Jeez, I’m almost tempted to take the wing off mine! I’d love to see some figures for how that would affect the balance. I don’t mind losing a little downforce, but I’d hate to have lift at the rear.
Obviously it worked for TarmacTerrorist, but I’m guessing he’s not running at the standard ride height/rake angle.
I must admit, I do actually rather like the look of the S2 Exige sans wing.

Get yerself a proper manly wing, dude, then you’ll be slower down the Kemmel straight like Jonny Fox!

Fixed that for you

I wouldn’t drive down the Kemmel straight if I were you 
All this talk of aircraft reminds me that I’m waiting for my new desk clock to arrive! New, & as used in Mig fighters 
That’s cool. Sure you’re not tempted to mount it in your car?

VERY cool!
I want one!!!
Where did you find that piece of engineering then!
Cheers Brendan. I think it’s pretty cool too!
Apologies for thread hijack, Pete.
Where did you get it from!!!
(and dont say a bloody MIG!!!)
That is proper man stuff !!!
Good old eBay although I only found one “new” one - got it for �105 including perspex stand.
There are all sorts available - go for it!
Getting back to MY bloody thread!!!
Just measured the 2 wings surface area.
OEM wing is 350 sq inches
MY10 wing is 460 sq inches
About 25% more area!
Piccy below… and a very nice paint job as well! 
Fit 'em both Pete!
More area doesn’t necessarily lead to more ‘lift’. Also, an increase in the ‘lift’ you produce simply means that you are also increasing the drag and therfore the amount of power required.
IT IS NOT STRAIGHT FORWARD…

The 2010 wing will be more efficient producing less drag per square inch of area because of its higher aspect ratio …
So I reckon it,s the better wing to have …
Now who,s gonna be first to fit two and go biplane ??
In this case, yes!
Mr Bernoulli says amongst other things that
Cl (and Cd) = 1/2 p V2 S (The Co-efficient of Lift (drag) = 1/2 (air density) * speed squared * Surface area
The biggest thing that increases lift (and drag) is therefore V2… speed.
Given a constant wing chord (width) as is the case with the 2 wings in question, as JFK has said the aspect ratio is increased with the increase of 25% in surface area. This WILL increase lift much more than the drag as a high apsect ratio wing is much more efficient.
But the relationship between lift and drag is complex and depends amongst other things on the wings ‘angle of attack’… AOA is the angle between the mean chord line of the wing (a straight line drawn from the leading edge to the trailing edge) and the relative airflow. I have not seen much video about what this angle is on a Lotus, but it is quite shallow (guessing 10 - 15 degrees) so the amount of lift generated over the extra drag would be considerable. (drag does rise steeply as you increase the AOA)
Anyway, all of this is quite silly really as the Exige/Elise is about as aerodynamic as a brick (too short!) so drag is high anyway.
TBH, lots of bar talk… but I reckon the MY10 wing will offer more downforce and now I have had it painted I think it looks better too (yes the car also looks pretty cool with the wing off!). Time to get it fitted then!
As for Bi-plane thoughts, NOPE!
Just looked at this thread - what the fook is going on ??? 
Turned into a fooking physics lesson and I failed physics !!!
I’m actually suprised that nobody has looked at the impact of the new V old wing when driving in reverse !!!
Surely the old wing would be much better in those circumstances !!!
Just making sure we thoroughly cover all angles (pun intended !!!)
Kept the white lab suit though, didn’t ya?
Nice !!!
Don’t forget that the shallow angle of attack, is partly due to the cars shape. If everything is working as it should, then the air/wind direction is slightly down at the leading edge, as its following the slope of the engine cover from the roof.
Bet it isn’t tho with the mass of mesh on the top of the enngine cover, venting hot air from the engine!
Try taping over the vents and see if things get better. Not for too long though, just in case!!
Wow this thread is mad, lets get back to the most important point…
Which one looks pretty?
Wahey, steady on Brendan, I accept that my comments were a bit glib but that’s a frosty detailed disection
Maybe I should have concentrated a bit harder in my fluid mechanics lectures :sleep:
I’m not an aerodynamicist but I do understand force vector resolution and caveman logic. Anway, I’m signing out of this debate :whistle:
There’s another techincal reason why I have had to take the rear wing off my S2…it won’t fit on the trailer with the overhead tyre rack.
