SSBC A153 Kit - Wheel Interference

Does anyone have experience with this kit and the use of the factory 14" X 5.5" steel wheels? Mine are hitting the caliper. Called SSBC and sent them pictures where is is rubbing on the caliper and the wheel. They said they they havent had any problems with the mopar kits. They questioned whether they were stock wheels, and suggested the use of a 1/4" spacer. I have seen at least one comment where the rally wheels will work, but not the plain steel. One of the reason I selected this kit is the ability to keep the stock appearance.

Your experience?

Are there any sources for a 4" bolt pattern spacer?

Thanks, Rob
