FAQ
How is this different from the endplates?
The endplates fence the edge of the splitter. These sit under it and expand, which accelerates air at the inlet and recovers pressure toward the exit. Different mechanism, same goal of making the front of the car work harder.
A diffuser is a vacuum cleaner, right?
No. A diffuser is a pressure recovery tool, and it is only ever as good as the air you feed it. If the inlet is not sealed and fed cleanly, the expansion downstream has nothing to work with.
Is the shape optimised?
It is the wedge geometry fitted to my car. I have not CFD'd it or run it against a baseline on a measured surface, so treat the geometry as a working starting point rather than a solved optimum. No downforce figure is claimed.
Will this fit my splitter?
These are fit-specific parts. They were sized for the AJ Hartman aero kit on a C8 Corvette. Check the mounting interface against the photos on this page and compare it with your own splitter before buying; other splitters will need work. If you are not sure, email [email protected] and ask about fit before you order.
