I've been having a steering problem since a first ran the E4JS. At first, I thougt it was suspension slop from the plastic componeents. I replaced all the plastic arm holders and hubs to aluminum and shimmed out any slop. I still have the problem of the steering not centering right.

I then thought it may be the servo but it is a KO low profile PDS-2413 which I doubt would have a centering problem. So it boils down to the servo saver. I tightened it as much as I can and it still gives me problems with inprecise centering and steering.
Would the K Factory aluminum single arm steering kit fix this problem? Is it possible to put a tighter more precise spring in the servo saver? Can I just eleminate the servo saver spring and have it as direct steering?
