The SIMSONN Plus X pedal is the ultimate upgrade of the Pro Plus pedal. It comprehensively enhances pedal structure and quality, upgrading the brake pedal resistance system, hydraulic system, control box, and software, while adding the Rumble Module. The braking mechanism has been improved with shorter spring travel to simulate real brake pad feedback. The elastomer materials have been significantly upgraded, with each type tested through tens of thousands of compressions to ensure absolute strength and durability. The software has also been upgraded to support the new Rumble Module, delivering the most realistic driving experience.
