I am wanting to uprate the brakes on my coupe but one I am not sure which brakes to go for I was gonna just go for the EBCs at the moment Drilled and Grooved Disks and Greenstuff Pads Front and Rear But am also not sure what size my front disks I have I have been told they could be two different sizes depending on what size of Disks Vauxhall put on when the car came out the factory as some came out of the factory with bigger disks depending on what they had sitting... I have heard this before but to do this I will need to measure them is this right and if so do I need to take the disks off and something about the pads as EBC done 2 different shapes for the front some for the earlier version off the coupe 2000-2001 mine is a 2001 on a Y plate so I would imagine they would be the earlier version :?
