I are getting ready to order wheels/tires. I am getting the magnum 500 style wheels. they are either 18x9 in 36mm offset or 18x10 in 45mm offset. I have vogtland/koni, control arms, etc alreay on the car. I currently have the stock sway bars. I need help with which wheel and what tire size. looking for the best combination of ride, handling, traction. need help.

18x10 in the 45mm offset with either 275/40/18 or 285/40/18 (I prefer this size) will fit fine at the corners. With the turbo, you need all the rubber you can get, so go wider.
