Hey all. Just asking a small question here. For the front wing, we can clearly see that it has much potential to be fooled around with. Cascades, the actual flaps, the endplates can all be changed and we can see this. But I think for the rear wing, asides from the f-duct and also the Renault McDonalds wing, there doesn't seem to be much in the name of innovation. I don't think we really see anything other than that other than a few endplates (which are seemingly converging to the same 2 or 3 designs anyways) Is there actually room for much more, if any, innovation and development here?
