bring it back to the dealer and ask them to check your shock. I remember, there was one of the member had his shock blown.

As the tires wear past their half-life mark they will get noisier and pick up more vibration from the road. Don't know how tires would make the ride stiffer, though.

I do still see the weights there though and my tire psi is what they suggest. anyone else experience this? could the tires be more worn now so i am feeling more or maybe the shocks?

i got rid of my firebird for these reasons and never imagined i would have this with a luxury car. i have yet to take it to the dealership yet to see what they think. i have not hit any potholes and always take it slow over the few speed bumps i encounter. i drive mostly highway miles. i don't think it's out of alignment as it tracks straight when i test it from time to time.

thanks for your time!

When was the last time you checked the air in your tires. Should be done at least once a month as a 10 degree change in temperature can effect the pressure up or down in your tires. I'm sure you already know this but always check your tires when they are 'cold'.

When I test drove the car I bought I told the salesman 'man, this car rides hard' he said it felt normal to him. On the way home I stopped and checked the tires. They had 45 pounds of air in them. After I dropped them to 35 pounds all around it was like I had just bought a Buick or something. So check them out...
Just a thought for you...
