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.
