As the title I've bought a set of ds2500 pads for the front of my S3 and looking at discs. I replaced my discs with mintex discs and Pagid pads in January this year. After a short time I started with brake judder! I got another pair of discs through warranty and after 4000 miles they judder slightly already. I'm not particularly hard on brakes but these Mintex discs certainly make it look that way. Hubs are true and clean and pads are free as are the slides so time to bite the bullet. As I've said I've bought some ferodo ds2500 pads but not sure what discs to match them too. Do I go oem? I found sound drilled and grooved discs made by kinetix which look good and well priced http://www.ebay.co.uk/itm/271388623196 Also there's these Mtec discs http://www.ebay.co.uk/itm/290642489017 I'm running stage 2+ but usually drive fairly quick A roads and motorway. Also found some Brembo discs at a good price.
