PMY Mountain Pass bearings, coilovers and traction arms

[cbritton3]

I recently installed Mountain Pass Performance's solid lower control arm bearings, comfort coilovers and rear camber arms onto my PMY. I've only had a couple weeks worth of testing everything out, but the driving experience is vastly improved so far.

I know there are numerous reviews out there for the coilovers, but haven't seen any reviews on the solid control arm bearings (for the model Y, at least). In talking with Jesse at MPP he noted this was a mod that would make the biggest difference in the steering response, and he was right on. It's hard to explain, but makes the steering feel more direct, sharp, and crisp. Note that these are for sale under the PM3 section on MPP, and not under the PMY.

I had a heck of a time (in Marietta, GA) finding a shop that would price coilover and bearing install, so finally just tore into it myself. I got a lot of folks that simply didn't want to touch a Tesla (even after explaining similar suspension setup to all the other cars they work on), or just got some astronomical numbers from those that would give an estimate ($2k+).

I purchased a shop press from Northern Tool and used the optional pressing tools that come with the bearings from MPP. I didn't have any experience with a press, but after a few YouTube videos and a few beers found it pretty straight forward.

Huge shout-out to Tesla Mark (not sure his user name on here) for the very thorough YouTube install video, and of course Jesse and @MountainPass for the awesome products.
Cheers,
Chris

@cbritton3 - Nice work! Takes guts to rip into a new car, but I also thinks it’s worth it. Again, this is why I love this community.

Your setup looks so mean. I think I might get a few more MPP goodies to add onto my Coilovers and camber arms. Looks like the control arm bearings and traction arms are next on my list.

i didn't realize they were now offering the bearings for the Y, last time i was on their site those weren't shown for the Y
I will have to order a set to go with all my other MPP parts on my PY

cbritton3, thanks for the writeup! Can you share how you decided on the parts you chose and not the other MPP parts? For the front, you decided to only install the Solid front lower control arm bearings... but not the Corkscrew upper control arms. For the rear, you decided to only install the rear camber arms... but not the toe arms or the traction arms. I want the same setup and would really like to hear your thought process. Thank you in advance!

I had previously settled on the MPP comfort coilovers, and just reached out to MPP on what they suggested. I'm not planning on any track days or anything like that, so Jesse steered me towards these parts for the best bang for my buck.

I like the height you set it at. How much lower did you set the height? Is that the recommended MPP settings for height? Just want to know since I have a set of MPP coilovers going on mine at the end of the month.

I think I went 10mm below the MPP recommendations, both front and rear. The rear springs seemed to settle lower after a week or so of driving around too.

Rear looks pretty slammed… was there anything heavy in the back when you took that photo?

Nosir that's empty inside. The back seemed to settle more than the front did. Both set 10mm below recommended settings from MPP.

My car is currently set at 1.5" lower (MPP spec) and my MPP upper front control arms are notching themselfs on the car. So you might want to keep a eye on that if you are lower (might not be a issue with stock arms)

This looks perfect.

Here was my install.

Mountain Pass Comfort Coilovers, + (almost) the full suite of Mountain Pass Suspension Parts, Installed by European Auto Source on a Model Y P

Just my $0.02 after having them on for a long time, I didn't have my car nearly as low as yours, and I absolutely wrecked my rocker trim panels just from going over bumps at too high of speed. Really unenjoyable. I ended up raising the car, softening the suspension, and I'm much happier now. Still need to replace the rocker panels, but no further damage since then.
