I'm about to get some gold SM talons/excels for my '02 426. Beautiful pieces - they come with front and rear Braking waveys - only prob is I'm not sure if the rear disc will fit my rear caliper?? I know the front is the same on 426/450's, (I've got the bracket to make the 320 disc fit), but I heard mention that the 450's use a larger rear disc. Anyone know if this is true?? Riffton.
