So I recently put on a set of Apex EC-7's 18x8.5 front and 18x9.5 rear.
On said wheels I mounted MPS4S's in 235/40 front and 255/35 rear. These were the recommended tire sizes for a 135 with these wheels from Apex (actually they said 265 rear, but 255 would work).

Anyway, I'm getting rubbing in the front when I hit moderate bumps.

My car is still on stock suspension, so I was not expecting this rubbing. Could it be just a worn/sagging suspension that's causing it? My car is a 2012 with 80k miles, and I feel like my suspension may have gotten soft.

Is it likely that it's just a soft suspension that needs replacing?
I'm a little worried because I plan on upgrading my suspension soon and my concern is that any drop might exacerbate the rubbing (or maybe not, if it's firm enough compared to my current aging setup.

Thoughts? Advice?
