Suspension, Improving ride Options

[framos914]

Just got my 75 2.0 back on the road after 24 years in the back of the garage. Last time I drove it back in 94 everything was pretty tight and smooth, now it seems to be all over the place. Was hoping to take it to WCR.
Any suggestions on where to start with the suspension?
Has 76 911S front koni struts, S calipers and sway bar. Rear 914-6 components.
Thanks

Tires are prone to flat spotting if stored in 1 place with weight of vehicle on them. Tires that aren't round don't help ride quality. This can occur on tires that are only a couple of years old. Heck, this happens on new tires even when parked overnight but the roughness will roll out with a few miles of driving. If stored that way long term the deformation will become permanent and will not go away with driving.

I'll also throw out another "out there" theory. Vehicle ride quality of the whole automobile market has improved enormously since 1994. You may have become used to modern ride quality on your daily driver and are expecting a sports car from the 70's to compete. It won't.

Per previous notes - better description of exactly what is occurring will help.

To mepstein's point, the pressure on the side wall is the tire's maximum inflation pressure to carry maximum load at rated tire speed. 26 front/29 rear was placard for the OEM 165 width 15" tires.

Also when you say it was "all over the place"; make sure you're not evaluating on a freeway with rain groves, or on a roadway with tire ruts within the lane. Either of these will make a vehicle wander side to side.
