Even more relevant are the new WRX's. They use 245's for 268hp plus in a car that weighs 3400 lbs while the BRZ's come with 215's for 205hp and 2800 lbs. When racing, there is no need to go much wider, only for track tires which are far more sticky. Again, if you are going to FI your car, there is an argument to go 245's on the rear, but given the light weight, even that is a push.
