In Subaru land, the WRX TR is the build-it-yourself model, though in the adult world, such a thing comes with a 2.5-liter, turbocharged four banger good for 230 horsepower and 235 lb.-ft. of torque. There are also lightweight aluminum suspension bits, a quicker steering ratio, 17-inch alloy wheels, and air conditioning. It’s not quite a stripper, but it’s as basic as the WRX gets.
