Any sign of sinkage into the holes..i have found this on one set of plates on my brother in laws bike..No idea who did them. Had mine done in a random woven material by an old timer near Norwich and they are fine.You have a job to beat Saftec turn around knowledge and expertise they can certainly turn a clutch plate covered in holes for cork insertions into a full face dual sided non slip item in 3 days door to door
