im running 9's on the rears and 8's on the front but the 9's have a pretty high offest +67 with an 8mm spacer might up it to an 15mm one soon tho =P no mods to guards for me tho

to widen the guards, you could roll the lip so that flap on the inside is flat allowing a little bit more clearance
or you could flare the guards giving more clearance too
