Which rear arms are confirmed to work with this extension?

Does the aluminium extension need threadlocker?

Using a light threadlocker on steel screws that mate to aluminium is recommended to prevent loosening during racing, but avoid heavy compounds that make future servicing difficult.

How do I check alignment after fitting?

After installation, check that the shock mounts and pivot pins sit flush and that there is no binding through the suspension travel. A quick run-in and visual check will confirm correct alignment.

Can this part be used for everyday practice sessions?

Yes, it is suitable for regular practice and race use. The aluminium construction helps maintain geometry under repeated loads commonly experienced in practice sessions.
