If your wanting a good pad / disc combo, you could try the National Sport grooved discs and Ferrodo DS2500 pads. Me and my mate fitted these to my my saff and his 3dr and the brakes are amazing!!

The National Sport discs can be had from Woodford Garage, but I picked mine up from my local factors for £55 for a pair of fronts Think they were supposed to be £55 each but didnt argue about it

Also, Brakes international are good for parts. Picked up all my fitting kits and sliders from here, and the delivery is quick sharp
