I replaced both front brake discs and set of pads to my E90 325i, calipers were in good nick so only slight lubrication to brackets

What are the alignment settings?
The steering shouldn't feel overly light, but there's always a very slight dead spot straight ahead... This is a normal side effect of a steering box when compared to a rack, but weird is never a positive description.
Whilst still shit, one brand of cheap tyres will perform unpredictably under certain conditions when compared to another.
If everything is playing free at the back and you haven't changed anything then I don't see how it can be an alignment issue
To properly check the diff/rear subframe mounts, support but DO NOT lift the diff with a jack. Then undo one of the mount carriers. If the frame falls off, then the mount is done. Refit and repeat the other side.
You won't get any noise when these fail, but it will allow the weight at the back of the car to move in ways that you can't predict.
You need better tyres.
The omega isn't particularly tail happy as a rule.
I've lost the rear of a Vectra C estate more times than any rwd car I have owned. Even the S500 which currently has no ABS/Traction Control.
It's one thing to chirp they tyres pulling out of a junction expeditiously
But if you're trying to slide it at every opportunity, then you'll eventually run out of talent. With luck you'll only damage your ego and the car...
I wouldn't consider any of those tyres to be good.
