The closer you stay to the oem offset (which is +48mm) the better off you'll be.
18x8 + a drop on +35mm offsets will cause you to rub for sure, no questions asked. I believe 35 is the minnimum offset required for the tC.
Stay as close to stock as possible.
It's not just for "looks" also the longevity of your wheel bearings.
