6112 coil powdercoat failure

is this normal? spider cracks all over the coil’s powdercoat. passenger side looks fine.

 

Where?

 

all the spider cracks in the coils powdercoat

 

Not what, but where?

 

on the coil. zoom in

 

You mean the dirt?

 

It looks normal

 

Can you wipe the coil so we can see what is going on plz.
I think I see cracking but also have to agree with above and looks dirty

 

All the striations are going the same way. Looks like it was dragged across something before it was installed if anything.

 

right- those are what im talking about. those were not there when i installed them about a year ago.

realistically, im probably just tired from lack of sleep amd over analyzing shit. (got a 2 month old at home)

 

Try cleaning the coils before inspecting. Looks like dirt. Congrats on the newborn.

 

thanks!

i just cleaned it off, looks like hairline cracks. i wiped wd40 on them and walked away. i had wipe all my shit down. the salt destorys bilsteins. youd think they would have a better coating at this point.

 

I see exactly what you are talking about and it looks like you are right, it looks like cracked Powdercoat... I would reach out to bilstein if they are really only a year old and yoi bought them new. IF they are cracking like that now, wont be long before moisture gets under there and starts the rust.

That is if you can verify it is cracking, I cant imagine what else would make that pattern.

 

ill call em tomorrow.

 

Spry them with clear cost this time if so

 

IF they are indeed cracks we are seeing Id bet they take care of you in one way or another. Powdercoating is done in batches and pretty easy to mess up, Not enough degreasing of part prior, too thick of coat, too thin of coat, not enough heat while baking, too much heat while baking, cooldown to quick, too long of a bake, not long enough, etc etc... Im not sure if they use a special process or powder for a coil as they see so much flexing, but that adds some complexity as well and it looks like they are stress cracks from the movement of spring.

Let us know what they say

 

cleaner photo. talked with bilstein. he said something doesnt look right, so i also at this point contacted headstrong. bilstein will probably want to look at the coils, which they are on my DD, so thats not going to work. so ill probably have to eat it and buy new coils.

also- i wiped the face- not dirty, thats rust coming through

 

Seem sus. What does the coil identify as?

 

ide get your new set ceramic coated, if you do get a new set.
