I recently put lot of money into my Dads1991 CADI STS. He is over 80 and it was his favorite car. One of the most important parts of the work that was done on car was shuck and straight replacement. It was important to me that the car once again drove like it was ridding on glass. I ended up buying a shock/strut combo 4 all 4 tires. The car now feels like a truck driving down the road and I've driven the car thousands of miles to break them in. No dice. I did watch all of the shock and suspension related videos you have, but I'm left with the question is there a shock/strut combo compatible with a 91 STS, that will provide it with that feeling of driving on glass equivalent to the original air suspension again?
Thank you for any help.
Sorry for the auto correct fixing words that did need not corrected.
Not really you have to go back to stock and that's so old good luck finding one. There's no law that says GMS to keep making parts for cars so they don't. But you could try hemmings motor online often somebody there will be able to find just about any car part around
