PEDAL THROTTLE SILVER – WP25003

PEDAL THROTTLE SILVER – WP25003

Functional Overview

The WP throttle pedal assembly replaces the factory steel  accelerator pedal used in right‑hand‑drive vehicles. It is engineered to maintain the original pedal ratio, hinge geometry, and cable/position‑sensor alignment so that throttle response and calibration remain unchanged. The pedal operates as a lever arm mounted on a pivot bush, transmitting driver input to the throttle cable or electronic sensor.

Construction and Materials

• Main pedal arm: CNC‑machined aluminium, anodised in silver to increase corrosion resistance and surface hardness.
• Pedal pad: Aluminium, left unanodised to prevent visible wear marks from repeated foot contact. Bare aluminium develops a natural patina rather than showing patchy abrasion.
• Mounting hardware: Typically stainless steel fasteners to prevent galvanic corrosion with the aluminium body.
• Pivot interface: Designed to reuse the OEM pivot pin or bush, ensuring correct pedal travel and smooth operation.

Mechanical Design Features

• Right‑hand‑drive geometry: The arm is shaped align with the driver’s natural foot angle.
• Lightweight construction: Aluminium reduces mass compared to steel, improving pedal return speed and reducing fatigue on the return spring.
• Drilled pedal pad: Multiple holes reduce weight and provide grip. These holes also offer convenient anchor points for the return spring used on later MPI models.
• Compatibility with OEM return spring:
  • All models from 1959 including MPI (1996‑onwards) vehicles which use a lower‑arm return spring.
  • Many users attach this spring through one of the drilled holes in the pedal pad, which provides a secure and functional mounting point without modification.

Integration With Brake and Clutch Pads – WP25005

The throttle pedal is designed to visually and ergonomically complement matching aluminium brake and clutch pedal pads. When combined:

• Pedal spacing and height remain OEM‑correct.
• The driver benefits from a consistent metal‑pedal surface across all three controls.
• Aesthetic uniformity is improved, especially in motorsport‑style interiors.

Installation and Compatibility Notes

• Direct bolt‑on fit for right‑hand‑drive models using the standard pedal box.
• Compatible with both cable‑operated and early electronic throttle systems, provided the original linkage or sensor mount is retained.
• No modification to the bulkhead, pedal box, or throttle cable required.
• For MPI models, the return spring can be relocated to a drilled hole without affecting pedal travel or spring tension.
