Mazda MX5/Miata NB & NBFL - Front Tire Spat

I wanted to design some aero improvement (drag reduction) add-on to my Mazda MX5 NB but without sacrificing the exterior design of the car, so I decided to design these front tire spats.

It's known that one of the biggest contributors to aero drag in a vehicle are the wheels, and while aero wheels / aero covers have quite a big impact on the exterior look of the car (which I strongly want to avoid, since I absolutely love the style of this JDM budget friendly gem), front spats are, mostly, hidden from the naked eye and can have quite a significant impact to reduce the horseshoe vortex and high speed air hitting at the front of the rotating tire. Nowadays, pretty much all the cars have front tire spats, including NC & ND, due do their significant impact on reducing the drag (improving fuel efficiency).

I ran some CFD to check the impact, and these reduce the CD (Aerodynamic drag) by 11cts CD, which is quite a nice improvement.

I printed in TPU 95A to avoid it breaking if it scrapes or hits something, but been using these for more than 8 months in my Coilover MX5 and had zero collisions.

It bolts directly on the 2 fender liner bolts, so it looks pretty much stock and it takes just 1 minute to install.
