The brakes are much better than the std set up especially at high speeds,which is a bonus when you have 1 of the best motorways in the country 6 minutes away(M69).
I have found there is no need to get brakes warm as cold braking is good and effective.
Brake dust is basically non existant,and despite the claims about needing to bed them in,there were no issues.
Overall a worthwhile investment and one I feel compliments the car with the extra power.
