does anyone know what the difference is between Competition/Pro Series & Pro Series Springs by Eibach if there is any. i'm thinking of getting a set of Competition/Pro Series Springs by Eibach for my v6 2004. it's my everyday car

thanks in advance

 

This belongs in the suspension forum. Also... read the sticky in the suspension forum.

Race grade springs should be on RACE CARS. not street cars. V6's should stay at the bottom end of the spring spectrum or you'll ride horribly and handle bad enough to wreck.
