JAI-R07D Downforce IV

Auto Credit Based on Jukkelus's JAI-R07B Downforce II

The ultimate version of the Downforce is my failed attempt to complete each race under 20 seconds.

Max speed is 570+ mph. Acceleration to max speed under 2 seconds. Can complete Gold Prix in 22 seconds and lap the Skidmark two times while it completes it's lap. Airstrip drag in 24 seconds. My reaction time is too slow to manage even one lap in Motor Mirage so no time from there, sorry.

Controls: Pitch is Throttle, Roll is Steering.

    @AWESOMENESS360 Yep

    This is the 5. version shared and 9. saved in my editor. And that number doesn't include prototype versions before the 1. shared version.

    Hopefully my previous post gave some useful tips in building fast and manouverable cars.

    @Jukkelus huh, I guess it took a while to make, didn't it?

    @AWESOMENESS360 Wow! Thanks for your comment, upvote and highlight!

    The speed and acceleration come from xml modded engine power, wheel angular speed and longitudal grip.

    Lots of downforce from wings prevents unwanted take-offs and makes manouvering possible.

    Finally xml modded wheel lateral grip. Rear wheels must have more lateral grip than forward wheels to prevent spins. If fore wheels have too little lateral grip, the car won't turn and if too much the car turns too fast. I found the right amount by trial and error. Adding more wing helps cornering.

    Finally I found out that it's better to have moderate steering angles on all wheels than large steering angles on front wheels only.

    How do you even make a car this fast, while still being capable of extremely tight turns?! It's crazy, and I love it!
