I now have the adjustable comforts installed for two months and would like to share my experience. As many has said, this is a great suspension that that car should have come with!
I installed this together with the solid lower control arm bearings, new forged 19 inch wheels (Jova) and a new set of tires (crossclimate2). I went through a unique experience, as one of the customers that mountain pass sent the wrong nonadjustable version of the coilovers. This led to two phases of installation
, first just with one control arm bearing on the left and the new wheels and tires. Somehow these had already made the car drive with a night-and-day difference. It felt so much more nimble with much sharper turns, but of course the car was still floaty. Mountainpass was very responsive and sent the correct version immediately (great customer service). The coilover took away the floatiness but not having any harshness and the car felt, just great. It reminded me the feeling when I first got the car 3 years ago, like many said, it puts a big grin on your face every time you drive it, again. The only "drawback" is my safety score on the Tesla app is reduced to 93 due to "aggressive turning" (I don't track the car
).
I did the recommended lowering. The car sits at a perfect stance now, see attached before-and-after picture.
One comment is that MountainPass should really emphasize in the installation guide the issue of putting lubricant on the springs. There was a thread on it. Since not many had mentioned it for a while so I did not pay much attention and put on some lubricant to make the height adjustment easier. This led to the infamous clunking sound when turning at the extreme. Luckily after flooding it with brake cleaner twice in 2 weeks and then driving for 2 months, it mostly went away.
Finally an issue/problem I hope some experienced people can help. I always hear a light clunking sound when driving at low speed (10 to 20 mph) and going over small cracks on the road. It almost gives the feeling that some screws are loose. However the sound is not obvious or any louder on big bumps or at high speed. I thought this may be related to the lubricant issue. But it did not get any better, maybe even slightly worse now. I'm going to take it back to the mechanics next week. Would appreciate any suggestions on what the problem may be.
