Fitted the 400mm front and 380mm rear brakes from the M2cs.

The braking performance is just astonishing compared to the standard m2 blue brakes but comes with a trade of adding unsprung weight.

I'm waiting for my race brake builder to finish his CCB's for these callipers as the factory ones do crack or damage easily and unless I get the stock ones really cheap, I'll be waiting on him to come up with something at a fraction of the cost.

Here is a comprehensive list of the stock brakes and their weights, I also added CCB's and my race brake setup from Albert racing which served me really well for a number of years and are still in perfect condition.

As you can see why the CCB's are so attractive but come at huge cost.
