Who doesnt want to be a race car driver at the weekend?

This is a rare opportunity to own and experience an incredibly well built 2001 Porsche 911 C4 track car.  The car was built as a personal track car by the owner of a well-known shop in the suburbs of Chicago.  Specializing in Porsche, the owner built the car to highlight and promote the shops skills.  The car was designed for fun and never used for serious competition.

The goal of the project was to build a high-performance weekend track car that would demonstrate the ease of the conversion from older street car to fun track car with a water-cooled Porsche.  A crucial part of that goal was to maintain a reliable vehicle that was easy to service and simple to evaluate diagnostically.  All electronic and mechanical systems in the car function the same way they do on a street car.  The exception is hvac you dont need that at the track!

The car features a hand built and heavily modified M96 2003 S 3.6L engine that was enlarged to 4.0L - dyno tuned to output approximately 425 HP and built to extremely precise tolerance levels.  From engine through brakes and suspension, every upgrade possible was addressed to produce a fast, fun, safe and reliable car.  Lots more detail below.

To try to describe how incredible the car drives just wont do it justice, but I will try.  Before you even get rolling, the sound it makes is utterly incredible.  If you like a deep throaty normally aspirated sound that has nothing to hold it back with no mufflers, custom headers with a crack and spit that you would only see at a race track coming out of its titanium tips, then this car will make you smile as you settle into your Sparco race seat and buckle into your 5-point harness.  As you tip the throttle and lift off the clutch the immediate response from the acceleration is incredible.  Its performance is rocket fast and its suspension is set up so well that its turn in happens so quick and it travels around the turns as if it was glued down without the hint of roll.  Until you actually tap the brakes, you dont realize how quick you had built up speed and then you realize how quick the enormous 6 piston Brembo brakes in the front and 4 piston Brembo brakes in the rear bring you to a grinding halt.  Truly invigorating in every way.

I am listing the majority of its modifications below along with several videos and enough pictures that should truly give you the sense of what this incredible car is all about.
