The front cooling is definitely a good place to look. Ducting the exhaust might be too much effort but the intake definitely could use some modification. If you can take out the grill, it should be easy to take some plastic sheet and foam and make a smooth duct with a smaller and more efficient opening.
I remember thinking about how to make the exhaust a bit better and my conclusion was that you can remove the stock plastic piece and replace it with a flat plastic panel with a thin slit cut in it and an angled duct above.
As far as the rear, I would just toss on the longest spoiler you can find (if it doesn't need to look really good, this is pretty easy to DIY: https://auroraautodesign.com/product...nb-miata-90-05)
You can try to mess with a diffuser but the lack of OEM paneling suggests to me the results may not be great. |
As for cooling, at current temperatures I postponed the idea of grille-blocking, but modifications to the ducting (or rather lack there of) are considered for the future, same as a flat underbody.
However due to the complexity involved in that, I won't be doing that now.
(also TÜV is coming up so I'll only do stuff they don't care about untill then)
As for the cooling intake, I am considering to fabricate a fiberglass insert for the bumper as well as some ducting inside.
Exausting it would likely work via the front wheels in that case as hood vents would cost me my trunk.
As for the spoiler, one as large as that would add a lot of drag.
My plans where going more in the direction of a small spoiler for a cleaner flow seperation as well as canceling out rear end lift.
The idea of adding a diffusor is tempting indeed, however due to drivetrain as well as exaust components, this would be complicated.
If the goal of the diffusor was to add significant downforce, it would need to extend quite a bit to the rear.
However my main goal here is drag reduction, so I won't need much of a diffusor.
