Why take a risk on something as important as brakes esp on a car that needs all the help it can get to stop. Even though the OE disks are Brembo manufactured they may be higher spec than the regular ones as I noticed ground areas on the inner edges on my OE Brembo's where they had been balanced as there is a lot of rotating mass which could well induce vibrations. 2012 TDV8 Vogue (L322)

To be honest i only changed mine as the grey painted hubs where scruffy and looked bad but the new Brembo are painted in a dark grey which looks really smart so i,m very pleased with them . seem to stop well also  overfinch modified
