Fitted the Brembo GT front brake package earlier in the year and they are awesome. But now, the standard rear S3 discs look a bit small and weedy so I would like to get new larger one's for the rear which match the front and are drilled. I will also need some adaptors to 'space' the calipers out so l can retain the original calipers and therefore just buy the discs and adaptors. What are my choices and has anyone done this already? I assume my best bet is to simply buy a pair of rear discs from Brembo? Lastly what size would you recommend so they look bigger but don't upset the braking balance?
