won the championship with the
250 TR 58 placed second with the 718 RSK (pictured) and the 550A RS placed third with the DBR1/300 (pictured) and the DB3S placed fourth with the
Lotus Eleven. After major accidents at the
1955 Les 24 Heures du Mans and
1957 Mille Miglia, the sport's governing body,
F.I.A. and its
Commission Sportive Internationale (CSI) dictated several technical changes to the 1958 Sports Car regulations with engine capacity now limited to three litres. Although Le Mans continued, the Mille Miglia was never run in its original format again and was dropped from the calendar, with the Sicilian
Targa Florio replacing it as the Italian round of the championship. This allowed
Scuderia Ferrari to dominate the season, as
Maserati withdrew from motor racing, leaving
Aston Martin and
Porsche as the main opposition, but as the previous seasons, the majority of the fields were made up of amateur or gentlemen drivers, often up against professional racing drivers with experience in
Formula One. ==Season results==
