T-100 belly pan...

Had to do some maintenance on the diffuser so I figured I'd snap a piccie of the rubber support straps.


Four bolts/nuts and two pins and I can remove my diffuser with ease.

Those don't hold up to the UV in sunlight, but they should be Okay there.

I figured 9 straps would be better than 2 straps as it would allow more security in case the straps started to break.

Adjusted the rear crossbeam down another 3/4" to allow fer a continuous rise of the belly pan from nose to the end of the diffuser.

Here are the specs:
Truck length = 212" from nose to end of diffuser
Nose clearance = 7"
Rear axle clearance = 8"
Rear diffuser end clearance = 10.75"
Nose to rear axle length = 148"
Axle to diffuser end length = 64"
Belly pan angle from nose to diffuser end = 1.013 degrees
Belly pan angle from nose to rear axle = 0.387 degrees
Diffuser exit angle (rear axle to diffuser end) = 2.46 degrees

The word "comprehensive" comes to mind.

Fantastic looking.

Sorry if I missed it, but what is up with the strips of fabric looking material hanging down near the end?

Is that the "rear diffuser" mentioned in an earlier post?

The beat up Coroplast is what I think you are referring to are my rear skirts. They started out long ago as square pieces that the road eventually shaped to the maximum drop I can have back there. I'm not sure if I want to convert those over to metal or not (maybe in conveyor belt material) but it does give me a good framework to build out some detachable flexible rear strakes. I have noticed that the front part of the rear skirts are being drawn into the rear tires and making contact at speed. It ends up funneling the air into the rear difuser.

This is when I first installed them back in 2010.

The adjustable rear difuser is the sheet of diamond plate closest to the camera. I can adjust the exit angle with the rear brackets.

Old picture from link provided:


Blows my mind that the existing little strips once started out as much larger flange strakes.

Good thing you didn't do them out of aluminum, the noise of them scraping up and down driveways would have been intolerable.

There are these front skid plates they make for the front of a Porsche 911, they sound like hell when they make contact.

Most of the rear skirt wear has been on the entrance and exits of driveways and ramps. There have been times where it crushed the skirts when I would back up into one of the parking curbs.

I've been talks with aerohead to maybe make an adjustable/motorized platform that you could raise at slow speeds and lower during cruising speeds. It might be possible to adapt an old window motor/mechanism and some creative engineering to perform this task. I would make a U frame and attach the extensions to the current side skirts with the pivot point near the rear axle. This isn't a high priority project at the moment but it will reside on the back burner fer the moment.
