We are currently testing V3 S2000 rear brake ducts because the V2 are also failing at a higher rate than we are comfortable with. They will be tested this weekend at NASA Champs and then be made available if everything goes to plan! Right now they are much more robust and have less parts than the current V2 ducts, with a smaller footprint as well.
Here is a look compared to the old V2 duct:
Also, a lot of parts will no longer be restocked when current stock is out. All current endplates will be the last batch because demand for them is not enough to keep them in stock. Once they are out I will post up DXFs and STPs so people can make them themselves.
Almost all parts are also currently on sale to try and clear out some old stock.
