1994 The last 964 Speedster

The last 964 Speedster produced was a RHD example finished in slate grey. Known as the Sonderwunsh “Special Wishes” Speedster Leichtbau for its extensive use of light weight materials and its Porsche Exclusive Werk 1 provenance, it is widely regarded as the most collectable version of all.

The current owner is Kevin Yeung, who is based in Hong Kong and has kindly sent me the recent photographs you can see here.


The Sonderwunsch Speedster was specified in the same shade of slate grey as the 1970 911 S used by Steve McQueen in the movie Le Mans – and was the only 964 Speedster painted in this colour. Its 964 RS style seam welded chassis was fitted with a similar suspension to the 964 RS.


It received the hydraulic brake boost system from the RS and Turbo 3.6 (normal Speedsters used the vacuum boost system from the Carrera 2) along with the same brakes as the Turbo 3.6; with four pot Brembo calipers (painted black) and cross drilled and vented 322mm, 32mm wide disks at the front and 299mm, 24mm at the rear.


The car sat on 17 inch 7×17 (front) and 8×17 (rear) aluminum Cup wheels fitted with 205/50 and 255/40 tires. Where a standard Speedster made do with the standard 247bhp 964 engine, the Sonderwunsch Speedster had 260bhp. This was down to a blueprinted engine with remapped ignition and DME chip set with aggressive timing advance characteristics.

To achieve further weight savings it borrowed the alloy doors and bonnet from the 964 RS while replacing the standard steel standard fenders with hand fabricated fenders made from super strong thin gauge steel.

In the end, the Sonderwunsch Speedster took almost 9 months to complete (from start to finish) and was finally delivered to its original owner in London in September 1994 but it was first registered in January 1999 by its second owner in Edinburgh Scotland.
