Finished a trip this past week up to my parent's cottage. About 1800km total going there/back and driving around.
So I think the steering wheel moving over bumps at low speed is not really an issue. I might have only noticed it since I had changed all the suspension components and it is a bit stiffer now, it feels good after putting some km on it. I have a small clunking noise when moving slowly and turning the wheel slightly, comes from the passenger side. Either end links (as I installed my old ones) or maybe I screwed up the strut bearing. I will take a look tomorrow.
Happy to say no issues the whole trip, car was awesome on the many large hills. Rear shocks seemed good even with a lot of junk in the trunk and two dogs, I still have them set to what MNIWT had suggested in his video. Front is still set to 1/2 turn away from the softest setting, I am happy with it.
Right before I left I notice my steering wheel had a vibration at ~100km/hr. Hadn't really driven that fast since the alignment etc. I had the wheels balanced a few hours before we left and it was great. The only vibration was during braking at about 120km/hr down a steep hill (cars in front were braking, otherwise I would have just coasted). I guess rotors may be slightly warped which I hear is common. I don't think it is much of an issue yet, and I know the place I bought the car from likely installed the cheapest pads/rotors they could find.
Borrowed a friend's thule cargo box as well for more space (really wishing for a V70 or something now but prices seem crazy).
I used to feel that butt push back when accelerating hard in 3rd gear, it seems to be wearing off and I and I am just getting more used to it. I think Stage 1 tune might be in order.
The only other minor issue that might be related to the cargo box is that the sat radio kept cutting out.
