They look exotic enough to be Brembo, and may very well be the OE supplier to Cadillac for certain models. Going to have to check those out the next time I'm at my favorite local FLAPS.
Interesting thing about the cheaper brands. When the warehouses switch over to a new supplier, shelf space (and money) is at a premium usually, so instead of continuing to sell the old parts until they're out, they simply get re-boxed into the new manufacturer's boxes.
This might not always be a great thing for us as consumers if they're replacing a cheap brand, but in most cases they're replacing the high-end stuff with the cheap stuff that sells. I was re-boxing a small warehouse near here so the shelves all had Centric boxes on them, and ended up putting stuff like Brembo branded brakes in Centric boxes. Not many, but enough. So the next customer getting that part would have been in for a nice (price) surprise! A $250 part in a $60 box!
Just confirmed on Rock Auto that those are indeed Brembo/Cadillac-V calipers. Same "V" logo and all.
Front and rear have similar units too, with the FE4 performance option and 6-speed manual transmission apparently.
Very cool. But I'm happy enough with mine that even though I feel the need for a set of calipers like yours now, at that price I don't have to run down and buy a set to toss my brand new regular type anymore.
And M_Dogg, just in the last day or two the brakes have gotten even more powerful. Almost aggressive in their stopping power now. Very good feel, and I'm pushing on the pedal even less than before, and they almost feel like drum brakes, where they self-energize and you only have to push the pedal so far and they just keep working. Same here with these larger discs and good pad material.
And speaking of that, I'm guessing the difference is that the pads must be breaking in?
Don't know, but I like it...
