Even though IMSA may not be as well know as other German tuners, such as EDO Competition or Brabus, it can still provide a great power upgrade kit for the Lamborghini Muricelago Roadster. Inspired by the LP640 model the new kit features a minor power bump, an aggressive aero kit and a new wheel and tires package. Named the GTR Spyder, the new car is capable of 708 hp and has a claimed top speed of 217 mph.

The new model is available with a custom wide-body kit which includes a carbon diffuser, a rear spoiler and additional air-intakes. It also features a high-flow sports exhaust system with a valve-control system meant to enhance the noise no matter the speed. No words about the price yet.
