Just a bit of imput before you think of changing your disks.
Long time ago I fitted some VTR disks, yeah they looked great and by god stopped the bike but if your using it on a track think twice because on my bike you could feel they gyro effect when flicking the bike over quite a bit.
For track use I used stock SP disks, they are heavier than R more iron me thinks may be wrong. The best thing was I removed the stock bobbins and fitted Brembo full floater bobbins so they were reall floating disks worked a treat.
