Everytime I drive in my cougar it seems the ride could be alot smoother. With most of the roads I can feel the texture of the concrete through my car, even brand new concrete roads. Even with the slightest bump it will be multiplied to what a big bump or chug would feel like. The cougar is a 1996 Xr7 with 87,000 miles. Do I need new shocks or springs or both? Thanks for your help!
