They are in the UK, and make adjustable ones for front and rear so are good for frp and carbon. They used to sell through East Shore but you can go direct...
Have supplied a few guys on the other channel, Am just sorting some out for mine so my brand new NRG carbon ones will be up for grabs soon.
Oh by the way, the ends on the Teins can be prone to getting a bit of rust on them so a bit of wheel wax is a good idea
