SM / DJ Carbon fibre wings
The Wing Shop, under aerodynamics writer & designer Simon McBeath of SM Designs, has designed a range of racecar wings for motorsport and track day applications that are beautifully manufactured in autoclaved pre-preg carbon composite by manufacturing partners DJ Engineering (also known as DJ Racecars) using polished aluminium tooling to achieve world class results. Our wings are used by some of the top competitors in a wide range of competition categories around the world and of course feature on DJ Racecars' superb hillclimb single seaters. As well as helping you to select the right wing for your application, free 'whole car' aerodynamics advice is also available to SM/DJ wing customers, if required. Please read on for further information.
AVAILABLE PROFILES
Downforce and drag data are available for our most popular packages on the Wing data page. Please enquire about other variants that you are interested in.
SM153 - Front wing main element, 275mm chord, maximum span 1700mm, now replaced by the SM1425, see below.
SM1425 - Front wing main element, 300mm chord, our replacement in 2022-23 for the SM153 above for single seater applications in single-, dual- or multi-element applications, designed to operate in ground proximity; can be configured to balance most of the rear wing applications below. Available with simple flat end plates or our 100mm wide 'Vortex Entraining End Plates', or 'VEEPs', for a significant downforce increase.
SM172 - Front and rear wing, 225mm chord, maximum span 2100mm, medium downforce wing originally designed to suit applications where chord is restricted through preference or technical regulations. (With a 5mm Gurney it produces similar downforce to the SM183 described below but with slightly more drag.) Can be provided in dual-element format. Also suitable as an alternative front wing main element in some applications.
SM183 - Rear wing, 300mm chord, maximum span 2100mm, medium downforce, low drag, hence very high efficiency (downforce to drag ratio) in single- or dual-element applications. Our original wing design, and still going strong! Specified by well-known luxury road sportscar manufacturers for their 'track' variants and also used in a wide range of applications from saloons, sports and GTs including OEM track and racing variants, to sports racing cars and single seaters. Easily balanced without needing an extreme front end aero package (advice available to our wing customers). Available as a high efficiency dual-element device with a very wide operating range. Also available as a high downforce, high efficiency hillclimb single seater ‘quad’ two-tier set up.
SM132 - Rear wing, 300mm chord, maximum span 2100mm, high downforce, high efficiency rear wing designed for saloon, GT and sports racing applications where a single element wing is either mandatory or preferred in order to balance a restricted front end aero package. A wide range of successful uses including circuit, hillclimb and Time Attack.
Also available as a potent dual element device, but requires a strong front end package to achieve an aero balance (advice available to our wing customers).
SM203 - Rear wing, 300mm chord, 2100mm maximum span, high to ultra-high downforce rear wing designed primarily for dual and multi-element applications where maximum downforce is the objective and drag is not a concern. Originally designed for UK hillclimbing but also highly successful in SCCA Autocross and in some Time Attack applications.
Typically requires a really strong front end package to achieve an aero balance (advice available to our wing customers).
SM101 - 'Flap' profile, 120mm to 170mm chord, to work with any of the above main elements to create dual-, triple- or multi-element configurations. Can also be used as a small chord standalone wing.
Slat - Leading edge slat for ultra-high downforce multi-element configurations.
Sample prices (based on up to 1700mm span)
Main elements from approx. £1200
Flaps from approx. £500
Spans above 1700mm will attract a proportionately higher price.
CNC-machined mounting brackets can be affixed at specified lateral spacings; please ask DJ Engineering for the options and prices. The attachments to the car are usually manufactured by the customer, although if provided with suitable CAD, DJ Engineering can design and manufacture these as well.
Various end plate options available from simple aluminium plate to 'monolithic' carbon to structural sandwich core for multi-tier applications; custom designs also possible.
Please contact DJ Engineering Ltd for a price quotation for your specific application and requirements. Or if you would like guidance on wing selection then please contact Simon McBeath at SM Designs/The Wing Shop.
