aren't 197's 5 stud's anyways?
Yes, but that does not matter when fitting the caliper, just buy different discs.
They wont fit under a 16 inch wheel, and i m sure it was mentioned on here before that you would need the whole pedal assembely for it to work as well as some brackets.
B*lls. never mind back to the old disc & pad set-up^there for the mk1 clio fella
