I installed same size tires/wheels on my '09 Brabus coupe. I now run 215/35-17 Hankook tires on 7.5-17 Brabus wheels all around. It really improved the overall grip and road feel of the car.
Running the stock rear wheels and tires all the way around on my 2011 Passion couple. Completely transformed the car's handling, especially on freeways where it used to get tossed around by ruts in the road. It now goes where you point it. No longer looks and handles like a shopping cart with those little front wheels.
Great tip and very easy to do!
