The 280mm version fits the ITR/NSX/Legend/Spoon Caliper setup. Pair these with ‘07 Mini Cooper (280mm Rotors non S ) and ITR/NSX/Legend/Spoon Calipers and you’ll have that budget Big Brake Kit (BBK) you’ve always needed. \
The 294mm version fits the Honed Development kit. Pair these with the HD Porsche kit ( ‘06 Mini Cooper S 294mm Rotors) for a bump in performance over the 280mm kit.
