Default D'uuuuhhhh Dis How Rear *Shock* Towers Look Factory, Right?

Ripped my carpet out a smidge as part of my "coilover" install (that I never finished because my front sway bar end link was impossible to get detached from my strut) and was kind of puzzled by how the paint looks around it so I thought I might share and ask if it's normal.

I'm guessing it's all normal, as it appears to be holding the struts fine, but just wanted to be called a noooob on here before I'm 100%.

Very surprised my struts weren't shot through the tower or anything as I've heard a clunking for a short bit from the RR side.
Now onto figuring out if it's the blown strut, something with my RTA's, or something else!

PS: what looks like rust in the second photo isn't, it's the carpet being pulled back. The lighting in the photo makes it look like some weird rust hole, or at least to me it does so I went back out and checked.

paint overspray looks factory to me. seam sealer too. bmw saved money on paint by only putting exterior finish paint where necessary. trunks/enginebays/undersides have crap paint coverage + other cost savings


remove swaybar up front and replace links, their cheap. removing sway links requires holding the ball joint from spinning while removing the nut. believe its a 15 or 17mm wrench required on the back side.


get reinforcement plates

The towers look fine but you need to clean the filth off to know for sure.

The driver side shock mount washer is installed upsidedown. It is not supposed to cup the bushing. Passenger side is correct.

Get reinforcement plates on those rear shock mounts asap.

Yeah I've heard about the crappy paint coverage on parts of the car that get covered up.

I can't remove the old sway bar end link from my old strut so I'm just leaving it stuck in there and installing new end links on both sides of my new coilovers. Ordered two from Advanced Auto Parts yesterday that have a lifetime warranty as I HAVE to get my car back out onto the road.
Seems like the best deal for now.

Also my new struts came with reinforcement plates so that's definitely a plus.
For installation of the plates, do I just put them over the top of the strut tower before I bolt them down?

I'll clean them off when I get back into my garage later today.

I didn't even notice the washer, oh my gosh.
Wasn't me that put those struts in, but I'll definitely correct that when installing my new struts.

FYI

Quote:
A vehicle will have either a shock or a strut at each wheel, never both. ... The major difference between shocks and struts is that a strut is a structural part of the vehicles suspension system where a shock is not. A strut is also crucial part of the vehicles steering system and greatly affects alignment angles.
The rear of your car uses shocks.

I'm going to guess that these shocks were installed without the the paper body gasket and that is water/dirt intrusion covering the top of the shock tower. Either that or the center of the Rear Shock Mount is separated from the bracket allowing road grim to pass into trunk.

Use E46M3 Convertible RSMs.
And Z3 Rear Shock Tower Reinforcement Plates.

Everyone’s car will look like this with use especially in high dust areas. The trunk has vents on either side that do not seal out the environment well at all. The trunk carpet liners funnel all of the dust and debris to these areas. Shock mount paper gaskets are not going to change anything.

It looks like he has them bent back for the pics. The outside are brown but the inside is a gray fabric.
