I've just fitted reaction bars and also a panhard rod to my 2014 Plus 4. Due Cornish weather, only taken a short test drive so far but does not feel much different. Hoping to take a much longer (more energetic) drive today. One small problem I encountered fitting the reaction bars was difficulty screwing the top oiler bolts back into the suspension uprights. Had to loosen the small bolts at the bottom of the upright and then tap the spring in various directions to re-centralise the kingpin before the oiler bolts would line up and screw back in.
2014 could well have dome top kingpins and they do 'float' a little when the top bolt comes out as the camber plates put some load on them, not always fun to re-align. Your spot on with how you achieved this, I have a tapered pilot tool for assembly and even with that its a delicate job to get the top bolts back in.
