cheers for the input mate.

My apologies I've probably taken this thread off topic. I wanted to just show off this awesome brake upgrade for people with the same hub as mine.

As far as your statement though I'm going to have to disagree. If width and offset were the issue then TE37 and CE28s (15x7 +35) would also not fit. As a general rule, and if all else was equal then width and offset would be the issue.
I appreciate your input but it's actually the wheel and spoke design which is the issue.
