A few traders on here who can do decent deals on pads. BigPhil sells at a good rate from experience, PM him.
Also for tyres, check out
http://www.camskill.co.uk/ - very cheap
http://www.event-tyres.co.uk/ - good service and fit them on your drive for you
And you might want to consider getting Toyo's or Falkens instead of Bridestones. I've got Falkens and they have much better grip than the Bridgestones
