I personally am using 16" motegi mr-7's... they look alright but yes... they're pretty heavy... almost a year ago it I hit black ice on this one turn and ended up slamming against the curb... with the full weight of the car impacting on just the rim.... I got to leave with just a curbed rim that's scratched up but it didn't bend or crack as some of the lighter rims tend to do... they're built pretty tough in my opinion but just a little on the heavy side and everyone tends to have them cuz they're cheaper than other rims out there... don't get ever get 15" rims of any kind no matter how light they are... you gain acceleration yes... but you lose a centimeter of width per tire and that's actually quite a lot of extra friction you can have on the ground during corners...
