Best thing to do is, if you buy a set go on to the RSOC site and look for Andy Penn's guide to fitting them as they have no metal on the inside like the OE parts and can stretch slightly when applying causing you to have over hang and believe me it's the stickiest adhesive i've seen so get it right the first time and they will look amazing.

Price keeps creeping up on these annually so get a set now before they hit £300
