Go Big or Go Home..
The one modification with questionable aero results has to be the Carbon Rear wing I added to my IQ.
This is actually the second wing I have had on the IQ, the latter being Aluminum, the new one is all Carbon Fiber.
The new wing has been modified to fit with new brackets, here is how I did it..
The old Aluminum wing
Here is the one I had originally installed and ran for a year or so, complete with custom brackets, It actually looked pretty good and withstood some 20.000+ miles of road use.
Compared to the new one it actually looks pretty small. I sold it to a nice guy who installed it on his IQ for Autocross racing.
Fabricating the mounting brackets
Using some 1/2" aluminum plate I used a couple of cardboard templates to get the correct angle and roof contour before cutting them out on the bandsaw. Once they were to size I cleaned them up on the belt sander.
Finished brackets
The 1/2" wide brackets are secured through the top of the rear hatch using a single stainless M8 Allen bolt. The 8 X M4 holes are for the wing angle adjustment
Drilling the rear hatch
Using the existing mounting holes I already had for the old wing I opened the holes up to take the larger M8 Allen head bolts.
Mounting the brackets
Using a single M8 stainless Allen bolt to secure the brackets in place.
A little too wide for the IQ
The new carbon wing looked too wide for the IQ, at 60" it was meant to go on a much larger sports car. So I cut 4" off each side.
Now it looks better..
I cut the wing down on each side to a more sensible and aesthetically pleasing size.
With this modification It is now 52" wide.
Accessing the inside of the wing
Another advantage of cutting down the wing was to gain access to the inside. Because the mounting holes do not line up with my old wing holes I had to make some new ones.
Adding some strength
New holes were drilled in the wing to match and line up with the ones already drilled out in the rear hatch.I bonded a curved threaded plate to the inside of the wing and then filled it up with polyurethane foam. The end plate fixing brackets were also bonded into place for the side plates.
Bolted in place
Using stainless Allen bolts the wing is bolted onto the bracket and secured in place. The angle can be adjusted but for now it seems to drive really nice and has no effect on drag that I notice. If you look closely you can see the reverse lettering in the reflection of the rear window "powered By YAMAHA" that I added.
Adding the Graphics
I decided to add a bold "TOYOTA " graphic to the rear of the wing, using my vinyl cutter software I created an exact copy of the logo that was cut to the wings contour and dimensions. No pun intended, But I kind of winged it..
Carbon side plates
I cut the carbon side plates to a much better shape than they were originally. Using stainless screws they bolt up to the aluminum plated I bonded inside the wing. The "Powered by YAMAHA" metal decal finishes it off.
Applying the decal
I made a couple of different sized decals and opted for the largest one after a bit of trial and error. I may change the color in the future to Red if I get the IQ painted another color. Having a good software programe makes it easy to scale and curve the decal to fit the wing contour.
Rear wing install completed..
The sound and stance of my IQ demanded an aggressive rear wing of some size and stature. I wanted the car to have something to say, adding this large wing is just what it needed.
First reaction from people who see it is a smile and a little laughter, but once they walk around the car a couple times the criticism changes to positive and nearly all say they love it.
Love it or hate it it`s staying... unless someone has a genuine WRC rally cross wing they would like to sell me... and then I will change my mind..
Now on to the next task..
