Well there is a known difference in carriers that can prevent 100mm shafts from
clearing when installed in 90mm-native carriers. Somehow there is less
clearance. Wait a sec, I have this in a book somewhere...

Hmm, can't find it in VW Sport Tuning...

I know it was in one of these pesky books...

If someone finds it, lemme know.
