I've currently got 18x7 wheels with an offset of +40 rollling on 215/35/18 tires. I also have Tein S-techs — no problems with rubbing (obviously). However, I'm planning on buying some 25mm rear spacers.

Will I rub? With an end offset of +15, I kinda doubt it, but can anyone tell me for sure?

 

I doubt it--99% sure.

Unless you put 3 large adults in the back, then maybe.
