About Us

Since 1995, Speedsport Tuning and Spencer Cox have been providing clients throughout the Northeast with honest, dependable and expert Porsche service. While Spencer is a Porschephile at heart, over the years many clients would bring us their non-Porsche vehicles for service. Spencer was the only one they trusted to take care of their cars, so we happily obliged.

As the business continued to grow, eventually SST Auto was born to work exclusively on European automobiles. Spencer added expert, factory-trained Audi, BMW, VW, Mercedes and Mini technicians to provide the same level of service his Porsche customer were accustomed to.

Today, SST Auto and Speedsport Tuning operate out of a modern 20,000 square foot facility in Danbury, Connecticut conveniently located near the Danbury Mall and Danbury Airport.

SST Auto and Speedsport Tuning use the latest factory diagnostic equipment and OEM parts to keep your vehicle running in showroom perfect condition. From routine maintenance and service to major repairs and even performance upgrades, SST Auto and Speedsport Tuning are ready to serve you with expert service you can trust.

About Spencer Cox

Spencer Cox spent his childhood helping his father tinker with his 1965 356C on weekends. His father drove it every day as their only car, and still used the car as his daily driver until his recent passing.

During his summer break when he was 16, Spencer worked for his dad’s Porsche mechanic and found his passion. He moved to California in 1980 to work for a full-service shop very similar to Speedsport Tuning, where they supported clients at the track on weekends, and serviced street cars during the week.

In 1987, Spencer moved back to the Northeast and opened DP Motorsport in Hicksville NY, spending the weekends at Bridgehampton Raceway and Watkins Glen International, two legendary tracks.

Spencer moved back to Connecticut in 1995 and purchased Speedsport Tuning from Larry Prentiss, and in 2010, moved the shop to its current location.
