Something relatively inexpensive, holds up to weather/sun, and somewhat durable. Bed-liner or similar polymer is pretty popular, which helps costs.
    That's super, I just met with a friend from Raytheon today oddly enough.

    Thanks! I thought I saw a message from you, but now its gone I will PM you

    Quick thought, what reasons are there to have that splitter so short and not go back further towards the front axle? The oil-pan is pretty low right, but you can cut around that. The reason I ask is because we've seen yuge gains on CFD data from extending the bottom of the splitter back as far as possible, on multiple chassis.

    We've(9LR) been testing several materials on our NA/NB miata aero packages. 1/2" polymer coated birch, 10mm alumalight, and tegris have seen the best results. We've settled on 1/2" birch coated with...... "rocket nozzle" polymer It requires less mounting points than alumalite and just a tad heavier. Not too far off weight after we did some stress-testing on the birch and removed the material...

    I do plan on continuing the flat underbody, so it'll connect to the splitter. I wanted to make the actual splitter separate so if/when it gets smashed I can just swap in a fresh panel. Also so I could play with lengths, mainly to make a shorter option for driving around town.

    Kinda reminds me of Line-x? I wonder how line-xed plywood would holdup... or is that essentially what you're doing?

    Yes big wang kits are definitely of interest... I was eyeing the "builders kit" as I'd like to make my own mounts when the time comes...

None of the local sign shops with dibond or alumalite are open on the weekends or weekdays past 5pm which makes it near impossible for me to pickup.

    That's a nice piece. I just fixed my computer and am looking for a "light" CAD program to do simple drawings for parts like this. Any suggestions?

    You might be able to get Auto desk inventor for students, it last 3 years. Just fill the form out and say your in community college.

    I also used a version of "Alumalite" called Alupoly from a local plastics shop for my front splitter. I ended up using a 3mm (approximately 1/8") thick version, but they also offer a slightly thicker version as well. I sent in a CAD template that I made and they CNC cut it in a day.

    The mounting is not the most ideal setup for fully functional aero as I just bolted to my IS lip every 6-8 inches, but it does feel very sturdy up to speed on the highway. I would also need to block the front gap on the lip for additional functional down force. This version overhangs about 3", but I also have a 5" version that I will eventually try when I decide to make the switch to a rear wing.

    Looking for advice on splitter materials and construction. I made v1 out of mostly 1/8" ABS, angle aluminum and 304SS - the aluminum and SS used for brackets and support. I liked the ABS because it's flexible and is already black, but now I see it's just a bit too flexible to be a sturdy aero component. Currently looking for alternatives. I've seen alumalite suggested and used. I also found a local source for dibond (similar to alumalite but with a solid poly core). And I'm also considering sheet aluminum. What materials have others used successfully? My untested thoughts are a toss up between all three. Biggest question for either alumalite or dibond is 1/8" vs 1/4" thick. If I went aluminum seems 1/8 is plenty strong. Only concern against aluminum is that if I smash it on something it will bend and be a pain to flatten vs dibond/alumalite which seem to a be a bit more durable in that regard. As far as construction design goes I initially mounted the splitter to the bottom of the valence by way of an ABS skirt which clipped into the IS brackets in the valence, and screwed into the splitter through angle aluminum. While it looks good, it's not durable nor very structural and is prone to popping out of position with minor scraping/rubbing against the road/driveway (which is kinda what I intended - but too much). I'm trying to engineer some planned failure mode into this whole thing so that if I smash the splitter on something like a cone or off-track adventure I don't also smash the valence along with it. So in other words I want to mount both splitter and front lip separate from each other. Splitter mounted to the frame rails with brackets + support struts and some (easily broken) plastic clips to the lip. Then the lip mounted to the valence with sturdy brackets. I hope that this will allow the splitter to be sturdy enough to provide actual aero benefit without damaging more than just the splitter in an "incident". Thoughts?

    Thanks for posting that link. Read through a few pages while sitting at the trade show booth twiddling my thumbs...

    Also checked out Nine Lives Racing's website and it looks like they are working on an e30 kit: https://9livesracing.com/products/e30-big-wang-kit
