How did you guys go with clearance between the callipers and wheel spokes?
I've had an email exchange with the guy who offers a 4 piston Brembo kit to suit 17" wheels (see thread below) but he says I need a minimum of +35mm offset on my wheels.

I have 4-7/8" backspace on my 17x8s which converts to roughly +10mm positive offset. Too much dish!
