Im really liking the OSIR stuff! Do you order it off their website? Hows the delivery and do they charge any extra for being in the UK?
....Most of my carbon is OSIR. All from TTshop Bedford who are the official European distributers/resellers. Theoretically it's cheaper getting it from across the pond in the good old U S of A... BUT, you'll get hit for UK vat etc etc... Plus, if you have a problem it's much more difficult to get it put right - I once had to reject an OSIR carbon foglight panel because the weave was all over the place, but TTshop were excellent and it was replaced without question.
Some folks have reported fit problems but that has never been my experience. The fit of body panels on the Mk5 Golf ex factory ain't exactly purrfect anyway.
All real carbon is relatively expensive.
I'm posting a feeler later today for carbon fenders (I call them wings) as I can organise a group buy.
