Extension Keys expertly adjust pedal height to perfectly match your foot size and driving style, transforming your simracing posture with superior ergonomics, comfort, and control.
This essential upgrade delivers a natural, efficient driving position that eliminates fatigue and maximizes precision during intense racing sessions.
Extension Keys shine for drivers with larger shoe sizes (EU 44 / US 10 / UK 9.5+), raising the pedal surface to eliminate excessive ankle flexion and perfect heel-toe technique.
Drivers with smaller feet also benefit – easily lower pedal height for optimal comfort and precise control tailored to your build.
*Note: Sized for racing shoes – casual footwear may vary slightly.
Available for 2- and 3-pedal configurations, these keys adapt any SRP pedal set without sacrificing aesthetics or performance.
Engineered to deliver clean, professional integration every time, maintaining the premium look of your simulator cockpit.

A mobile-ready comparison of how SRP® dynamic air physics positions itself against traditional SimRacing technologies.
Rubber compression (Static resistance)
Linear & dead. Often described as "wooden".
High. Elastomers degrade and soften with heat/use.
Air dynamics do not fatigue. SRP maintains a perfect, temperature-independent feel for years.
Oil displacement (Organic feel)
Excellent initial bite and realistic pressure curve.
High risk of leaks. Requires messy fluid changes.
Zero mess. SRP replicates fluid physics using compressed air and industrial seals (No oil leaks, ever).
Electric Servomotor (Fully software driven)
Infinite customization, but can feel synthetic or artificial.
Extremely complex electronics and high software reliance.
Natural, organic physics at 1/3 of the cost. Mechanical tuning is intuitive and tool-free.
Dynamic Compressed Air (Industrial grade pistons)
Authentic exponential curve. Replicates a real master cylinder perfectly.
Zero. Rated for 3.5M kilometers. Industrial NBR Seals.
