34mm, piccie makes it look much more, do you have the diameter ?, what sierra discs do you have so I know what size these discs are smaller than ?
A few contenders, fiesta 2.0 253mm 34mm height 11mm thick 2004 on,(98-2005 focus/granny/scorp etc etc also), pug 106, 91-2001 1.0 is 247mm 34mm height, 10mm wide, these are the front discs for this car, I'd bet they were this disc, but need diameter!!
