how do you know if your suspension is worn. I had it checked a year ago but im not sure if the mechanic knew what he was doing. I have an extremely rough ride, wich i know is normal but when is it too rough? Is there a rule of thumb? thanks for any help
on an unrelated and somewhat silly question, my 87 trans am with a 305 tpi has a plastic badge saying performance suspension underneath the leather pouch glove box. Looks authentic and the car is not riced out. Is it stock and does it mean anything. I dont have the rpos thanks again i know very little but am learning thanks to a great deal this site

 

there is no way to tell, except individual parts. a performance suspension will be stiffer than one made for ride quality, so that's you sacrifice. If you're not pleased with how it rides, I'd suggest new shocks, struts, springs, and also to set your air ressure int he tires at around 30-32psi
