The BMW M4 is pretty high-strung from the factory. It has an incredibly stiff chassis and an overall sense of alertness throughout. For most drivers, it's plenty of car to enjoy on both the street and the circuit, but some owners—like the one of this track-ready M4 coupe—just can't leave well enough alone.
This particular M4 has been modified mechanically and cosmetically to set times at local tracks along the Californian coast. It has your basic bolt-ons—wider wheels, bigger brakes, a cage, racing buckets, and a wing—along with a Stage 2 HP VF engine tune. That brings total horsepower up from 424 horsepower to 525, and total torque to 530 lb.-ft., up from 406 lb.-ft. in the stock tune.
The result of all these mods isn't too surprising. Matt Farah of got the chance to hit some canyon backroads in the track-prepped M4, and finds it especially twitchy through the corners thanks to the overly responsive throttle and excessive power going to the wheels.
That doesn't mean it's a bad car though. It was built for the track, so that's where it should shine. Watch for yourself as Farah takes it for a drive in the latest One Take.
