Problem is these coilvers seem cool and all but until you take them to a kharadiya and get the coil disconnected from the shock absorber there is no knowing as to the condition or operation of the shock absorber which is the first and most important part to die. If the shopkeeper guarantees the condition of the shock only then is this a worthwhile purchase. Corolla's loose their shocks under 30k with rural driving here, but there's not a lot of people who even know this.
