Car MS60, with 19" wheels and coil suspension. The car didn't feel stable at freeway speeds so I got the alignment checked. The Ugly Car had almost a half inch of total rear Toe Out... this is a dangerous amount of rear toe out. This much toe out causes the rear to steer the car under acceleration and braking. The car has felt unstable since the first day I got it. The number of alignment problems with this car is getting scarey high... Tesla needs to look into this and take corrective action. The Bad Based on a few posts here, I had assumed that coil suspension cars had closer to -1.2 deg of camber in the rear. Well, my car has -1.9 deg of negative camber. Looking forward to wearing out my rear tires in 8,000 miles like the cool air-suspension, 21" wheel guys! Not sure why there is such a variance in rear camber on these cars?! The Good Caught this before it caused an unsafe incident and before it destroyed my rear tires. It's a completely different car after the alignment. Stable, confidence-inspiring, very happy with straight-line performance and handling! Conclusion If your car feels: Floaty, unstable, steers itself, sways, fishtails... please get your alignment checked. I believe all these problems are related to alignment. Alignment Went to my local custom alignment shop: I sat in the car while they aligned it (so it's aligned to my body weight). In the front I went with a hair toe out. Basically zero toe, but front toe out helps with turn-in response. I was planning on running more negative camber in front, but once I learned how high my rear camber was, I decided to stay conservative with camber in front, and plan to rotate my tires often. In the rear, went a little heavy with toe-in: ~3/16" each side. With this, I shouldn't get any toe-out under hard acceleration nor braking. In the words of lolachampcar, "More rear toe-in will add straight line stability at the expense of range and, to a lessor degree, tire wear." Given the hot-mess my car has been since I got it... i'm all-in for straight line stability. Highly recommend this shop for anyone in the Los Angeles, CA area.
