The Sport models have 17"x7" rims with a +48 offset. It also has the same 5x100mm bolt pattern as the WRX.
And I am sadly mistaken for the sound deadening on the Imprezas. I had no idea and was just guessing as this is my first economy car. Am I expecting too much from my Impreza? Probably, but now I'm learning more about this car and finding things I still like about it. Thank god this is only a lease.
