Updated on

A new tuning program for the BMW Z4 has been released by the guys at SKN Motorsport. They were able to increase the cars power to over 400 hp, while also improving the driving dynamics. However, SKN is not your everyday tuning company, and in their latest press release they mention that the company previously modified police cars for undercover work. This BMW Z4 is nothing like a cop car though, but the list of aftermarket parts will have you checking your wallet to see if you can afford it all. Starting off the Z4 kit is a new stainless steel exhaust system with silencers, mufflers, and tailpipes. For better handling SKN installed an adjustable coilover system, and improvements under the hood come next.

A K&N cold air intake was hooked up, along with an ECU remapping and speed limiter increase. These performance upgrades result in a 0 to 100 km/h time of just over 4.1 seconds, and the impressive 401 horsepower mark. A new braking system was needed for this extra power, so SKN installed 380 mm discs with 4-piston calipers on the BMW Z4. Besides the stock body, the one addition that makes this BMW look custom are the 19-inch BBS Motorsport CH wheels available in either silver or black. The wheels measure up to be 19×8.5 in the front, and 19×9.5 in the rear, which come wrapped in high performance tires.
