What are the material and manufacturing highlights of GPM EF021?

GPM EF021 features precision aluminium construction emphasising strength and wear resistance to improve steering stability over time.

How do these knuckles affect steering setup and tuning?

Upgrading to aluminium knuckles reduces component flex, which can affect steering feedback; you may need minor adjustments to toe or camber to optimise handling for racing or high performance use.

Are there special fitting considerations for track use?

Verify all mounting hardware is torqued correctly and inspect parts after heavy sessions. For competitive setups, pair with high quality servos and hardened linkages to get the best steering precision.
