Hi guys,
one day my friend asked me the difference bettweeen spring and coilover and i couldn't answer him, i never thought about this question and always thought they are the same thing, but then i just realized that coilover is so much more expensive. Can anyone tell me thanks.

 

besides difference in price, some coilovers come with their own shocks and they also allow you to adjust the ride-height of your car as opposed to springs where they're not adjustable.
someone please correct me if i am wrong or left something out...
