Need new rotors - advice on correct parts
 

Hello,

It's about time to replace the rotors & pads in my '13 FR-S w/ 65K miles. I don't track my car, but do some spirited street driving.

I decided to go w/ Akebono ProAct pads (ACT1539 & ACT1124). For the rotors, I've browsed many sites (including TireRack, CarID, AutoAnything) and am left confused on the correct size. Some sites show 292 mm discs while others show 277 mm discs (or both).

I'm considering Centric Plain rotors, but can someone confirm the correct part numbers?

Front: 120.47021
Rear: 120.47031 or 120.47029?

Thanks.

In different countries, different brake sizes were offered.

This may shed some light on it, there are a few threads on the subject. I'd purchase the rotors from an aftermarket parts store that knows its market and won't list the wrong sizes. Counterspace Garage, FT86Speedfactory, 86speed, etc. They will offer the correct U.S spec sizes

We generally use the correct size Centric premium rotors on our street cars. They're not listed on our website, but let me know if you want a set.

As far as I know, none of these cars in the US/north america came with the small brakes.

So, yeah, 47031 rear.

The rear pads are also different part numbers between the two, but I think they will still interchange.

USDM Standard Caliper (Vented front and rear)

Front: 120.47021
Rear: 120.47031

I bought these myself some time ago from Rallisport Direct

Some European/Japanese market cars came with a solid rear rotor (unvented).

Thank you, gentlemen! I'm good to go.
