have any of you heard of progress springs for our car? my cuz said they are good for our car but i have never heard of them. if anyone has em or knows someone that does reply so i know if they are good.

 

he might have been refering to "progressive springs" they arent a brand of spring rather a design in where the spring has more dense coils at one end versus the other giving a better ride, do a search and there are some post wiht pics that show the difference between progressive and non progressive
