Since 1995, the competition department of Speedsport Tuning has helped hundreds of Porsche clients realize their motorsports ambitions. From their very first track day to a weekend at the legendary Nürburgring and from a high performance driver’s education (hpde) day at Lime Rock Park to a PCA podium at Sebring, we’ve helped our clients achieve their dreams. Some have even gone on to the highest levels of American professional sports car racing. With over 350 podiums and 240 wins in just the last ten years, Speedsport Tuning is winningest Porsche Club of America competition shop in the Northeast!

Our Porsche expertise is unmatched. We’re equally as skilled at adjusting a Weber carburetor in a classic 911, as we are handling the rebuild of the sequential gearbox in the latest 911 GT3 Cup. Speedsport Tuning’s staff of race-tested technicians and Porsche specialists will handle your car with the care that you should demand. We give you that competitive edge from years of knowing and doing what it takes to run at the front of the field. Whether you need logistics and transport for a season of sanctioned racing, or you are getting ready for your first club race or hpde event, we’re here to help!

If you have a Porsche street car, we understand your high standards. Our Porsche street car service department has been providing expert Porsche service for decades. Our factory-trained technicians use factory diagnostic equipment and OEM parts to deliver the service you expect at pricing that may surprise you.

Still going to the dealer for your maintenance needs? If your original factory warranty is up, or your vehicle needs service not covered by your warranty, give Speedsport a try. You’ll be glad you did. We service all Porsche automobiles, from vintage air-cooled classics to the latest versions of the 911, Cayman, Boxster, Panamera, Cayenne and Macan.

Owners of rare and air-cooled Porsches from across the country rely on the unmatched expertise of Speedsport Tuning’s Vintage Department. Equipped with unique tools for special applications, our seasoned technicians cars for cars that would make most enthusiasts drool. On a typical day, you might find a concours-winning Carrera Speedster and an original 718 RSK parked next to a 356 Outlaw wearing a fresh patina of road grime from a multi-day road race.

No matter which Porsche you drive, we treat every vehicle with the same uncompromising attention to detail that you expect. We think of our vintage Porsche department as the perfect blend of hand craftsmanship and modern technology, optimized to keep your classic Porsche running as if it just rolled out of the factory.
