need some advice
thank you
And I'm not trying to be a smartass but are you folks "overweight" by any chance?

btw do i need to change both springs and shocks or just shocks only ?
No, you don't have to do springs and shocks at the same time. If there is nothing abnormal/broken with the suspension, try a set of good shocks.
These cars have an extremely simple suspension design. Take a good look before you buy anything.
