I have been reading about coilovers....what exactly is the difference between a spring and a coilover???

 

Springs would fit over the stock shocks...coilovers replace the shocks and springs (matched set so to speak)

 

Kinda....Well the official term is springs over the shocks. So by default our P Cars actually have coilover suspensions. Now when you hear coliovers it is generally meant that they are height adjustable and/or dampening adjustable. They are also sold as a matched spring and shock combo where the spring rates and shock dampening is designed to work specifically with each other.
