The Wing Shop

The Wing Shop

The Wing Shop 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 Services Ltd (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 Wing Shop/DJ wing customers, if required. Please read on for further information.

Downforce and drag data are available for our most popular packages at Wing data. Please enquire about other variants that you are interested in.

SM153 - Front wing main element, 275mm chord, maximum span 1700mm, 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 aplications 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 Servies 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 The Wing Shop.

Need help with your wing selection?
Please go to our Advice page or get in touch via our Contacts page, and Simon McBeath*, the designer of these wings will be happy to help you with the right wing choice fro our range for your car. (* Author of Competition Car Aerodynamics, please see Books and Aerobytes in Racecar Engineering, please see Magazines)

Why choose our wings?
We believe they offer an unrivalled blend of aerodynamic performance, low weight, structural integrity and aesthetic quality. Check out some of the successful customers using our products on this page and take a look at the Facts and Figures page.

The wing profiles, designed by The Wing Shop's Simon McBeath (author of "Competition Car Aerodynamics", click on 'Veloce Publishing on the right) have either been evaluated in the MIRA full scale wind tunnel, and/or by computational fluid dynamics (CFD). Analysis of all this information has provided valuable technical support and development data. We have also benefitted from university-based R & D projects. And we are able to analyse our wings in ANSYS CFD software.

Free 'whole car' aerodynamics advice!
When you order a wing from our manufacturing partner DJ Racecars, Simon McBeath also becomes available, should you require it, for up to a couple of hours of free advice by phone or email on the aerodynamics of the rest of your car, once a payment has been made to DJ Engineering on your wing. This service is offered to not only help you select the right wing, but to help to ensure that it is deployed on the car as it should be, and that the rest of the car's aerodynamics will allow you to get that all important aerodynamic balance as soon as possible after you hit the track! But do please note that this offer is only available to customers who have made a payment on a wing ordered from DJ Racecars.

Just some of our wing applications
Time Attack
During a visit to the MIRA full-scale wind tunnel to gather data for my Aerobytes columns in Racecar Engineering magazine in Spring 2013 we invited two very well known UK Time Attack contenders along (whom DJ and I had met when supplying them wings), one of which was the latest and much anticipated offering from Roger Clark Motorsport, 'Gobstopper 2', otherwise known as the latest Subaru Impreza project from this world renowned company, who won the UK Time Attack Pro class in 2008 and 2009 with 'Gobstopper'. Unlike its predecesor the car features an aggressive and well thought through aerodynamics package, with an SM/DJ '203' dual element wing on the rear. RCM directors Matt and Ollie Clark were present to observe and work on the car during the session, and much useful information was gathered. During 2014 Ollie Clark and 'GS2' went on to win the Pro Extreme class in the UK Time Attack series.

In late 2019 images of 'GS3' were released by RCM. This fabulous projectile, based on the Subaru BRZ, has an aero package designed by Andrew Brilliant at AMB Aero and features an SM/DJ triple element rear wing.

And in 2013 we welcomed Sasha Anis and his gorgeous Nissan 350Z on the Canadian and north eastern USA Time Attack scene into the Wing Shop fold. Sasha runs a dual element SM/DJ 183 wing.

In January 2019 we invited two more Time Attack wing customers along to MIRA, Super Lap Scotland 2018 Champion David Long (Caterham) and Simon Roberts (Noble). The session enabled improved optimisation and in David's case this translated into an outright win at the first SLS event of 2019!

UK Hillclimbing - wins and records
Wing Shop wings continue to score outright and class wins on the British Hillclimb scene. Alex Summers (DJ Firestorm) had an excellent 2021 season challenging for the overall British Hillclimb Championship and finishing second overall.

Pikes Peak Hillclimb
Among cars running our wings at this world-renowned event have been the TRD/TMG electric Radical EVP002 in 2013 and in 2015 & 2016 Jeff McPherson ran his awesome Porsche 914 with one of our triple element rear wings. Then in 2019 Robin Shute took his turbocharged Wolf-Honda sports racer to the outright win, the first Brit to do so, using SM/DJ wings!

SCCA Autocross Nationals wins for Wing Shop designed, DJ-made wings
Dan Wasdahl from Massillon, Ohio in his BBR Phantom DVS-1 took his sixth A-Mod Championship win with Wing Shop/DJ wings at the SCCA Solo 2 National in 2014, also picking up FTD again. Dan didn't run in 2015 and just missed out on the win in 2016, collecting second spot.

The development of the wings on the BBR Phantom was featured in Racecar Engineering in August 2007 (V17N8).

Fred Zust from Tempe, Arizona once again collected the X Prepared class win in 2015 in his Blackwatch Racing Lotus Elise, and Clemens Burger from Noblesville, Indiana took 2nd in B-Modified in 2015 in his LeGrand having won the class in 2009 and 2010.

For 2020 we welcomed Kyriacos Panayiotou and his B Mod LeGrand into the fold with a triple-element wing set based on the SM172 main element at the front, balanced by a 'quad' rear wing set using our ultra-high downforce SM203 main element, all within the maximum permitted 8 square foot rule applicable to sports racing cars in this class.

Podium at Indianapolis!
Having taken the SCCA Southern area F. Atlantic title in 2021 Dave Zavelson travelled from home in Austin, Texas up to Indianapolis in late September to tackle the week long SCCA National Run Offs for the first time. Prior to the event we ran some low drag wing configurations through CFD that Dave applied to the car specifically for this track to try to give him a ball park set up for the start of qualifying. With mixed conditions and traffic throughout the three qualifying sessions, Dave qualified a very respectable 7th. Then a clean race saw him stay out of trouble, unlike some ahead of him, and he finished a delighted 3rd to secure a visit to the podium. Many congratulations, Dave. We hope to work with Dave on the correlation data he now has for an even better set up in 2022, and illustrate the project in a Racecar Engineering article at some point.

Scandinavian Clubmans series win!
Many congratulations to Svein Langholm and Kjell Bodin on their 2013 Clubmans series win, with Svein driving and Kjell constructing the latest superb Bodin 12 racecar, featuring an SM/DJ 183 dual element rear wing. Kjell reports that with much help from Svein's hard-working mechanic John-Erik Karlsen they 'beat all the Mallocks, Mk 35, Mk 31, Mk 29' adding with typical Scandiwegian understatement 'rather nice feeling I must say!'

And in UK Clubmans, 2015 overall champion Alex Champkin mounted our new 'SM132' wing on his Proto class Vision for 2016.

The Wing Shop and DJ Engineering win the 2012 Goodwood Festival of Speed!
The 'Top 20 Shootout'-winning Chevron GR8 GT3 V6 driven by Anthony Reid at the 2012 FoS was equipped with a Wing Shop-designed, DJ-manufactured '183' single element high efficiency wing. Reid and the Chevron fended off challenges from an F1 Leyton House CG901B driven by Gary Ward, a Silk Cut Jaguar XJR-8/9 driven by Justin Law, Michael Bartels in a Maserati MC12 and Michael Krumm in a Nissan GT-R GT1.

Wing Shop wings and SM AeRo Techniques selected by BBC TV's 'Top Gear' programme!
For its assault on the Britcar 24 hour at Silverstone in September 2007, the BBC's Top Gear team contacted the Wing Shop to request a rear wing package to go on the BMW 330D for the event. And the splitter and wing concept came about from associate producer Grant Wardrop's researches in Simon McBeath's book, Competition Car Aerodynamics. The wing kit was delivered and fitted in double quick time by DJ Engineering to meet the incredibly tight timescale of the car build, and the splitter was also installed by DJ. Simon McBeath attended the first test prior to the event to ensure wing tuning data was available and that the package was balanced to The Stig's liking (The Stig is the famous and formerly (!) anonymous racing driver on the Top Gear Team). And DJ personnel were in attendance for the duration of the event. Team Top Gear finished third in class (out of five) and 39th overall out of the 60-odd cars that entered. The story was originally broadcast in an excellent edition of Top Gear in October 2007.

Wing Shop/SM Designs wings have won championships in single seater and sports racing categories as well as finding applications on track day and even road cars. And many other Wing Shop customers can boast of wins and records as well as just plain old performance improvements!

Our pre-preg carbon composite aerofoils feature a market leading blend of strength, rigidity, lightness, damage-tolerance and aerodynamic performance, and as such offer excellent value for money. They also look great! So why shop anywhere else?
