With these differences in the PSS, along with the increased width, you might run into a rubbing problem on the rear with a 12 mm spacer; however, without the spacer I doubt you'd have a problem. On the front, if you have a rubbing problem with the 15 mm spacer you could switch to either a 10 or 12 mm spacer and solve the rubbing issue.

I plan on running 255/35 and 285/30 PSS in the spring on zcp wheels - zcp wheels are wider and have a slightly more aggressive offset and this will work without rubbing (I'm not using spacers).
I mounted the tires and without the spacers, the rubbing is very slight at full lock in the front. No rubbing in the rear. I've tried a 15mm and 12 mm spacer in the front, but they are too aggressive with this setup. I believe that a 10mm front and 5mm rear spacer will work with the wider tires and the lowered suspension.
