We not only service street 911’s, but we specialize in Porsche Motorsport vehicles such as this 991 GT3 cup race car. This belongs to a privateer that recently brought us the car for service as well as track support on weekend track events. New tires and refreshed suspension is all this one needed. Time to hit the track!

Hot rods are usually associated with American muscle cars but Porsches enthusiasts have taken that term and have made its own category of hot rods around the 911 platform. This hot rod is an air cooled powered by 4 CAM motor. Custom colored Fuchs and other bits change the appearance but not to deviate away from its original design. We approve of this hot rod build!

Built by The Keen Project, this Safari built 911 Turbo is number 36 of 36 and is one of our favorites. Due to our extensive knowledge in Air-Cooled Porsches, this car was brought to us to address service and maintenance items. Though we didn’t get a chance to drive the car on trails, we were able to get some seat time around our shop, and this thing is just as fast as some modern day Turbos! What a joy it was to spend some time with this 911 👍
