I have to say that the brakes were the only question mark when I bought my Cupra, originally the factory were going to fit brembo's but (IHMO) were told by the beancounters to fit R32/S3 brakes for cost and supply reasons,
From what was said on here, it was because the brembo's couldn't perform as well as the R32 ones, so the brembos were ditched for the better brakes.
And, from what everyone else has said, they do perform better than the old Mk1 brembo's so i wouldn't be too upset.
