actually, I disagree mr fly :P
The rears should be fine, you will probably need to run -2 to -3 camber w/ a slightly stretched tire, but 50mm fenders are HUGE.
The fronts will be pushing it, I would suggest running the 40mm dmax front fenders, unless you don't care about rubbing the fender or you won't be that low.
Currently, on my car, I was running x9 +3 & x10.5 +15 (more or less). I have wide front fenders (+20mm) & pulled rear fenders (more or less +15-20mm compared to stock).
The rears, I have only about 1-1.5 negative camber & w/ stretched 265's, it clears everything fine. With your x12 setup, you will be just around 30-40mm more out than my pulled fenders, which will tuck easily w/ another degree of camber. I doubt you'll be running 335's or more (even then may be fine depending on your car).
The fronts however, I rub all over the place, partially from the wide tire, but the rim itself is right on the edge of the fender & I'm already running around 3 to 3.5 negative camber - I'm basically maxed out on the coilover setting (removed camber bolts on the spindle side).
With a stretched tire, I'm thinking 235 or maybe even 255, you will probably be okay, but it is harder to fit the front tire than rear in both our cases.
