Learn step-by-step how to install the PRIME Side Support Bracket on your sim racing cockpit, including common mistakes and tips for a rigid setup.
Quick Answer
To install the PRIME Side Support Bracket, gather your tools, align the bracket with your cockpit's side channels, and secure it with the provided hardware, checking alignment before fully tightening.
Why Side Support Brackets Matter
Side support brackets add rigidity to your sim racing cockpit, reducing flex during intense braking and cornering. This is especially important if you use a direct drive wheel base or load cell pedals, which generate higher forces.
The PRIME Side Support Bracket is built from the same high-quality aluminium as the Prime Cockpit, ensuring a sturdy attachment that integrates seamlessly with your rig.
Tools You'll Need
Before you start, make sure you have the right tools: a hex key set (metric), a torque wrench (optional but recommended), and a clean workspace. The bracket comes with all necessary hardware, so you won't need to buy extra bolts.
Check the included instruction manual for specific torque specifications, but a general guideline is to tighten to 15-20 Nm for aluminium profiles.
Common Installation Mistakes
One common mistake is not pre-aligning the bracket before tightening, which can cause misalignment and stress on the mounting points. Another is over-tightening, which can strip threads or damage the aluminium.
Always test the fit before applying full torque, and use a torque wrench if you have one to avoid over-tightening.
Installation Steps
- Prepare Your Workspace: Clear the area around your cockpit and gather the bracket, hardware, and tools. Ensure the cockpit is stable and not powered on if you have electronics attached. Check that you have all parts from the box before starting.
- Position the Bracket: Hold the PRIME Side Support Bracket against the side channel of your cockpit where you want to mount it. Align the holes with the pre-drilled slots on the profile. Use a level to ensure the bracket is perfectly vertical.
- Insert and Hand-Tighten Bolts: Insert the provided bolts and T-nuts into the channel, and hand-tighten them so the bracket stays in place but can still be adjusted. Do not fully tighten yet; you need room for alignment.
- Verify Alignment: Double-check that the bracket is aligned with your seat or wheel mount, and that it sits flush against the profile. Adjust if necessary. Misalignment here will cause stress and potential damage.
- Torque to Specification: Using a torque wrench, tighten the bolts to the recommended specification (typically 15-20 Nm for aluminium). Work in a criss-cross pattern if multiple bolts are used. Over-tightening can strip threads; under-tightening can cause movement.
- Test Rigidity: After installation, apply pressure to the bracket and check for any movement. If stable, your setup is ready for use. If you feel flex, re-check bolt tightness and alignment.
