Specific Question About Sport Rotors

RonZwanson · 07-17-2013, 08:56 PM

So tomorrow I'm going to change the pads on my sport package. (Just standard street pads...) I'm not planning on changing my rotors because I don't believe they're in need of replacement. I just had the wheels off the other day, and there's no scoring/rough edges, and there's no evidence of warping. I don't drive the car very hard and don't abuse the brakes.

My question is if anyone has ANY idea what the minimum thickness is for the stock sport rotors. I'd like to be thrifty and not chuck good rotors, but I also don't want to be unsafe and drive on rotors that are too thin. I'm the second owner of the car, and I've put about 16k miles on it, (for a total of about 62k) so I don't know how many miles are on the rotors total. When I bought the car the dealership rated their life at 9/10, but regardless I'd like to check them out with a micrometer to be sure. That said, there's no point if I don't know what the limitations are.

If anyone knows I'd appreciate the help! Thanks!

I think your over thinking this hole thing. I'd say you have a way way way better chance of warping your rotor before it wears to thin..imo

unless you turned them or resurfaced them, it ain't happening

I know it isn't an answer, I just don't have one, and I KNOW you'll be within stock specs

Nailed it. Over thinking stuff is kinda my thing. Ask my wife.

The rotors have never been turned/resurfaced, so I also think they'll be fine. Based on your responses, I'll drive along completely oblivious to it, and if I'm in a fatal car accident I'll let you guys know.

I'll probably measure them to see where they're at, just to scratch the itch. Thanks for the responses.

Attached is a PDF of the brake specifications from the 2011 370Z Service Manual
