Looking Style 68’s for sale, 17 or 18 and any width, decent condition is good enough for me, if any of y’all got some let me know your number! Thanks

Going through with a “zhp conversion” on my 325xi and am about to purchase some style 68’s, offsets are 7.5 for fronts and 8.5 for rear, I’m aware that I cannot run different sizes tires, or shouldn’t at least, but if I run a square set up, will the offsets not being the same cause any damages?

I've wanted to space out my wheels for a while now, and I think I'm about ready to do it. My question is, for an aggressive look all around, should I get 4 spacers or get 2 more rear wheels for the front and just run rear spacers? The car is my daily driver, and I do some "spirited" driving, but...
