MountainPass Performance Comfort Coilovers

[Sudsington]

I wonder if multiple adjustments in the same direction of the spring perch could cause this? You'd be "twisting" the spring a bit? I haven't experienced this but I've adjusted my car up and down.

I'm not certain (low level of knowledge on my end), but I have about ~3k miles on the coilovers and haven't adjusted the height since it was installed. Will update as I learn more though.

After the installation of my MPP coilovers, when turning at low speeds, there is an audible "ping" noise. It looks like when I turn the tires, the springs rotate which causes the noise.

I have looked at other chats for a fix, but the consensus is that it's something that we'll just have to live with.

Anyone here experience the same thing?

Mine same, took back to installer and it helped but still there or coming back

Thanks for the replies. All align with what i've been seeing and what my installer said. I'm surprised that this happens so sporadically and so often and not addressed in any way by @MountainPass. I have taken it back to my installer several times, costing me extra money to try and fix. They have tried adjusting it with no success.

My installer has done several KW coilover installs on Teslas and other cars, and shared with me that he sees in roughly about one-third have this problem.

I'm happy with the ride, but very, very annoyed by the noise.

MPP Comfort Coilover making ping sound when turning wheel

Please, test Teflon rings - apparently plastic perch is not slippery enough... Coil should be either permanently fixed or slide freely to remove that noise.

Thanks for the link. I tried to search for duplicate chats before posting, but I didn't see this one.

This was very informative. For those interested, here's a summary of the helpful posts:

“The spring needs to not move at all, and we have found often that customers (or shops) are spraying lubricants all over them during the installation. Making sure they are clean and dry should resolve it, and the dirt and dust from driving on the road will also help to keep the spring still as time goes on.”

“I can confirm that dousing the perches in brake cleaner on subsequent days completely eliminated the pinging.”

“Wanted to update this thread. I appreciate Jesse sticking with me through all of this. I took the coilovers off and sprayed the mating surfaces between the spring and the perches with brake cleaner. Wiped them down thoroughly. Put them back on, and the springs stopped moving by a lot. I then sprayed them down the next time I had my wheels off. This time, the remaining movement had has gone away. Looks like any grease or lubricant that comes into contact can cause the spring to move. Spraying it down with brake cleaner has solved the issue for me.”

Thanks for the summary. I had that question when I was evaluating MPP or Unplugged coilovers. The Unplugged had Teflon rings and I wondered why the MPP didn't and asked Jesse and he replied it wasn't needed but didn't go into details. I figured I would just follow the instructions to the letter and since it didn't mention any lubrication, I didn't use any and I haven't had any issues. I guess I lucked out because my first impulse is usually to apply anti-seize or grease to things.

I also did NOT use any sort of anti-seize or lubricant when I did my MPP install several weeks ago. I have heard no squeaks and love the comfort coilovers more with each drive.

 

[Rootboy]

So MPP uses KW to build their coilovers, I have used KW coils on other cars before and loved them, UPP doesn't say who they use to make theirs but i am sure they are also made very well,

I'm familiar with KWs as well. Reputable company. Should we expect other shops to jump on the aftermarket suspension wagon?

everyone that is lowered, did you trim your mudflaps because mine scrape!? I have the OEM Tesla ones.

I'm lowered ~1.5" on Eibach springs (LR), and I scrape my OEM flaps on everything. I had two sets that were made of rigid plastic, and both snapped off within days of installing them. So far so good with the OEM flaps due to their flexibility.

 

[Ruffles]

I use these mud flaps from Nansure that I got on Amazon. You can see from the first picture they are much shorter than the factory ones (factory left, Nansure right) BUT they are hard plastic and don't flex. I still hit them on occasion on some speed bumps and when I do, they break (which is why I have 3 boxes of them lol).

I trimmed my mud flaps.

 

[pwrusr]

Go lower!?

Still seems high. Middle hub to fender is 15.5 inches ~393MM about 2 sausage finger gap

Perfecrt for daily driving

 

[MountainPass]

Can we coin the phrase "dragging flap" for these mudflap situations?

I knew a girl in college who was also referred to as "dragging flaps"

Just to give an update, the sound is going away on its own! As i continue to drive it, the sound isn't as apparent and at times it is non-existent.

This adds credence to the suggestion that it is/was due to excess lubricant.

Glad i procrastinated and didn't pay money to clean it all away!

I installed my coils this weekend and noticed something interesting one of the rear shocks did not extend when I cut the white strap. Is this normal?
