Make and model?

1. The 'spoiler' you specify won't do much. An example that would get you the most ROI with a fiberglass cap might be the Golf GT-W12-650:

Generous ducts on three sides. Else something with better access?


2. A study on the effect of exhaust position on drag and lift (08-29-2024) -- Logic

3. This will benefit from a full bellypan. Start the divergent angle as far forward as possible. A proper diffuser has strakes and fences -- an extreme example.


Make and model?
