My car is still riding rough?

Main issues:
- Car pulls both directions whenever the road is barely uneven, it jerks the wheel on bumps.
- Car vibrates at high speeds, >60 and gradually gets worse.
- When going over potholes or drain covers in the road, there is a knocking/clunk sound sort of as if you shocks kept hitting against something.

Things I have done to attempt to fix the issue: (fixed it all myself)
- New Enkei wheels 8.5/9.5 staggered and Sumotomo HRZ III tires
- New TRW M3 front upper and lower control arms
- New BMW tie rods
- New BMW upper shock mounts
- New BIlstein B4 front struts (this was last thing ive done, and car felt still rough, jerky and harsh after)
- Alignment done at both BMW and Firestone in a span of 3 months.

What could it be? I feel like my last options are either the wheel bearings and hub, the coil (whether the original coil is strong enough to be used with new Bilstein B4 struts) or whether I need to change the bump stops and all the other pieces that go along with struts instead of keeping the original ones?

Please I need this fixed!!

I assume you will not like my response but trading it in for something else would be the fastest and the cheapest fix.

If you decide to put up with the BMTROUBLEYOU check :
-are aftermarket wheels hub centric and properly balanced
-provide alignment print outs
-sway bar links
-U-joint on steering shaft

Have you changed the motor oil?

Oops, sorry, wrong thread!

1. I used to get that w/ stock run flats and stock suspension. 60% of it went away when I switched to non-run flats. 100% went away when I went to Bilstein B6s.

2. Since all your control arms are new, could be a bad tire, or high road force, or both.

3. As feuer mentioned, could be your endlinks clunking due to being worn out, or not tightened down enough, etc. Or an install issue related to other components; only someone that can put eyes on it that knows what to look for can tell you that.

I would upgrade shocks before changing out springs. The B4s are probably only valved slightly stiffer than stock; hardly enough to handle our big/heavy cars on soft OEM spring rates IMO.
