964 rear end travel?
I have a new to me ~55K mile 92 C2 Cab.
When putting it through its paces on road I've noticed what feels like
some side to side travel, I'd almost call it sway in the rear end. Especially felt in moderate speeds when I turn in. To me it feels like the rear suspension travels sideways, then takes a set. It sort of feels like oversteer, except the tires are planted. Only moves enough for me to think -- did that just happen?
I've never driven an early stock 911, so I really don't know whether this is normal or not.
My wife's stock 993 feels solid. A former 996 I had felt like the 993 from a rear end perspective.
The car is completely stock -- and if that's normal -- I'm fine with it -- I'll learn to deal with the character, however, if its a sign of something has tired -- then I'd like to get it replaced.
I'm not interested in upgrading -- or firming up what is otherwise stock -- I have plenty of track toys to waste my money and kidneys on :-)
thanks,
Mike

The car's rear suspension is engineered to have active geometry called the Weissach-effect, however after 25 years and all those miles, I guess the rubber bushes don't keep control of the geometry like they used to.

My very clean non-worn 964 was floppy. Replacing every joint with a monoball fixed that!!! :-)
Check the spring plate and swing arm bushings. Also check the rear shocks are good. And the engine mounts.

I would check the engine mounts first. They are notorious for failure. I bought 993 engine mounts from Pelican and they worked well. Avoid buying mounts on ebay.
Search this forum for engine mounts and you will get plenty of results. Good luck!

It's easy to check for sagging motor mounts:

Thanks folks -- I'll check the engine mounts (and other ideas) the next time I head out to my storage garage!
