I tried that to a certain extent, this portion does not get touched by the pad. The inner "hub" part stays black it's just that small ring portion that pisses me off. I know it's nothing to worry about just don't want to see rust when everything else looks clean and nice. I've seen other rotors without rust there and didn't know if something could be done to prevent it.

Paint the rotor hat with high-temp paint, and make sure you spray past all the the rust on the friction disc area. Once dry, drive your car and apply the brakes multiple times. Your pads will literally remove any excess paint, leaving anything untouched by your brake pads painted.

Thanks for the info!

You're not the first one to complaint of the rust ring. There have been a few threads on the subject. Most tape up the rotor and use hi-temp paint. But the paint will peel and flake off with each washing. And you're back where you started from.

Angelo, did you get new wheels?

Long time, Waiz

. No, I've had these CR2Ps for a while now. I sold the 350Z a while back, but still have the TE37s wrapped in RE-11s so I might put them on the 370Z. The only problem is, the offsets (+22) and tire sizes (255/285) are somewhat conservative for the Z34. I have some spacers somewhere, but I don't feel like swapping out tires.

It doesn't matter who's rotors they are. They all rust like that where the pads do not clamp.

old guy · 07-22-2017, 12:48 PM

I would worry more about how dirty my wheels are

Bruggers · 07-22-2017, 09:11 PM

Wheels are dirty from rain and braking the pads in... why wash when it's going to rain again in a day or two, unless you want to clean them while it's storming for me... I'm sure my Z is cleaner than yours on a regular basis.

The only way to prevent rust is to exclude Oxygen from the Iron. The best way I know to do that is with high-temp paint (as mentioned above).

Make sure to get rid of over-spray on the pad contact area (sanding works well) as the paint can clog the pads. Not usually a problem but why take a chance?

The downside with hightemp paint is that it will trap more heat into the rotor. This technique is not recommended for extreme usage unless you have really good cooling. Surface rust is not a huge problem outside the aesthetic downside. If you do paint them, tape up the inner vanes.

Excellent point. Paint only visible surfaces that are causing a "problem" (no need to paint anything on the back side).

I used to have this problem when I had my 09' Z and it was annoying. Plus it makes the car look older. But I've had my 15' Nismo for almost 3 years and 30k miles and haven't run into that issue again. I'm thinking Nissan painted that inner ring. Whatever they did it seems to be working.

I'd just move to a very arid climate and never let that ring get wet
