First things first. I'm not claiming this piece to be beneficial to the aerodynamics of my car. I'm not saying it provides down force because frankly I don't know if it does or not. Hell, maybe it even has negative effects. Frankly I don't care because I couldn't tell a difference either way. I made this diffuser as a visual modification because I've always been a fan of track spec looking cars. So if it is beneficial to the aero of the car then great and if it's not beneficial to the aero of the car then that's great too. With that being said lets get on to the pictures and info!
There has been about 5 variations of this diffuser that I ended up making and finally I came up with a design that I thought was the best looking. I only took pictures of 3 of the set ups so that's all I have to show you guys but the other 2 set ups were just small variations of the main set ups.
Picture number 1
This is the first design I came up with. I quickly got bored with it and decided to add more fins.
Picture number 2
This is the second design I came up with. It is similar to the first one but has more fins.
Picture number 3
This is the final design I came up with. It is my final and favorite design I decided to stick with. I took all of the added fins from design 2 out and replaced the 4 vertical fins with thicker 1/4 inch abs plastic fins. I then added 2 horizontal pieces in between the vertical fins. Next I added shorter, smaller fins on the end of the diffuser. Then, finally I added large 1/4 inch abs plastic fins on the outer edge of the bumper to complete the look.
The base plate and horizontal plates are made of 1/16 sign material. This material consists of a piece of abs plastic sandwiched in between 2 pieces of 1/32 aluminum. Total thickness of this material is 1/16 inch. The 4 main vertical fins and the fins on the end of the diffuser and edge of the bumper are made of 1/4 inch abs plastic.
I will eventually make the entire thing out of 1/4 inch abs plastic because I like the look of the thicker material.
Here are some more detailed pics of the diffuser showing what the fins, brackets and everything looks like up close. I apologize, my car is very dirty as it just rained here in California today.
