Look at this ring of rust that forms around the center, very difficult to keep clean, anyone have any tips? Maybe should have just got ceramics after all.
Yes, this I have not remotely seen, but ours is mostly garaged. Yes, I suspect this is surface rust on the face of the rotor being scraped off in the next few stops although likely in the rain/still wet based on the picture. And/or rust from the rotors edges and vanes perhaps due to being out in the environment so much. The small band of rust to the inside that you noted above does not seem like it would be the cause of this mess.yea hard to believe but you can take a look here with your own eyes and see for yourself. Not sure how the rust slings off the rotor, maybe when it’s being scraped by the brake pad there’s enough moisture that it creates some kind of slurry that ends up all over the wheel in this sort of pattern. Either way, never really had this problem before. I’ve driven over 88k miles in this R8 and it lives its life outside never really garaged.

too late for that now, I guess I’ll do it on my next set of rotorsHi
Steel will rust and zinc spray on exposed surfaces will prevent rust.
This only works if the disc is new and clean before coating.

LOL that's a 38% exaggeration there salesman regarding Girodisc upgraded rotor weight. The Girodisc 2-piece upgraded aluminum hat slotted rotors are 380 mm x 34 mm and weigh 25 pounds.And they're LIGHT. Serious unsprung and rotating mass removal. Being a premium performance product, they're not inexpensive but are less so than the inferior OEM discs. Girodiscs are lead weights in comparison, especially if you "upgrade to the larger front diameter discs. They're around 40 pound each!
