Odd Suspension problem...

Scratching my head on this one...

Left rear corner has dropped 25mm (32mm with the fuel topped off), added in a hefty amount of neg camber, cording a relatively new MPSS in less than 400 highway miles. Have not hit any potholes, debris, etc. Anyone seen something like this on their M5? Not looking forward to the dealer visit for this one.

Something major definitely is wrong and I've never seen anything like this on a non air suspension. Car was aligned not long ago and I definitely have not hit anything. No scuffs, bubbles, or bends and the front seems normal and in spec. Just doing a rough measurement myself:

Ride Height (ground to center of wheel arch - 1/2 tank of fuel)

Left Rear: 661mm
Right Rear: 686mm

Camber:

Left Rear: -3.12'
Right Rear: -1.41'

With the tank full, there isn't much travel remaining to the bump stop. Very surprised there aren't any chassis faults.

Has to be the alignment or a defective tire.

Yea it sucks donkey balls. My last set looked like that. Both sides. But it was due to bad alignment from BMW. Fucked off perfectly good tired. Had mine recently re alignment on a hunter machine. I also raised up my suspension a bit. So I'm hopi g not to ever see this again.

Here is mine, tire is still 7/32. Lowered and shitty alignment. Got it corrected, hopefully doesn't happen again.

I'm on DINAN suspension and they gave me the alignment specs to follow. The original installer didn't do it and gave me a bad alignment.

I just followed the DINAN spec sheet. Hoping that fixes it.

Can you recommend a good shop in the area that deals with lowered cars like ours?

Autoscope Plano did mine, they are also an authorized DINAN shop.

I checked my rears yesterday, so far so good.

Also another recommendation is European Auto Service in uptown off Tracy

Classic BMW in Plano did my lowering & alignment 6000 miles ago and my tires are in good shape so far. They are also a Dinan dealer.

Not my favorite shop ... they've f*cked up too many times on my M5. I guess it's hit or miss with dealers. I changed to BMW of Dallas. Great SA and the techs know their stuff.

Guaranteed to be hit or miss at a dealer and the tech. It's still unresolved until next week. I didn't discover it near home so it was a crap shoot to begin with using nearest dealer which is not close at all. No doubt the alignment is off by a huge amount as it should with the corner suddenly dropping so much with zero indications or fault codes, spring and damper appear fine, there isn't anything blatantly obvious with the links and arms, and absolutely nothing to keep an impact in the possibility. Rather get it to a better place and go through it with RSM, so best choice is get the tires on and have it aligned as much as it would go and run extra pressure to stop the sidewalk from compressing so much paid out of pocket

Still down too far and just under 3' neg camber and the only plausible thing left I can come up with for this particular combo is the mounting point on the body deforming.

And for the latest surprise...the 95mi drive back to leave the car until next week ended with the right front howling. It didn't leave that way.

I would be my guess that the toe angle on that wheel is way off, very positive toe. The wheel is probably trying to pull out sideways when you drive causing the suspension to squat. One test you can do is to back up straight for a car length or two and see if it sits right or higher than normal. And after a forward car length it squats again. This would confirm it.

I suspect Either they didn't lock the jam nut on the tie tod, or control arm if there isnt a tie rod, or they didn't align it correctly.


Another thing is if you've had the spring replaced recently maybe they forgot to install the rubber bushing at the top...
