Speedline Wheels

Speedline is an Italian wheel maker based near Venice, with a long history of racing wheels for Formula 1 and rallying. Its racing and aftermarket wheels carry the Speedline Corse name. For Porsche it made the 18-inch multi-piece 'Speedline for Porsche' wheels of the 964 Turbo S, Turbo 3.6 and Carrera RS 3.8, and the 18-inch three-piece wheels of the 993 Carrera RS. It also made cast Cup 1 wheels for Porsche and magnesium-center wheels for the 993 Supercup race cars. For Ferrari it made the F40's 17-inch three-piece center-lock wheels and wheels for the 348 and 512 TR. Speedline also built wheels for RUF and TechArt and sold designs under its own name.

Spotting a replica

Genuine Speedline wheels have Speedline casting marks, an SL model number, 'Italy' or 'Made in Italy' and date codes on the back. Wheels made for a carmaker also carry its part number, such as Porsche's 965.362 and 993.362 numbers. The 18-inch 964 and 993 RS wheels have 'Speedline for Porsche' etched on the lip, but a refinisher can reproduce that etching, so check the cast marks. Porsche kept supplying the 964 Turbo wheel as a new part, so genuine wheels can carry date codes from the 1990s to the 2020s. Three-piece 'Speedline-style' copies exist, such as RH wheels made in Germany. The 964's 18-inch Speedline wheels should not be taken apart, because they can't be reassembled with standard shop equipment.
