A neverending battle trying to make my E46 handle well.

I have new control arms, shocks, springs (H&R), LCAB bushes (poly), RTAB (poly), anti-swaybar & bushes (from M3), shock mounts, brakes, tyres, and I've had an allignment 3 days ago. The rear subframe has been welded where it normally tears.

Still my car feels completely out of control in a straight line, especially with wind very hard to keep straight .. honestly don't understand what it can be anymore .. replaced basically everything.

What tires did you put on? what pressure are they at?

Michelin Pilot Sport 4, stock sizes, (255x35x18) and (225x40x18) on Style 32 rims. I have tried them at 2.5bar and 2.8bar, pressure don't seem to make much difference

I have same issue with my stock X6 E70 40d, replaced everything- stock suspension, Bilstein B8s (for standard suspension height), kilen oem springs. It has servatronic steering.
It’s either the case of height somehow changed so I need to alter my tie rods height (willing to raise my steering rack to test this), could be servotronic torque converter (replaced woth second hand one, but never know) or steering pump. Also steering feels to light.
I have a feeling steering pump is ‘overboosting’, or somehow allowing fluid to return instead of blocking it when it should allowing steering shaft to travel. Probably some valve stuck open or something. I can’t see any other logical reason.
