I've heard that the UK Toyota Avensis has bigger brakes that bolt on to a 02 CelicaGTS. It's also said the that the Scion TC shares a lot with the Avensis, but I can't find specifics about the brakes.
If I can simply use "common" TC brakes that would be amazing. Would any one be able to confirm or guide me towards a solution?

Also Just so I'm clear, in ether case, what parts would I need in total to do this? front and rear sets of rotors and calipers... anything else? rear drum pads?
