After having my discs sorted they are now vibrating once more when used. If you can imagine ABS then that's the feel. God knows why they have gone so quick but it looks like its T2 for my RR cerb.
I always thougt it odd that there are no cooling ducts leading to the front brakes - there is a space, in the front bumper, to the left of the small lower font lights to run an air duct.
If you still have the bells I would go for the 330mm X 28mm AP disc's, I did this a couple of years ago and they are brilliant. They have put up with lots of abuse and are almost unmarked after about 20,000 miles and probably 12 track days.
