Price?????????????????????????/
£200 a pair is the minimum I could make them for to be honest and that's for 10 pairs, I could make them cheaper with a fibreglass core material but the major cost is for the mould anyway so wouldn't save that much, believe me that's cheap.
Any interest?
I have carbon b-pillar trims on mine, from here: http://www.carbon-works-berlin.de/
I have their mirror caps too. Great god quality products, although a few quid, but what decent carbon stuff isn't! Cant rememberthe prices tbh so drop em an email.
