WTF Was I Thinking?
Lawn edging? Really? What in the actual fuck posessed me to use ugly ass LAWN EDGING for the splitter air damn? I mean, look at it! Did a pack of monkies do this?
Lawn edging delete. Replaced with 2" aluminum angle.
Frigging perfect. Ok, NOW I can move on to the dive planes and end plates.

Rob had a good idea. The current version is fine for concept testing but ultimately we'd like a quick change splitter. Remove the two bumper bolts and pull the whole thing, bumper and all. I can do that using this complete aero front end and building an aluminum support frame inside it. That will be v2, once the new shop gets built. (Soon)

Adjustable splitter supports. Whole thing is very sturdy. Valence next

More fab. Simpler is better. I eliminated the height adjustment. Just using a straight mount to the splitter.
u-channel for the mounting point
Carriage bolts with washers to spread the load
After lots of bolting it on, measuring, taking it off, repeat. Coming together.
Mounts are really solid. Pivots to adjust the angle
Perfect fit
Now I have to design the rest of the mounting points, so down angle on the splitter doesn't become up angle and start generating lift. This will be harder as there is more crawling around under the car involved.
To be continued ...

Adjustable height splitter frame mount.
U-Channel gets here from Dallas tomorrow so I can finish off the pivoting splitter attachment.

New shape looks good
Tunnels fit
Frame mounts are good & strong
Pro tip. Level the car with driver weight in seat. #facepalm
Contemplating the mounting frame. I have lots of aluminum drop to work with

Looking better. I like it. Will use this to study if I can make the tunnels bigger. Next time ....

Here are the tunnels, $150 for the plastic regular size:

These links are pretty good. Suggestions for splitter length follow each:
NASA 4" -6"
Professional Awesome 4" - 8"
GRM 4" - 6"
MOTOIQ ~4"
Introduction to Aero 4" - 8"
G-Stream < 3"
So? As DigitalWave noted I have WAY too much splitter Probably only need ~4" to balance the 500 lb wing.
Will get out the saws-all next time.

I started larger so we can cut it down as required. Might end up smaller. I'm still researching.
Professional Awesome distributes Racebred splitters. They look fairly decorative. No tunnels or front supports from what I found. Anyway, I like building things : - )

Is the outer profile just roughed out for now or is it really going to be that large? It looks much too large for the wing you're running.
Professional Awesome makes some preformed plastic splitter tunnels if you want to save some effort, they are relatively inexpensive.
