But CarBahn isn’t building its cars for average consumers, and for people like Steve Dinan, good is the enemy of great, and great can become divine if pushed just a little harder, with bigger turbos.
In stock form, the C63 S makes 503 horsepower, and while that’s plenty, CarBahn couldn’t just leave well enough alone. The 4. 0-liter V8’s stock turbos were swapped out for bigger ones, which not only increases power, but changes the engine’s torque peak.
Steve decided that there was more to life than fiddling with Bimmers, so CarBahn works on all kinds of things, even going as far as campaigning an Audi R8 in the Blancpain GT World Challenge series.
Steve Dinan recently started a new company called CarBahn Autoworks, and he’s on a mission to find ways to make the already-lovely C63 S even better.
The bespoke Forgeline wheels from CarBahn add half an inch in width and a full inch in diameter, both front and back.
CarBahn’s first modification replaces the standard C63’s rolling stock with better wheels and tires.
If Steve’s last name sounds familiar, it’s because his old company Dinan Engineering was one of the most dominant forces in the BMW performance aftermarket and American road racing.
Cars like this are hard to enjoy even on a canyon road, simply because they’re so fast, and while I’m sure the CarBahn C63 S would be extremely competent on a racetrack, I don’t know if it would be my first choice for that either.
Steve decided to keep the factory dampers, but had a set of progressive springs made that would lower the car slightly and take some of the motion out of the vehicle as it cornered, without making it overly stiff.
The CarBahn GT-S kit seen on this car costs an additional $21,890, plus an extra $9,800 for the nifty wheel and tire package.
