The rumbles can ONLY be removed on the builder while customizing your controller.

Feel the game with rumble packs built into your SCUF Impact controller. Rumbles vibrate and activate in-game based on how the game was designed. 

Why remove rumbles?
The vibration of a controller can throw off your aim in-game; this is why most competitive gamers have them removed.

• Removing the rumbles also gives you a lighter controller for added comfort during gameplay.
• Removing the rumbles will also disable the rumbles placed in the triggers of the controller.
