I only have the in the fronts right now....but when time allows, I will put them on the rear of the bar also.
Had heims....then poly with no tell-tale difference...Finally the rubber.THEN, I noticed the difference.
I plan on making a complete separate set with rubber bushed on all four ends and put all heims back in the bars I have now for a trips to the strip. It is a lot easier to change the whole bar (one at a time) then swap the rubber for heims.
