Description
Please note that using a belt drive first stage in place of gears will reverse the rotation of your wheels. You must either swap gears in your transmission or reprogram your ESC to correct this

These are pulleys for converting your RC drift car to have a belt drive first-stage. The pulley profiles are HTD 3mm but I recommend using them with S3M belts for less friction. I have tested it and there is no noticeable difference in how the profiles print.
A 50T belt is a good starting point for 15T/40T on the pulleys.
Pinion Notes:
The pinion is configurable from 14-20T and is meant to press onto a 14T/48P Pinion gear. Please print true to size for best performance.
Spur Notes:
The spur is configurable from 36-48T and has an 8x16mm bolt circle to fit most drift chassis.
Again, print true to size for best performance.
