I think i've posted this before, but when I ordered my Amuse bumper, once it got here the body shop basically cut the fiberglass tabs off bumper and glassed in a small piece of metal going up at an angle. The tab on the fender was also bent up to match that angle.
It got me a lot more clearance, but its just a crappy design overall, our tabs are almost on top of the tire, makes it really tough to tuck any kind of tire and still have wheels sitting flush without running extreme strech on the tire.
