Hi - new to the group but really enjoy the site! Good information! I've spent hours looking through threads but haven't found what I'm looking for. If it's already been posted, my apologies. Still learning the site. I have a 2011 Legacy 2.5 Premium with 16" wheels. A friend has sold his 2014 WRX STI and has offered his aftermarket wheels to me - Enkei T6S 18"X8.5. Will these wheels fit on my car without body modifications? If so what size tire should I run, and anyone have tire recommendations? Daily driver with 60 mile commute in sun, rain, snow. Thanks for the help!!
