Hi gents, it is 6 bolt rotors I am after but hanks for the offers. These are great brakes but starting to wish I could have afforded to got brand new. Dyna-ti: 203 up front is only because the adapter kick it out another 20mm and it is a number 3 caliper which is is 183 as standard anyway, the rear number 3 is 160 and bolts straight on. But I am also partial to the odd sausage sarnie!
