Ford Performance has unveiled a race-modified version of the Mustang at the SEMA motor show in Las Vegas.
The all-new race car has been designed to compete in the FIA GT4 championship, which races on the same weekends as the World Endurance Championship.
The Mustang GT4 was built by Ford Performance in conjunction with Multimatic Motorsports and was inspired by the Ford Shelby Mustang GT350R-C that won the IMSA Continental Tire SportsCar Challenge series last month.
Its beating heart is the same 5.2-litre V8 found in the GT version of the road car. However, it has undergone special tuning to make it fit the series’ regulations – there are strict rules on how much power each car can produce in an attempt to keep the racing fair.
The stock transmission has been replaced by a lightweight, compact Hollinger paddle shift system, which uses direct-pneumatic activation for fast, consistent shifts. Other modifications include a flywheel and twin-plate racing clutch developed by ZF, as well as a dry sump oil system.
Handling has been improved thanks to dynamic suspension spool valve dampers developed by Multimatic, rear lower control arms and stabiliser bars. In addition, the standard alloy wheels have been replaced with lightweight forged items.
Downforce has been massively improved thanks to a front splitter, hood vents and rear diffuser. The rear wing was developed from the one used on the GT endurance racer. Inside, the interior has been completely stripped back to save weight, while a roll cage has been fitted for extra safety.
