| Does the caliper you bought fit??
Race calipers as far as I can see have 64mm mounts and Brembo standard road fitting is more like 84mm....
I also know that the Race caliper mount on the 916 series is designed to fit the big hub and the 200mm race disk.... road hub is smaller and road disc is 220mm...
So you end up changing the whole backend for a blink caliper. Oh well then you have a very blink backend though!!! |
