3D model description

Front-Splitter for the Traxxas Fiesta ST Rally.

Fits on 220x220mm build-plate at a 45degree angle

On high speed runs, or tight cornering, your RC car needs more downforce to stay on the ground. This Front-Splitter directs oncoming air up, and creates a vacuum under the car, keeping it sucked to the ground.

The front of the splitter follows the lines of the bumper to keep it looking sharp.

This specific, on-road version of the bumper is made for speed_runs/Drag/Circuit Driving only, because the splitter will not allow the front A-arms to travel below parallel to the ground.

It is REQUIRED to lower your Traxxas Fiesta. with the A-arms
parallel or facing upwards.(as shown in photos)

If you are wondering how to lower your Traxxas, here's a how-to: https://youtu.be/uytvBXu4xKE

To Install on your car, simply uninstall the front-skid plate with the 3 screws on the bottom, and the 2 holding down the foam bumper. (as shown in the photos) Then install the Front splitter where the skid-plate was, with the screws that held it in.

Note: When threading screws into the plastic, I recommend to heat up screws with a lighter to thread.
