The BMW M4 is a perfectly lovely machine. In stock form, its 3.0-liter, six-cylinder, twin-turboed engine makes 425 horsepower and 406 foot-pounds of torque. With a base MSRP of $62,400, that’s a ton of speed wrapped in a beautiful package – far more car than the price tag would suggest.
People far smarter than I will tell you it’s more than enough. But then again, some of us just aren’t that smart. For us, there’s tuner Dinan, here with a package that’s both ridiculous and wonderful because it happens to be covered under BMW warranty.
