Centric Parts Premium 120.47021 Vented Front Brake Rotor

It is the 294mm base front rotor for the 5x100 Subaru turbo and FA20 platform. Verified applications are the 2013-2020 Subaru BRZ, Scion FR-S and Toyota 86, and the 2009-2014 Subaru WRX (non-STI). It cross-references to Subaru OE front rotor 26300SA001. Cars with the STI Brembo brakes or the BRZ Performance Package use a different, larger rotor entirely.

Yes. It carries a black E-coating on the hat, edges, and cooling vanes that Centric rates to 400 hours of salt-spray exposure. The friction face itself is machined and double-disc-ground, so the coating there wears off during bed-in, which is normal. Owners generally report clean, rust-free hats, with occasional edge-case exceptions.

Owners on the FT86 and WRX forums broadly report pulsation-free daily service and treat it as a reliable budget replacement blank from StopTech's parent company. Warping reports are rare but not zero, and daily-driver shimmy is often pad-material transfer rather than true rotor warp, so results are not universal. Centric publishes no runout tolerance figure for this part number.

Centric does not publish a specific iron grade or carbon-content figure for this part number. It is marketed as Premium cast iron with symmetric split-core vanes for uniform heat distribution. Because the grade is undisclosed, our metallurgy score is held conservatively.

No. The 120.47021 listing is a single front rotor. A full front pair needs two, and the matching rear rotor is a separate part number (120.47031). Brake pads and hardware are separate purchases.

The Amazon listing for Centric Parts Premium 120.47021 Vented Front Brake Rotor carries a California Prop 65 warning. California requires this warning on a very wide range of manufactured goods — including rubber, vinyl, plastic, and metal automotive parts — whenever trace exposure to any of roughly 900 listed substances (commonly phthalates or heavy metals) is possible, regardless of whether the specific product poses a meaningful health risk. As a passive accessory, Centric Parts Premium 120.47021 Vented Front Brake Rotor has no Safety Data Sheet, so there's no chemistry breakdown to translate beyond that.
