M3 Suspension Question

I have a 95 M3 with some 18x9.5 wheels on the back, which forced me to roll the back fenders. Right now I rub a little going into certain driveways and such, but no big problem. However, I need to get new shocks, so I was gonna go with some Bilstein sport shocks, with an Eibach pro-kit (which lowers 0.8"), and I'm worried that this will cause me to rub more often, or all the time. I figured someone who ownes an E36 has had this problem, and this is definitely the site to search for answers on. So if anyone has any insight/suggestions on what I should do they would be greatly appreciated!

I have a friend that had the same problem, and he definately rub the fenders all the time after lowing the car. So he got some 17" rims, and that solved the problem. He figured he could either raise the car back to it's original height, and get rid of the new shocks, and spring he just took time to buy and install, or just get some new smaller rims, and to him getting smaller rims was a better solution.

Turner sells a set of 15mm spring pads for the rear that might raise the car just enough to prevent some of the rubbing:
