[This part is useful for improving the performance and settings of the machine]
A part with a sponge sheet attached is attached to the underside of the vehicle.
When changing lanes or going down a slope, the sponge comes into contact with the road surface to brake the machine and prevent it from going off the course.
Two heights can be selected, for small diameter tires and large diameter tires, and two types of sponge with different hardness are included.
The brake surface is made up of four interchangeable parts and two types of hexagonal shafts, allowing for a variety of settings.

Includes two types of sponge with different hardness
