OK Guys - just got back to this thread after me holidays!
Max- no need to thank me - thank the guys at Cannon! You are spot on though with your comments re BMW flaps for the
MCS. Looks like you made a better job than me but they really are a doddle to fit.
DSS - looks like max has answered your questions so i'll sit back and relax

sorry for the delayed reply!
As for my rear flaps - getting two new tyres fitted this week and upon inspection noticed a slight rub on the flaps from the tyres so will need to adjust them at the same time as straightening them up.
