Guys, I have just got my S3 calipers back from powder coating and need to reassemble them. The 4 x torx bolts which hold the coloured part of the caliper to the metal body housing the piston are M12 and as best as I can tell the number stamped on the top of the bolt is 10.9, using a guide I have for work that combination suggests a torque setting of 115nm? Does that sound about right?
