This lot will be auctioned via Iconic Auctioneers, The Iconic Sale at Supercar Fest 2025 on Saturday the 17th of May, Sywell Aerodrome, Sywell, Northampton, NN6 0BN. Long established St Johns Wood specialist dealer, Clive Sutton, has been at the forefront of the luxury and performance car industry for many years and one of the largest importers of Ford Mustangs and Shelby Mustangs for over 15 years. More recently, when the S550 Mustang became available in right-hand drive in 2015, they started to build a performance and custom upgrade program, The Sutton Mustangs, with the focus on dynamics and handling, more relevant to UK roads. The Sutton CS800 Mustang was revealed in 2017 at the Top Marques show in Monaco. Based on the 5-litre V8 model, the CS800 boasts a high performance supercharger system that increases the engine's power output to 800bhp, delivered through a 6-speed manual transmission with the Ford Performance short-shift gear selector. The CS800 Power Package uses a stage 2 Whipple supercharger, upgraded intercooler, new injectors and a larger throttle body. A new exhaust system with long tube headers, sports catalyst and active-controlled quad tailpipes rounds off the major powertrain upgrades. A unique three-way adjustable suspension setup helps to deliver the optimum balance between stability and comfort. The exterior modifications include a deep carbon fibre front splitter and side skirts, prominent 'Super Snake' bonnet, a carbon fibre boot lid with integrated flip-up spoiler and a sculpted carbon fibre rear valance that houses the large exhaust tips.   Inside, the Sutton CS800 features a custom installation of the Ford Performance Recaro seats (specially fitted with electric height and reach adjustments) – which are not usually available on standard UK cars – as well as a bespoke carbon fibre dashboard, the short-shift gear lever and exclusive Sutton badging throughout, including CS800 stitching on the Recaro seats.   Built to order, however each CS800 differs slightly and our vendors have kindly provided further details of the car we are offering today. Based on a 2018 S550, sixth generation Mustang Fastback, it's a rare Clive Sutton 5-litre CS800 two-door (ULEZ EURO 6) in Shadow Black Metallic with bonnet scoops, carbon rear spoiler and carbon fibre side scoops and sitting on 20" Vossen VFS1 10-spoke alloys in Satin Black. Engine upgrades include a Stage 2 Whipple supercharger, upgraded intercooler, new injectors and a larger throttle body. A new exhaust system with long tube headers, sports catalyst and active-controlled quad tailpipes contribute to the output of c.825bhp. Other mechanical upgrades include a limited-slip differential, 20/28mm drop lowered springs, and front and rear brake calipers in racing blue.   The specification sheet also lists a full black leather interior with Recaro front seat custom-embroidered seat backs, interior lights upgraded to LED, Sync Iii SatNav, rear camera, Shaker audio system, rear parking aid, rear seat delete, Sutton bespoke performance steering wheel, ambient lighting-interior and Premium Marketing Trim. And there's more - tinted rear lights, GT350 wings, black badges, daytime running lamps, dual power fold-back mirrors, auto Hi-beam headlamps and hill-launch assist.    A 825bhp, all-black, customised, two-seat Mustang may not be on everyone's shopping list but if it is, or maybe could be, come along and view the car at our Supercar Fest sale and prepare to be impressed.
