Have you guys not had problems with the carriers? Like everybody here has had issues with threads stripping, or just outright breaking.. They appear to be the worst level of junk.. And given what they cost..., jeeze.. Mine stripped out basically within two days. It's happened pretty much to everybody in the German forum I go to.. Have a screw going in opposite direction, held with a nut at the mo.. Luckily a guy at the track who'd had the same problem helped get it fixed..

Talking to another guy now who's made some X-ray ones fit somehow, but I think I'll just order the cheap alu RTR ones for backups..
