    Adjustable wing mounts.

    Race team head engineer wasn't happy with the rear wing positions on the mount supplied with the wing (standard multi-hole deal) so asked if I could make something with more adjustment.

    The answer was some small rigging screws (turn buckles), which of course necessitated a whole new mount.

    Needs a few minor tweaks but all in all it works well, rigging screws are easily turned with your fingers through the sweep to give between 8 and 18 degrees angle off attack.

    Needs more beef to support the rear mount of the wing. Also, hopefully they remember to do the front mounts back up after adjusting...

    You reckon it'll bend ? At the thinnest point it is 22mm and the material is 5052 @ 5mm (x2 per upright). This is going on a 1.5l super production car, not a v8supercar.

    I think The Lightyear is referring to the bulk of the mounts, and he'd be right if it were strapped to the bootlid of a sedan/coupe rather than the hatch of a Mazda 3.
    I guess if you're not seeing much over 100mph down the straights then it's not much of an issue - how coarse was the old adjustment setup?

    Ohhh I did not consider drag from the actual mount saying that I ran my idea past the head engineer beforehand and he certainly did not express any concern.

    Hole spacing's on old uprights are 2.5 degrees apart which were not ideal, It is possible this new set-up will be no good but that why we rent both the local race track and a military airstrip and do aero testing and log km/h vs kg/f with each change in angle.

    From memory (albeit vague) I think the cars top out at 220km/h.

    Why were the turnbuckles needed?

    So with more grunt we can dial i some more downforce, not sure what to do with the front splitter as making it beefier will result in more weight and as these things are diesel more weight in the front is bad.


    Here's the current front splitter, made from 4mm marine ply and 1.5mm ally, works really well in this application.

    any suggestions on how to improve this (stronger/more down force), Keep in mind they are disposable (new splitter fitted every outing x 2 cars, Ban Saeng speed week is coming so cars will go out 8 times Between practice and racing).

    You could put end plates on the sides to help with more downforce at the front.

    4mm seems pretty thin compared to what I see most using, I would have expected 9mm. Perhaps something more substantial would last a whole weekend?

    I've got a sample of Monopan honeycomb panel coming, it's 4.5kg/m2 for 17mm thick compared to your 4mm at around 3.1kg/m2.




    Availability is the problem I guess. Another option is 6mm honeycomb aluminium composite panel.

    Neil_se,

    the main issue is grinding the heads off the rivet heads underneath, hence a new one is fitted for each outing (whole splitter costs us about $10.00) but the outer edge cops a beating as well.

    Monopan is not available here but we do use it, we import from Germany in a thickness of 30mm for other projects we do.

    Breadboard material can be used under the splitter.

    Last lot of splitters I made were from a 6mm thick plastic material, A small 100mm x 100mm sample felt a lot more rigid than the 4mm marine ply but In practice though is was way more flexible and wore out very quick and was expensive ( $90ea for each splitter).

    What do you mean under the splitter ?

    I imagine he means as a rubbing block to protect the rivet heads?

    Whatever you go for the weight would have to increase, surely the 4mm ply flexes significantly? 9mm ply + countersunk fixings would be simplest.
