Looking to spec my brakes for my middy. Does anyone know of a car with ~285mm solid front discs, with a 4x108 PCD? I'd like to stay relatively light weight on the rotors but I want to use off the shelf parts rather than custom ones. I expect the car to be around the weight of a light locost so I don't expect to need vented discs, but I'd like to run the calculations on it both ways - for that I need to find some part numbers!

Hi-Spec do a 285mm conversion for the Sierra that you can have with solid discs. I think the Sapphire Cosworth used 283mm vented discs as standard.
