FAQs
What is the main benefit of using this steering wheel spacer?
The primary benefit is the ability to adjust the steering wheel's position closer to or further from the driver, allowing for a more ergonomic and comfortable driving posture, which can enhance control.
Will this spacer fit my Momo steering wheel and my specific boss kit?
The 120mm spacer is multi-drilled for both 6 x 70mm PCD (common for Momo, Sparco, OMP) and 6 x 74mm PCD (common for Nardi, Personal) steering wheels and bosses. Check your specific boss kit's PCD to confirm compatibility.
Does this spacer come with all the necessary hardware?
Yes, the B-G Racing alloy steering wheel spacers include the required bolts and a wrench to fasten the spacer to a boss kit and the steering wheel.
Can I use this spacer with a steering wheel that has an airbag?
This product is intended for aftermarket steering wheels. If your vehicle has an airbag steering wheel, it must be replaced with a compatible aftermarket wheel, and proper procedures must be followed for airbag system safety.
How thick is this particular spacer model?
This specific model is the 120mm thick version.
What is PCD and why is it important?
PCD stands for Pitch Circle Diameter, which is the diameter of the circle on which the bolt holes are arranged. It's crucial for ensuring the steering wheel and boss kit mount correctly to the spacer.
Are there any restrictions on PCD compatibility for this spacer?
Yes, while the 120mm spacer is multi-drilled for both 6x70mm and 6x74mm PCD, the 10mm and 20mm versions specifically require the boss and wheel to have the same PCD. Ensure compatibility for your chosen spacer length.
Troubleshooting
Steering wheel does not align properly with spacer holes.
Verify that both the steering wheel and the boss kit have compatible PCD measurements for the spacer being used. Ensure you are using the correct spacer length for the desired compatibility.
Bolts do not seem to fit securely.
Confirm you are using the correct bolts provided with the spacer kit for attaching it to the boss kit and the steering wheel. Ensure threads are not stripped.
Spacer rattles after installation.
Re-check and tighten all bolts securing the spacer to the boss kit and the steering wheel. Ensure the spacer is seated flush against the boss kit.
