Yeah, the previous owner's rangimod brake ducts. According to him they couldn't be mounted in the fog light holes because the radiator support panel gets in the way. Yes they looked ugly but helped immensely - he used to crack front brake rotors at Manfeild all the time before installing them
He gave me his spare BFMP/BFMR front rotors, brand new in their Mazda boxes, but I never used them, and eventually upgraded to Galant slotted discs and 22V Mazda calipers instead.
Haven't even had a chance to give them a good run, my car's been sitting in the driveway with frontal damage for the last couple of months
