Cheers guys. I just had a look at my car and yes it appears that the calipers are the same, they are "SUMITOMO". I am not intending on using the car on the track, just road work so perhaps swapping to the drilled rotors would be a good option, what do you think? I have included a pic of the rotors (front and back), is it stock R32 gtr stuff?? Worth swapping it for my disks?
Cheers again for all the advice
