Cooper s jcw ... brakes are ****

Hi everyone. I am looking at gaining a few more horsepower from the 192 firebreather.

but the brakes feel terrible!! and i really want some nice looking grooved disks..

can somebody please put me in the right direction of getting the right set of brakes and pads that will give me much better braking..

and also im feelign a bit cheeky i must say, can someone tell me where i would get 250 bhp from?

Chris :D
