Once again, I have only Honda experience to add here so far. There is a hatchback "duckbill" available, and I also am a cheapskate. Found one of those for $100 vs. >>>$100 for a real wing, thought I'd give it a shot. Made a HUGE difference at VIR right where I needed it (upper esses), and did not decrease my end-of-straight speeds at all that I could detect from the stock speedometer. The shape of the Miata is very different, but I imagine the aerodynamic principle applies the same. I say give it a shot.

Finished my splitter today. 12mm birch. Alum brace with turn buckles hidden away and the rear is held onto the subframe with riv-nuts.



Me looking like a tard... blink for the camera everyone. it can hold my weight although I think 2 more turn buckles on the front would be best.

If it holds your weight, you're done. Be warned that my splitter added as much downforce in the front as the wing did in the back. No lip spoiler is going to match a full aerofoil, no matter how big it is.

Good to know. It flexes a tiny bit at the edges which I wouldn't mind surdying up a bit. Also I'm jumping right to an apr.

Now were getting srs.





Heading this weekend to the Bible Creek Hill Climb in Oregon...

Ignore the terrible driving but this is the road... A lot more corners than Knox Hill Climb I did earlier this year... seems to be a much slower road.

I riv-nutted two holes in the subframe. Splitter goes to the center line of the front wheels.

I took the car for a quick spin on the road today and at freeway speeds the car feels quite a bit more stable. May be a placebo effect but I'm pretty sure I felt a difference. The car didn't want to walk all over the road anymore and felt more planted.

block off the holes in the lip unless you're using them for brake ducts. now its time for tire deflectors!

For this weekend I'll just use some racers tape, but eventually I will do something similar to bbundy and hustler and use it for brake ducts.
