Östgöta Sportvagnsklubb

Members own both newly manufactured sports cars and older ones from the late 1920s.

ÖSK has just over 400 members and over 600 cars in its register. The club's purpose is to promote interest in sports cars and to bring together people interested in sports cars.

ÖSK organizes several events per year, normally about 30 different meetings/drives a year. Track training at Sviestad race track is held ten times a year together with Linköpings Motorsällskap. The club is also affiliated with the Svenska Bilsport Förbundet (SBF), and some members compete successfully in the club's colors.

The club magazine ÖSK-Nytt is published four times a year and contains reports on club activities and tests of various sports cars. A one-year trial membership is offered.
