Thought I'd start a separate thread on my track toy aerodynamics.
The standard WRC type rear wing is non adjustable other than removing the raiser blocks. I understand that if you remove the raiser blocks the wing element simply becomes a spoiler i.e. kills any lift. A better solution offering the possibility of adjustability is the TRD wing. The central wing element is secured to the end supports with two bolts through slots offering a small amount of adjustability. I believe that if the wing produces any sort of downforce then the bolts will slip on the slot. This is why race cars use end supports drilled with multiple holes.
Although I have a TRD carbon rear wing it turns out that it weighs exactly the same as the GRP version so I've elected to use the latter version obtained from Nibbles ST205 when he replaced it with a WRC wing.
I will probably stick with the standard centre wing section initially. If I need to tweak it to produce more downforce than available on maximum incidence a gurney flap is always an option. You can buy these with double sided tape here:
In the pic of the Supra below you can see the general idea of changing the centre section on this TRD rear wing which still uses the end supports. The wing here is a commonly available twin element design modified to fit with end adaptor plates. This design would likely give more downforce than the TRD+Gurney at lower speed.
More to come..........
