I used a spacer on the rear wheels. The outside edge of the wheels and tires are located and look the same (as the OE wheels and tires) in terms of their location to outboard side the wheel housing. Sourced a 10mm spacer for the rear wheels. The rear tires are also 1" larger (than OE) in diameter. The front and rear suspension was lowered 1/2". The speedometer was corrected +4%.
