In the chassis department, there’s a set of 20-inch RTR Aero 5 wheels wrapped in Michelin Pilot Sport 4S tyres (a chunky 305-section up front, and 315-section at the rear), a set of RTR 30-way adjustable “Tactical Performance” coilovers and adjustable anti-roll bars, and two-piece front brake discs. Oh, and RTR makes sure that every car it modifies comes with the Electronic Drift Brake offered by Ford from the factory, to help you get sideways even easier.
It’s the styling that’s probably going to sell the RTR Spec 5 as much as anything though. It features the company’s latest widebody kit – not simply a set of bolt-on extensions, but a full bodywork package that beefs out the front and rear wings and side skirts. The front arch extensions even get extended felt liners while the rear ones feed cooling air to the tyres – probably wise, for a car aimed at spinning them up at every opportunity.
The kit also includes bumper extensions, a carbon chin spoiler, carbon front and rear “wake towers” – those extensions behind each wheel arch to control airflow – and splitters along the sills and aft of the rear wheels. There’s even a new fuel door, since the wider rear arch components would cover the existing one, and the obligatory bonnet vent and rear spoiler, also RTR-designed parts.
Inside there’s an RTR gearshift knob (whether you opt for the six-speed manual or ten-speed auto standard to the Mustang), leather-trimmed Recaro sports seats, RTR-branded floor mats, and a serialised plaque on the dash with JR’s signature engraved into it. You don’t need to stick to Ford’s standard exterior colours either – for $7,500 you can have a “premium” paint finish, or $15,000 for whatever colour you want. The company will rustle up a custom render of your potential car to help buyers decide.
