OK I drive a 97 cavalier and my friend bought a set of new adjustable coilover springs but I don't know what brand they are. He gave them to me for free but the thing is I don't know to put them on or not because I know some brands are good but others are bad. what do you think.

 

First off, I'm pretty sure you're on the wrong forum. Second, unless you're going road racing in your cavy, I don't see a reason to upgrade. But hey, you got them for free so you might as well throw them on there and see how you like them.

 

Adjustability sounds great on paper, but unless you know what you are doing, you can screw things up (handling-wise) in heartbeat.

Ask yourself ... Friend ... new coilover package ... gave them away ... reason?
