in my honest opinion. with the vmrs in 18x8.5 et35 18x9.5 et33 (assuming so cause you didn't state and thats the most common size in VMRs that would sorta fit) on PSS 235/40/18 fronts and 265/35/18 rears + 5mm up front, you should be very careful of dips/bumps/potholes. I'm also assuming you didn't negative camber out or roll or shave your fenders. The rears should be poking at least 3-5mm and the fronts should be poking more with 5mm. I know this for a fact because I was still poking with pulled fenders on the same offset. You should really rethink adding the 5mm up front cause if you're going on a sharp turn you might buckle in your front fender. The front fenders are pretty much plastic so one hit KO
I'm on a 18x9 up front so no worries about the strut, I'm 1-2mm away from the strut, no problems. And yea, don't lower the car. The more functional way of addressing your problem would be dialing in some negative camber. Good luck. I hope you take my advice cause it would suck to see a messed up 1 series fender.... I know cause that's what happened to me before, but it was hit and run and not because I had the "wrong" offsets.
This being said.... I can't wait for my 245 front and 275 rear setup HEHEHEHE
