Post your DIY aero pics

I would prefer some sort of plastic just bolted directly to the side, the plastic will be able to flex when bottoming/high centering and will spring back unlike the aluminum. The stiffness of your plastic will have to be experimented with soft enough to flex without upsetting the car, stiff enough to not flex in due to aero pressure. I'm thinking ballistic nylon might be a good choice since it will be lower wear but you'll need to experiment with the thickness to get the right stiffness.

you could try this plastic?

I use Circle Track wear strip material, its pretty much just thin abs plastic. Its very durable I daily drive with it on the front scraping things everywhere and its still all together in one peice. Im working on sideskirts myself with the same material, using alumalite extensions with the abs seal.

Anyone here dabbled with side skirts? Trying to figure out how I want to approach mine. I have side exit exhaust, so I'm thinking thin aluminum sheet bent into a 90 to come out and down from the rockers to decrease ground clearance, with a possible taper near the front wheels (again, take a look at the Peugeot T16). Optionally, I can frame them out of aluminum tubing or brake line and make a light pair out of fleece/fiberglass, but it would sure suck to go through all that work and then lose it in an off-track excursion. Would also need some sort of insert to protect it from the exhaust exits, which is why I'd prefer the aluminum.

I'd rather run quick latches on them. The skirts are going to be consumables that you replace and its easier to swap the quick latch buttons to the new skirt than the dzus. BUT if you tear a skirt completely off and dont recover it, you're out $25 x however many quick latches you put on it, vs $5 x however many dzus fasteners. Though, in theory you should still be able to drive onto the trailer with these because they should flex.

In my opinion all that is doing is acting as rock/mud guards to protect your paint and disturbing airflow behind it so the air down the side of your car is more turbulent and unattached

I would think that you want the rear open to help air flow out of the wheel well.. and you want something to deflect air around the front of the tire.

1993ka24det's separate discussion thread works but now we have two threads discussing the same topic. It would take a mod a few hours to clean up, move posts, splice, merge or whatever.

Borderline in terms of "aero" but it deals with airflow so I'll throw it in to get the thread back on it's original format/focus:
Dollars spent: $0 at time of construction (used materials laying around)
Hours spent: 5
How effective: Will find out this weekend
*update*: worked great, brakes performed great and never overheated
Materials used: Aluminum sheet, 2" aluminum intercooler piping, rivets
Tracks tested on: Going to Spring Mountain Motorsport Ranch this weekend
Race/TT class built for: Miata Challenge & Super Miata
I wanted to get the brakes ducted before the next event, but not enough time to order ducting for the airdam and get it here in time...
Originally thought of making these out of a composite but then discovered that I was out of resin. So looks like I'm making it out of aluminum! Scrounged around, found a sheet of a thickness I liked for this, and also some spare 2" intercooler piping. That'll do.
Got a concept worked up in my head, made a template out of construction paper:
Transfer to aluminum, then get to cuttin':
Next, brush up on my origami:
After a riveting time with the rivet gun:
Trimmed the front of them to the same contour as the airdam and then riveted to the sides of the radiator ducting:
It would have been easier/faster to make these attach to the airdam, but the whole point of all the dzus fasteners on the airdam is for it to be able to be pulled off in 10 seconds to check/repair stuff. This way, the airdam still comes off like usual - the whole brake ducting system is fixed behind it:
Cut el airdamo, and voila!:
