Mountain Pass Performance: adjustable rear camber arms installed

[52 16 57 39]

I just installed the MPP adjustable rear camber arms. Last summer I installed the UPP moderate 1" drop springs, so I knew my rear camber needed to be adjusted.

Super simple to install in my garage - only needed a 21mm wrench/socket to remove the 4 bolts holding the rear camber arms in place. Removed the stock, installed the MPP's and then fine tune the rear camber settings.

Here are a few picts of the process once you have the car lifted, supported and rear wheels removed.

@52 16 57 39 not sure if you posted this elsewhere before- what rear camber numbers were you getting before the MPP camber arms after the spring drop? What will you set it to at the alignment shop? Also curious to see what sort of rear tire wear you were getting.

I was running just the UPP moderate springs, but rear negative camber was too much, and the negative values only increase when you carry 3 more adults (wife & 2x6ft teenagers) while under load/compression.

Front camber is too much money to mess around with and it’s pretty static - versus the loads/compressions the rear can have w loads and/or a utility trailer in tow.

December 2020 alignment

The rear camber value of -2.something degrees is too much for my liking - and again that number goes more negative w more load.

Hence the MPP rear camber adjustable camber arms.

I have a camber tool, so I set my values around -1.25 degrees.

Tesla stock values I don’t know - but from the spec values above, -1.25 degrees seems fine, and I might go less.

I just ordered these with my MPP Coilover kit. Im hoping that this will be everything that I need.

We just saw this, thanks for making a great post with photos!

Just in case you adjusted your camber after the alignment - your rear toe will be affected by the camber change. Just keep an eye on your tires!

Thank you again for your support everyone

I had -2.6 camber after my MPP coilovers were installed. Adjusted down to -1.0 after the alignment.

This may sound silly but my MPP camber rear arms had a little adjustment bolt and latch for a "leveling sensor." Does the model 3 have a leveling sensor.

The European and Asian market cars do!

for the 2023 model y performance and the HPP adjust camber arms, wanting longest life from the rear tires, what is the spec for almost vertical tires, no inside edge burn?
