that's a wide wheel with a fairly tall tire on it... When I went 17x8 with the same tire you have, I ordered with a 4.75" bs, probably going to use either a 0.125-0.25" spacer, but I ordered the wheels with room to grow for a front C5 brake upgrade.
If you look at most cars (like Scot's) with a wide front rim, the tire height is down around 25.0".
Did you upgrade to the S-10 style bump stops that are progressive?
Where is your front fender height at in center of the arch?
What lowering springs?
You can get nice spacers from SC&C that will fit into the control arm pocket. That may be your easiest option to raise the front end, unless you go in and clearance the inner wheel houses. Another thing to check is to make sure your body is centered... if it's not, you may only be rubbing on one side.
