I am in the process of having a purpose built wing made up for this seasons racing - wondered if anybody else wants one?
Basically it is the full width of the car (unlike the Lotus MS jobbie) and will be adjustable, and depending on how many I order it will cost in the region of �725 + VAT + delivery. It will retain the standard mounts, and will provide noticeable downforce and give less drag than the standard wing. The Lotus Motorsport wing retails at �850 + VAT.
If I have firm commitment (ie 100% cos its my cash on the line), then I will increase my order. I would also appreciate a deposit up front. A number of regulars on here can vouch for me…
(I will be doing this through Lanzante Lotus who won the first year of Lotus Roadsports, and who will be competing in this years British GTs in an Elise. Dean Lanzante is fully aware of this, and would rather this come through me so he doesn’t have to do any work )
It is my belief (and I may be wrong) that it would be legal for the road because it is aftermarket. Lotus would not be able to sell a car with that wing themselves. Bit like the 190 kit - Lotus could not sell the Exige 190, but could market the kit separately.
I’d like one. But I can’t really afford it right now
Have you got any figures (estimated or otherwise) for the relative changes in downforce and drag?
If I had the money/time I’d try to get a more efficient wing design to produce the same downforce as the standard wing for less drag. It would need to be full width, have big end plates, and have a lower angle of attack. It should also have a sharper trailing edge. Anybody think they can make one for 2-3 hundred quid?
Unfortunately the price is pretty fixed - although when I get mine I’ll sell you my standard Exige wing and you can mount it above your existing one to provide double the downforce
Um - to be honest I don’t know. Dean originally specced it for their GT car, so its going to be up to the job. There are 3 ordered at the moment including one for myself, Dean is happy to increase the order but not spec a new wing…
If there are more questions about it I’ll hold fire until there are several cos I don’t want to be bothering him every 5 minutes!
Isn’t the std item (that I must admit I do really rather like the look of) give about 80kgs at a ton?

Actually no, not even that much. The figure of 80 kilos applies to the whole car at 100mph.
The official figure is 45kilos at the rear and 35kilos at the front.
How much of that 45 comes from the wing and how much from the diffuser/overall shape of the car I don’t know.
I have a question about the wings, just for curoisity’s sake. Would you need to add downforce to the front of the car after increasing the downforce in the rear by so much?
I know this is more than likely a stupid question but please bear with me, I am fairly new to Aerodynamics.
Sam, that’s what the posts above regarding the front splitter are refering too. Lotus had a bigger wing and better front aero (usually refered to as the ‘Motorsport splitter’) on the race series cars.
With that amount of extra rear downforce I think you’d be mad not to improve the front. You’d understeer off on the first mildly quick bend without it!
