Before we could install the new shocks, we had to remove the old rear springs by unbolting the outer control arm from the knuckle and swinging it down to remove the spring.

The BC Racing Coilover Kit has an adjustable rear spring perch to adjust the rear ride height.

The large diameter spring perch and the bending moment of the spring makes this perch a little more difficult to adjust while in the car.

The spring was pretty easy to install and the lower arm was bolted back to the knuckle.

The rear shock was then bolted in place.

The rear shock adjuster is pretty easy to reach once jacking the rear of the car up.

For some reason I cannot see any photos using multiple browsers.
Are the photo links broken?
Seems fine to me
BTW, is there no “tesla,” section under projects?
The stock upper control arm design is the real story here, and it is good to see it called out. A plastic and steel hybrid arm with a water-trapping ball joint is a failure waiting to happen, especially on a car that sees rain and road salt. Replacing it with a one-piece forged aluminum arm is the right fix, not just a performance upgrade. My tip for Model 3 owners hearing a clunk over bumps is to check that arm first and not let a shop replace the whole strut assembly when the arm alone is the problem, because the cost difference is large and the arm is a known weak point on these cars.
The new Tesla Y-L seems to have a magnetic damper in the rear. It would be interesting to see what the aftermarket brings out for that, that still works with the dash settings, but offers better valving or perhaps an aftermarket controller that offers even more settings than comfort and standard.
