Brought my new brocks today, they'r 16" and all 4 are 9J, should have checked before but I've got clearance issues at the front. Question is though whats max width I can run on my 280.. I'd guess 8.5 up front and 9/9.5 rears..? Also for anyone who's gone for the 'down and out' look, what set up are you running (width, offset, tyres). Even though the brocks are 9J and I have an 18mm hubcentric spacer, they don't sit out of the arch at all (28 offset).
