A step-by-step guide to installing a throttle pedal spacer in right-hand-drive vehicles. Covers fitment, adjustment, and common pitfalls for FK2, FK8, and GK5 models.

Quick answer

Install a throttle pedal spacer to bring the pedal closer to both you and the brake, making heel-toe shifting easier in right-hand-drive vehicles. The ACUITY spacer fits FK2, FK8, and GK5 models with three adjustable bolt patterns.

Why adjust the throttle pedal position?

In right-hand-drive (RHD) vehicles, the throttle pedal can feel too far from the driver or too far from the brake pedal. This makes heel-toe blipping awkward, especially during track driving. A throttle pedal spacer relocates the pedal closer to you and the brake, improving foot placement without modifying the pedal assembly.

What to check before you start

The ACUITY Throttle Pedal Spacer is designed for the RHD FK2, FK8, and GK5. It uses three unique bolt patterns for position adjustment. Confirm your vehicle is on the compatibility list before ordering. The spacer is full aluminum with Class 10.9 or higher hardware—no plastic parts to wear out.

Installation steps

1. Disconnect the battery negative terminal: Safety first. Disconnect the negative battery cable to prevent any electrical shorts or accidental starting while working near the pedal box. Do not skip this step even if you are only loosening bolts.
2. Remove the stock throttle pedal: Unbolt the existing throttle pedal from the pedal box. You will need a 10mm socket and possibly a small extension. Keep the bolts aside—they may be reused. Check that the pedal box area is clear of debris or aftermarket footrests that could interfere.
3. Choose your bolt pattern on the spacer: The ACUITY spacer has three sets of threaded holes. Hold the spacer against the pedal box and select the pattern that brings the pedal closest to your preferred position. Test the distance to the brake pedal with your foot. Start with the middle pattern; you can adjust later without removing the spacer completely.
4. Attach the spacer to the pedal box: Use the supplied Class 10.9 hardware to bolt the spacer to the pedal box. Torque to 8–10 ft-lb. Do not overtighten—aluminum threads can strip if over-torqued. Apply a drop of thread locker (medium strength) to prevent loosening from vibration.
5. Mount the throttle pedal to the spacer: Align the pedal with the spacer's holes and secure it with the original pedal bolts. Ensure the pedal moves freely through its full travel before tightening fully. If the pedal binds, loosen and re-check alignment—do not force it.
6. Reconnect battery and test pedal feel: Reconnect the negative battery terminal. Start the engine and press the throttle pedal through its range. Verify smooth operation and that the pedal does not rub against the brake pedal or console trim. Take a short test drive and adjust the bolt pattern if the pedal still feels too far or too close.
