The calipers I personally have are part # SUM-BK185MR. Don't use those for the Malibu, though. I have the Hotchkis tubular upper control arms with Caprice tall spindles and 1LE Camaro 12" rotors. My part number is a direct replacement for CAPRICE calipers. Maybe that's why these look so HUGE and beefy. I couldn't ever imagine these things breaking. They're really big (but very light)...The replacement MALIBU part number would be SUM-BK181R....if you want red. They also have clear anodized and black. Hope this helps...about wheel fitment, I think the aluminum ones would fit where a stock caliper would fit. Otherwise, disclamers would have to be all over the place as far as wheel fitment...(like "minimum 17" wheel required")
