THe S3/ R32 brakes are a great upgrade over the stock 312mm brakes. Fact.
Yeah sure they are a fair bit heavier but they are more powerful, have better feel, are more progressive and of course - they look better
As everyone running these says, the benefits of having them far outweigh the extra weight (which you don't really notice tbh)
Unless your running fancy wheels like Jay
, these are a great OEM+ upgrade that won't break the bank
