RENNtech hast turned the already factory tuned C63 AMG into a beast; with 580hp (130 more than the normal C63) and a top speed of 187 mph, you’re almost guaranteed a ticket on your first spin around the block. The RENNtech engineers have actually thought about that, and how annoying cops can be when you’re trying to go 75mph in a 35mph zone, which is why the have partnered up with Technicar. Together they designed and implemented a secret weapon that will warm you if any police radar guns or even laser guns are being pointed at you car. Not only does it warn you and show you the direction from where the radar gun is being fired from, but it also has built a in systems that confuse the radar and laser gun, which makes them spit out wrong data to the police officer. RENNtech packaged the warming system into the rear-view mirrior of the C63, making it seem like it was there when you bought it.
