Does this help reduce slop in the steering? on my granite 3s blx its hard to drive in a straight line on the pavement which is a common complaint.

Yes the hot racing steering rack reduces most of the slop

I installed this on my arrma big rock and i have a lot of slop in the saver! is there an adjustment for the saver??

nope. Mine broke the second time I used it.

Will this fit the 1/10 Arrma Senton 3s?
