Hi Guys a few months ago i felt a judder in the steering wheel under breaking so i though it was warped discs .I bought a set of drilled and grooved on the net , fitted them and everything perfect for bout 6 weeks when the judder came back. I send the discs back to the company as i though they must have been faulty.They replaced them no problem. So i fitted them and perfect again.....for another 5-6 weeks and same again , judder back. Changed pads no differance so i bought a set of standard sti discs second hand which were in pretty good condition , fitted them and again everything seemed perfect until the other day when the judder is back again...any ideas what to do now? cheers...
