Partial rear wheel skirts/deflectors?

[BamZipPow]

Had a little bit of time and scrap Coroplast to work with so I slapped these on prior to my trip... Not pretty...but it's just fer fun.


Any data on partial wheel skirts? I know my data will not reflect separate data just on these as my upcoming trip will be the first long distance trip with my revised aero cap, revised engine belly pan, extended rear diffuser, and now the partial wheel skirts.

Aerohead would better watch his mirrors

It sure looks like you're doing some serious catching up on the aerodynamics front

This is NOT your exact configuration, but it does show benefit :



When they were making the GM EV-1 they chose partial wheel skirts :



They could have extended the skirt down more, but they were happy with the compromise.

If you look at rear view in this picture you can see that you *could* extend the EV-1 wheel skirt down even more :



When I say this I am assuming that the suspension doesn't make the rear wheels bow too much into negative camber when the car bottoms out :

Started framing out my rear wheel skirts today. Now you know why I had those PVC pipes in the rear fer...

Some basic framework...


Trying to git the proper clearance...removed the chrome trims.






Since playing with a partial rear wheel skirts about a year ago, I know I want to pivot the rear wheel skirts where the top of the side molding starts (hence the top wire divider). The rear wheel skirts will have their own support bracket that isn't attached to the side skirts as the frame flexes and would affect the rear wheel skirts if they were attached. This will also allow me to easily access the rear tire fer rotation or repair.

Thinking about making a quick paper mache pattern to make sure I have the proper clearance from the tires. The bottom of the wheel skirts will match up with the side and rear skirts. Thinking about using some more Coroplast or leftover FRP as my test material. We'll see how things turn out.

Quick fab...

Thinking a little differently. Was trying to reinforce the wheel skirt from the inside...why not the outside instead? Had some ½"CPVC (pex tube/pipe) around so I decided to use it as my hinge and exterior support. I will paint after I git it fabbed up.

The white stuff around the wheel well is a plastic corner bead fer archways. Costs about $3.

Mock up of the hinge/support bar...


Rough fit...


Gitting there...

Quick paint job...


Still have to zip tie it in place and then secure the top edge with either zip ties or screws.

The bottom portion of the wheel skirt will be reinforced on the outside with pex pipe as well. It will be zip tied in place so it will be easy to remove as needed.

Quick setup...


Still have to button it some more and then do the right side...
