Has anyone ever run 17x8.5 +10 on the front? What tire worked for you?

I have The High Offset *(+45MM) Bullitt Wheels on my car for street use.. 17X8 - 245 45 17's Since I have a '69 B Body Rear in there I actually machined the Rear wheels to +52mm for Clearance on the outer Wheel Lip ('67 B Body Axle in the works to solve this)...Here's what that looks like:

Here is some info on my Enkei's...
I ordered 17x8 (+45mm) for the front and 17X7.5 (+48mm) for the rear.

They are super Light and look good too.

You have to install 3" long wheel studs around the car and play with spacers (Sometimes as large as 1.5") and the modern +32MM- +48MM wheels will work fine.

I drove 1,000's of miles this summer on each with minimal front fender trimming / rubbing and -4 Degrees Camber and ~+6 Degrees Caster

How did you eliminate the grease cap issue on the front for the Bullitt Wheels?

Wren I got my car it had a set of 17" 2012 Mustang GT rims and the grease cap cover was an issue on the front as I could not run the factory center-caps for the stang wheels.
