NOTHING would get these to steer at speed.

This helped a lot but still not good enough.
Bought Rides and problem solved.

Wanna buy my Superions with the softer insert installed?
Like new!

Only about 10 minutes total run time on em, had to at least give em a chance to break in some before giving up on em.
