Rear bi-plane wing
Discussion
Hi Nick - I am trying to work out where the main wing should be mounted
in relation to the small "winglet"
I assume that there should be some overlap as I have the two rubber winglet supports
that prevent the winglet deflecting when positioned between the wings?
Glad to hear that you've still got the SR4 - any racing this year?

There are three rubber grommets that keep the two wing elements apart, M4 or there about screws go into these from top and bottom. It looks like they are screws rather than bolts so probably screw direct into the grommets. Hope that helps, I have some rubbish camera phone shots I can send you tomorrow but not sure they will tell you much.
Still have the car but it is advertised at the moment, will see what happens with that. Thinking of a caterham roadsport car to allow an occasional road blast and race as time allows.
I see you are having fun in the club cup, almost choked on my tea the other night when I turned on motors tv and who did I see other than yours truly grinning back at me, looked like you had a good day out - snett.

Hi Tim
Here's a photo of the fab ally main plane & gf winglet (both genuine R) that we had on the SR4; the winglet if genuine will have depressions where the screws go/sit; the fixings into the main wing are on the rearmost line of rivets. You really need the bi-plane end plates to get the relationship between the two spot on. As Nick says, my recollection is that the screws go in from top and bottom (top of winglet & underside of wing) and the grommet does the jointing together; think the grommet has a metal tube insert.
The all carbon biplane wing (when I say all, I meant the main plane and the winglet being carbon, as the end plates are usually ally) is completely different; extra rigidity of the components means the three screw grommets are replaced with two carbon anti-chatter blocks bonded to the main plane, which the winglet just sits onto. I could send you pics of that too if you want.
