I was looking to run 17x8 *28 , on 235/45/17 with tein lowering springs , anyone run a similar setup ? Will I need spacers , or will I rub at all ? What do you guys think

 

With lowering and that tire width, the front will almost definitely hit the fender unless it is rolled/pulled. There will be a lot of inside clearance. The rears should be just fine.

I have 17x8 +30 with 215/45/17s up front, and the tire edge is almost perfectly parallel to the outside of the fender. But it's also at stock ride-height.
