the Z4M bushings push the front hubs forward, not out. it would not have an affect on wheel offset.
oh ya... definitely. it's cavernous. have you unlocked the hidden storage under the rear seat? easter egg...
thanks for the pic. i love the "let's just see what the Touring can do today..." pics. :) i take a whole bunch that i never post, LOL.
looks like you've been rubbing on the very top inside lip of the fender too.... might want to roll that sucker a tiny bit. i'm doing mine this spring.
oh, and you're missing a fastener there? liner-to-bumper. should be a coarse-thread M8 with a big washer.
