Hi, I've got a exiga 2010 sti version. I need to replace pads and discs but was wondering if any other models share the same parts so I could then search for performance discs and pads. Finding it very difficult to confidently search for parts especially any performance parts. However I'm sure there's some models that have exact setups the same as the exiga just need to find someone knowledgeable enough to advise me :(
