Moza SR-P Lite Brake / Accel mod

Use a 5mm rod with 8-9mm in length, glued to "rod_start" and screw it into the pedal existing holes, double check length before cutting so it doesn't hit the bottom of pedal base. Use screws on "rod_end" with heated inserts or bigger screws then mount it to the existing locking mechanism in the pedal base. Use a 20mm (outer diameter) spring between "rod_start" and "rod_end", passing the rod in middle of it, it will be secured in place by the 2 ends then attach to the base.

Depending on print lines you may be able to feel it because of the rod rubbing in "rod_end" print but can be sanded a bit or even also lube it.
