So I recently bought a left and right handed Gladiator EVO 'SCG' Premium and they're great so far.

I've noticed an issue however: on the right stick when moving it all the way right and letting go it centers roughly twice as fast as when I move it left. The left stick doesn't have this problem.
Is there something I can do to fix this? It's not a huge deal but still.

Fully release the dry clutch on that axis and check again.

After fully releasing the clutch both sides center at the same speed (or at least not noticeably different), but when tightened down again the right is still noticeably faster to center

Then I would say it's normal behavior if this happens only if the grip is released because during normal use your hand holds the joystick.
