Default SuperMiata airdam @ 949 Racing

IWe now have the SuperMiata airdam in stock for the NB1 (99-00). 90-97 will be ready in about 6 weeks. NB2, (01-05) in about 8 weeks.

The design goals were, in order of priority:

1. Reduce aero drag
2. Reduce aero lift
3. Be inexpensive
4. Not destroy the front body work if it gets hit
5. Be lightweight
6. Be easy to add an undertray or splitter to
7. Improve cooling
8. Not be too fugly

This is a racing part so it comes with no warranty or instructions. It fits very well but don't expect a show car piece. It's designed to be lightweight and flexible so as to come apart if it gets a direct hit. It will not take the bumper (and everything attached to it) along with it.

I recommend three small 4m nut/bolt fasteners to attach it. One in the radiator opening, one on each tip near the fender. Small washer on outside, fender washer on inside. You want the fastener to pull through the FRP and not pull the OEM bumper off with it. The underside has a small 2" flange to rest an undertray on or attach a splitter to.

In testing, it provides a good aero balance with an APR GTC-200 wing set at 0~8 (relative to groundplane) in the center. To increase front downforce, one could add a splitter between 1-4". I do not have recommendations, tutorials or instructions on splitters. That's a real DIY experimentation thing and the subject of another thread.

We even tore one off in testing and it fractured exactly as it was designed to. Came off without damaging the bumper skin, fasteners still attached to car. So, no nuts and bolts on the track for somebody to find with their $250 Hoosier. Until then, it was solid and balanced the GTC-200 wing. Mission accomplished.
  • Hand laid FRP construction (fiberglass)
  • 4.5 lbs
  • White gel coated finish (not available painted)
  • Diverts airflow around 225/45's on 15x9 6UL's
  • 2.5" above ground at 4.25" pinchweld height

Nice price. Very tempting when the NB2 version comes out.

I'll be very interested to see what the 90-97 looks like once it's done.

Theyre all the exact same final shape. Same minimum height at the same pinch weld.

Ok, so the only difference will be the inside to have it fit on the early bumper?

Good to know... def going to be interested when they become available!

For the time being, no. The picture and info published should give anyone the info they need to make a decision. If it's a style consideration, you're on you're own.

Someone on NASA forums called it the Amish airdam.

That shape is our solution for masking as much of the front tire as possible while staying within NASA and SCCA rules with the least aero drag, lightest weight and best breakaway characteristics. Like an F1 winglet or DTM rear fender diffuser, it ends up looking odd but works.

That's KenO who drives the "TTB" E46 M3 that makes 340whp, AST 5300's, and 285 Hoosier R6. Notice I said "TTB".

Canards - please.... saw the thread over there... I wouldn't be suprised if Greg makes it a 6pt Mod as the frontal slope could induce downforce (?) (+3) , and then slap another +3 as an airdam - then probably another 3 for just putting it on a miata ...

So how flexible are the sides? Think they could cover up my fat tires when stretched?

From an aero design standpoint it is really good that it extends past the front bumper. I think it will sell well in both NA and NB versions. As stated before, it does look like it has a beard. It reminds me of Air Israel from the movie Airplane!

Will it hold up to traffic cones at 70MPH?

No idea. Not what it's designed for. Let us know if you find out.

Yes. Yes, of course.

I'm sure Faeflora meant yard gnomes.

I think you will sell lots of these. The stock nose design on both the NA and the NB lends itself to air pushing up on the underside of the bumper and lifting the front end. This is nice.

Looks like a smoothed-out version of my ISC airdam (same air dam as the white one on Emilio's car in his sig?), which the guys in my paddock have come to call "Abraham Lincoln" or "the Abe Lincoln chin".
