Cycle vs Clamshell
Other than aesthetics, are there any differences between the two types of Front wing?
Its not massively important to me as I'm hoping to get started later this year and looking at about 18-24 months to build but I prefer the Clam
shell style wings and was wondering if theres anything I needed to know.

clamshells can act a bit like parachutes

I think the clamshells can produce quite a bit of lift at high speed.

You can't pass IVA with clamshells, they won't meet the wheelguards requirements.
You'd need to go more Morgan-esque in order to sufficiently enclose the wheels:

So they'd have to come down at the front abit?
Would it be a problem if they were swapped over post IVA? What kind os speeds would they cause me problems above, I wasn't really planning on
going much past 70?

You might change your mind when it's built and on the road/track

I prefer the clamshells hence me sticking with them. I think they are more sympathetic to the original design although if I had a more modern looking
locost then cyclewings would be the way forward!
Ive done nigh on 120 at throckmorton airfield and didn't noticed any untoward effects but then I wasn't really looking for any lol.

I have them fitted on mine, noticed lift at 70 which got worse at 90.
Felt like the front was about to lift off the floor.
Am going for cycle wings as close to the tyres as I can to try to reduce the problem.

I have a black set off a Westfield that I have been trying to get shot of for about 2 years, too good to dump or burn but un loved in the for
sale or "come and take 'em awayfor free" sections,
It's nice to know there's still some clam shell afficianados out 'n about.
I mayhave a cunning route to get them down towards Kent as I have a mate in Westerham and by your build schedule you wouldn't be needing them
next week.

i had clam wings for about 3 years and liked the look alot, but thought they held the car back with a lot of drag.
changed to cycle wings over the winter and the difference is very pleasant a lot less drag (high drag high petrol costs) and the car is smoother at
speed.

Cycle wings do tend to suffer from stress fractures in their supports, caused by vibration as they flap about. Because of that I fancied changing
over to clamshells, but I found that they're very hard to buy - very few people make them nowadays.
I found an alternative solution to the cycle wing support fractures... but that's another long tale...

Would it be difficult to build the car so you could have both as option, and just bolt on the ones you want at that time?
I think they make the proportions of the car look better.
