Bilstien Sports and M5 Thrust Arm Bushies installed

[Jehu]

My fears over these being too stiff are gone. They are perfect,I love them. But even after;New Tie Rods,new Lemforder M5 upper control arm/ Thrust arm bushings,new hub-centric rings all around one wheel trued and balanced on the right rear and two front wheels balanced i can still ever so slightly detect around 55 MPH an occasional steering wheel connected wobble.Only at certain times but i really feel it and i don't believe i should. can the Lower C/A's allow for this? What else up front need i inspect and or replace? Sway bar bushings? Sway bar links? Lower control arms? what else is there? Rotors aren't even a year old (Brembo slotted with Akebono proAct pads still with plenty of meat) The shop who did the suspension had to apply weights to the outer lip on my Rondell 58's to get them to balance... its an abomination to say the least but i thanked him for actually getting them balanced. I suggested if they needed that then they must be bent and he said they weren't( he did balance them ,i guess he'd have seen if they were) anyway like i say maybe I'm being extreme and failing to distinguish road ripples from wheel wobble but i am pretty sure i can still sometimes detect it slightly.. maybe his balance job wasn't as good as he believed. Should i try it on a Road-force balancer? can they reveal anything beyond wheel balance?
