94 VX 1000 mile tank @ 80 MPG

[The donkey CRX]

Thanks, I'm not sure which one it is, my brother got it on E-bay for about $30. It added about one inch to the bottom of the front bumper and was the exact size we needed to bring the belly pan up to the bumper and keep it flat. This made a much more finished look up front.

Here is the front end of the belly pan before it meets the spoiler lip.




Here are the three pieces of the front belly pan with the black spoiler attached.





This is the material we made the belly pan from. It is 1/8 inch polycarbonate with a thin layer of aluminum on each side. It is very easy to work with and can be cut with a jig saw and edges sanded smooth. It cost about $50 per 4X8 foot sheet. We got it at Piedmont Plastics in Memphis. It took 2 sheets to do the complete 3/4 belly pan front and back on this car.

How are you attaching the belly pan to the car? Using existing holes? drilling into the chassis? creating custom brackets?

Hi Jedi, The frame work for the belly pan is made of 1/8 inch by 2 inch aluminum. It is attached on the sides between the wheels to a 1/8 thick 1"X1" square rod that is screwed into the bottom of the rocker panels.

Across the car the 2 inch aluminum is screwed into the "frame rails" with self drilling 1/4x20 stainless steel screws. They are also attached by 4 1/4x20 bolts installed through the floor pans 2 in front and 2 behind the front seats.

The side skirts between the wheels are also attached to the outside of the 1x1 square tubing.

I could only find one picture of the frame on the white VX, but included some from the red VX which was installed the same except because the white VX is lowered 2 inches, the belly pan is tucked right up to the frame rails.

Thanks for your input! Since my car is newer, I am trying to avoid drilling into the chassis of the car.

However, your use of aluminum tubing on the sides of the car has given me a new idea on how to make my underbelly pan sit more flat/even.

Looks awesome! Great work, as always, and this one is very sleek!

Your driving is phenomenal. That is obvious. Unfortunately, we can't see that in the pics, ha!

Hi The donkey CRX,

Do you happen to have the dimensions of the belly pan?

[The donkey CRX]

Thanks OG, you are our inspiration to try and make something sleek but also functional MPG wise.

I really like the way yours is progressing. I thought long and hard about doing the curved radii behind the front wheels, but never got the nerve to pull the trigger. You are fearless

Thanks for sharing your journey with all of us here at Ecomodder!

Hi Derp, If I remember correctly the width of the belly pan between the wheels is about 57 inches, but this number is dependent on where you put the frame for the sides and the side skirts.

The white car has a more narrow belly pan width because we left the black rubber trim on the sides and came in 2 inches from the edge in order to help hide the skirts.

On the red VX the belly pan is more like 61 inches wide because we came out to the full width even with the doors to install the skirts. This is much more aerodynamic, but not as appealing to the eye.

The widest part of the belly pan is on the nose right in front of the front wheel openings, about another 2 inches wider on each side.

Hope that helps

That does help out, I will be attempting to make that belly pan.

Thank you

Here are some pictures of the rear belly pan with attached diffuser.

The diffuser was designed for a Honda S2000 and was bought some years ago to be put on a Mazda Miata. We had to make it quite a bit smaller in order to get the front part to be parallel to the ground. The transition to the back is curved and probably not too close to the template. But maybe it will get some style points.
