Hardware – Sim Pedals Ultimate – Adjustable Pedal Travel Options.

Niels Heusinkveld uploaded a video showcasing various options to adjust the pedal travel and brake pedal strength of the HE Sim Pedals Ultimate.
As stated by Niels the pedals are installed in a temporary cockpit made of MDF which is not really rigid enough to accommodate the high pressure loads on the pedals.

Heusinkveld Sim Pedals Ultimate are suitable for high-end professional motorsport simulators. A strong, stiff, compact and durable design using custom developed 12bit USB electronics for an instant and accurate response. 

Maximum brake force is 136kg (300lbs), maximum clutch force is 45kg (100lbs). Fully adjustable pedal geometry and pedal force. These pedals are capable of simulating the pedal forces as experienced in F1 and LMP-cars.
