You are always going to have slop no m,atter what you do......it's just the way it is designed! The E steering is way better than the standard one by far.
The main culprit, once you have all the steering upgrades, is the play in the front suspension and steering knuckles due to the way they attach to the suspension arms!
The ali steering arms are only slightly better than the standard type E steering with bearings and not really worth spending all the money on....unless you want the bling
