Brembo retrofit recommendation: any conversion still needs an approved complete-system plan for calipers, rotors, pads, hoses, shields, wheels, fasteners, balance and clearance. A bare carrier does not prove inclusion of the separately cataloged hub/bearing, dust shield, ABS sensor, lower ball joint, tie-rod end, brake hardware or fasteners. For a used loaded corner, require donor VIN, readable side/number, straightness and collision history, bearing play/noise, sensor and connector condition, shield/caliper contents and return terms. Use current factory procedures and trained help for steering, wheel-bearing, ABS and brake work, then obtain an alignment and verify brake/ABS operation.

Checked paths include new genuine bare carriers and used bare or loaded carriers. Aftermarket hub/bearing, shield and brake components are separate decisions, not evidence that the carrier listing is complete or correct. Do not buy a listing labeled only FR-S/BRZ/86, spindle, Brembo conversion or 2013-up: require exact side, factory number or supported replacement, VIN/production branch, photos of all mounting points and a written contents list. Reject repaired, bent, cracked, heavily corroded or collision-unknown carriers and loaded assemblies whose hub play, sensor wiring or brake-package contents cannot be verified.

US/LHD first-generation cars only. Match VIN, exact carrier number and side; RH is passenger and LH is driver. For Subaru, resolve the overlapping December 2016 carrier-number branch by VIN/build; Toyota/Scion's service supersessions do not prove that production split. Checked first-generation catalogs use one carrier pair across standard and factory Brembo variants while brake hardware branches separately, but that is not approval for a Brembo conversion. Match the separately cataloged early/later shield by badge, year and side. Hub/bearing, shield, ABS sensor, ball joint, tie-rod, caliper and fasteners are separate unless documented. Current service pages that also list 2022-up cars do not prove first-/second-generation loaded-corner interchange. Reject collision-unknown or bent parts, follow factory procedures, use trained help, align the car and verify brakes/ABS after work.
