Rear end break away

2013 SS. The rear end seems to break away more often than I was expecting. {Was previously driving a G8, the best handling car I have ever owned.} Recovers quickly and perfectly, however.

Has this been anyone else's observation?

Common side effect of soft subframe bushings. Time for an upgrade!

Spot on Jeremy.

Oldag,

Rear end step out is common with the Camaro. It is so common we sometimes forget to check alignment. If the rear toe is not set correctly the rear end step out is dramatically increased. Find a quality alignment shop and have them align to these exact specs.

Front Toe 0.00
Front Camber -1.00
Rear Toe IN 0.10
Rear Total Toe 0.20
Rear Camber -.050

Your steering will feel more on center. Hard acceleration will be improved along with turn in and a slight reduction in understeer.

as stated above the booty on my car liked to move around till i got bushings and an alignment change. Alignment helped a surprisingly amount and the bushings just made it perfectly predictable and stable...i am auto so standard might have different results.

Exactly what I'm doing with mine for the same reason. Pfadt solid subframe bushings + rear trailing arms & toe rods.

There are a few things you can do to help that, but they are hitting it right on the head. Give us a ring or shoot a PM if you have any more questions!

Getting tires mounted at tire kingdom this weekend lol. I have a friend that works there so I'm going to see if he can do an alignment to those specs. Thanks for the info guys.

how different are those specs from the OE specs? mne is currently aligned to factory specs and yea...i can step the ass out at will. wouldnt mind it being a little more planted, although that is fun from time to time haha.

OE specs have a rather wide green range. To compare your alignment to the specs I have posted would require you posting your exact alignment.

Yes they are in degrees.
Motion from the sub-frame does contribute to a loose rear end, but if the rear toe is off it wouldn't matter if it was welded on. Rear Toe should be IN 0.10 or more up to 0.12. Total Rear Toe should be IN 0.20 or 0.24. Matching them side to side is very important.
