Design back to the basics | 初心に戻ってデザインする

The angle of the Underwing, Max 15 degrease. Everything else is flat against the ground.

Normally, applying a setting like this in a racing car, the downforce would become too peaky and is likely to mess up the whole setting.
The reasoning to this is that making a steep angle will get better results on paper but………

For example, it will be like having a high HP engine that has high peak power but difficult to control and uncomfortable to drive….
thats is if…..if the car had a 600hp engine or something….
if we put in a peaky 200hp engine in a GTR, i bet nothing will happen.

But in race cars we calculate and assume the amount of downforce is close to the cars gross weight
we make adjustments and see the effects.

The same things can be said with tuning cars, we want to start with a mild characteristic
so we started out with installing a wing under the bumper…..

This picture is a part installed on a Stillway EVO
this was mainly for TSUKUBA, this part was dragged on the ground during the braking at the last corner.
The driver Mr Taguchi commented
“its not that peaky, but i would like more downforce.”

Next we installed a Spoiler on the Stillway EVO.
We had Mr, Yamada to test drive at TSUKUBA during an Interview he conducted. he also commented “Would like more Downforce.”
A little disgression, After the test Mr,Yamada introduced Mr Takizawa and Mr HRS to us.

Anyway here is the final design we came up with.

Performance wise its not that different but it looks alot better, So we started tests on the CyberEvo.
At this time i wasnt that interested in Super Laps but i remember getting a phone call from Mr Takizawa saying
“We got 55secs!!”

On the CyberEVO we were heading in the direction of using the Underwing as our main weapon.
as we moved on we face the strength problem of how to install the underwing failing at least 3 of them,
i remember thinking “whats going on??” making my first visit to Mr HRS.

A video showing the old CyberEVO was recently released
watching the CyberEVO running through the Autocrosses was memorable.

Since then our goal was to get 54secs at TSUKUBA, and our new challenge started.

“Maybe it was a little too much….this might make the car understeer or even oversteer during the last corner @TSUKUBA.”
I was worried untill Mr Takizawa said “Please try it!!” and here it is.

Even with this Underwing it was not peaky, it actually made the front tires less worn and was easily able to obtain 55secs.
We felt our goal 54secs was just around the corner.

Before this happend, maybe it was just me, who thought of seriously trying to run in 54secs,
understanding the difficulty that we faced with the old CyberEVO trying to make 55secs was infact a redeculous time
and i bet that everyone knew that.

This is our original, low cost/easily maintained and solved the instalation problems.

After making improvements to the hood and suspensions, this one made our goal of 54secs.

We still felt there were some improvements that could be made, and set our time to 53secs!!

And today This is our BABY running TSUKUBA.

After making the tread wider and wider, installing under panels to the front and middle
we were able to easily achieve 54 secs.


We are able to see the light of 53secs.
as of aero parts, we are not sure how much more we can make it lighter, were waiting for a chance…..

When we tried a SuperLap at FUJI, without making any adjustments to the CyberEVO specially tuned for TSUKUBA
couldnt even make a normal run there.

If we tried to maintain the height by installing different springs, we have to worry about  the strength of hubbearing and
parts that support around, if we do this it will make the car heavier which wouldnt be suitable when we go back to TSUKUBA.

If we manage to make a run, i cant image a good run due to the peakyness and the characteristics of the car.

We were able to reconfirm the importance and function of the crazy aeroparts
acting suitably @ TSUKUBA, creating the right amount of downforce, controlling the Cars gross weight
making the car controllable were normal cars would fail.

So what should we do now??

Heres the conclusion.

Create a dull underwing when speeds are over 200km(125mph)
it wouldnt work at TSUKUBA but use them at Faster Circuits.

Shapewise, Lift the front alittle bit and change the Underwing angle to 10~12 degrees.
a design used in Super GTs.

This design/conclusion coming from a long ways is pretty convincing.

The only problem now is if we can prepare all of this before the TEST on the 17th…..
We shall see…
