The Porsche 550 has a solid racing history; the first race it entered, the Nurburgring Eifel Race in May 1953, it won. The 550 spyder usually finished in the top three in its class. Each spyder was designed and customized to be raced.

The engine of the 550 is mounted in front of the rear axle making it mid-engined. This gives it a more balanced weight distribution, and allows for largely neutral handling. On the other hand, the low mass moment of inertia about the vehicle's vertical axis can lead to a sudden, difficult to control rotation of the car.

The first 550 had a fully synchronized 4-speed gearbox. Starting in 1956, a 5-speed gearbox was used, but its first gear only had to start and (like the reverse gear) had to be placed over a barrier and not synchronized. Excessive slip to the drive wheels in corners was prevented by a limited slip differential.

The 550 was also raced by privateers, who kept the type in competition after the works team had moved on to the 718 in 1957. The 550 was both a road and track car and it was common for privateers to drive it to the race track, race it, then drive it home.
Each Spyder was assigned a number for the race and had gumballs positioned on doors, front and rear, to be seen from any angle. On some 550s owned by privateers, a crude hand written number scrawled in house paint usually served the purpose. Cars with high numbers assigned such as 351, raced in the 1000 mile Mille Miglia, where the number represented the start time of 3.51am. On most occasions, numbers on each Spyder would change for each race entered, which today helps identify each 550 by chassis number and driver in period black and white photos.
