speed coil 

The speed coil is a very well known Roblox item, very useful to be faster than a normal player without a speed coil. If you manage to get one Irl, then you can try to be fast as much as you want.

You: ayo this speed coil game pass is too expensive...
Chad: do you really need a speed coil to win?
