The annual SEMA show in Las Vegas is well underway, and official manufacturer support is greater than ever - not least from Ford.
A huge range of customised Fords have debuted at this year's show, most of which are based on Ford's Mustang and Focus ST and RS performance cars - with a significant number based on the firm's best-selling F-series pickup range.

Joining an official Ford Performance GT4 Mustang race car - with a dry sump, spool valve dampers and an aero package - are cars from MRT, Speedkore Performance, Stitchcraft, VMP Performance and more, each offering a different take on both the V8 and 2.3-litre EcoBoost versions of the latest-generation pony car.
VMP's car, for instance (recognisable from its US Navy-style colour scheme) supercharges the 5-litre V8 to 851bhp and 703lb ft of torque, uses Roush suspension, and sits on Michelin Cup 2 tyres.
Stitchcraft's car is completely different, based on the Mustang Convertible and using a 2.3-litre EcoBoost four-pot and automatic transmission. Changes here are aimed more at style than speed, with airbag suspension, orange paintwork and a retrimmed cabin.
More striking still, but for different reasons, is Speedkore's carbonfibre-clad black car. Like the VMP car it's supercharged, and power output is similar: 825bhp. It sits on Eibach coilover suspension and again wears Cup 2s around its 20-inch wheels.
Perhaps most purposeful is Vaughn Gittin Jr's drift Mustang RTR in familiar Monster Energy livery. Gittin competes in the Formula Drift series and finished third overall in the 2016 season.
The Mustangs are joined by a huge range of customised F-series pickups, as well as a handful of Fiesta and Focus models - among which is a white, wide-arched Fiesta ST developing twice the standard power output. Ford's Fusion (the US market version of the Mondeo) also features, as do a pair of Transit vans.
