My question concerns the different articles of suspension on an car: 1. What is the difference between Springs and Lowering Springs? 2. Are Shocks incorporated into Dampeners or are they two totally different things, if they are, how are they "connected" to eachother? 3. Where is the Strut's location in correlation to the Coilover? 4. Would Lowering Springs replace the "Springs" on a Coilover?
