A suspension kit, “sport” or “coil over” must be designed and built specifically for the car it is to be fitted to. The characteristics of the valving are specific for the model of car. Cheap coil over kits are not model specific and one damper design can be applied to 20 different cars all of which have differing characteristics, this keeps the cost of kits down.
It is also one of the reasons they ride poorly and generally hard. One way to know if a damperkit is not model specific for the application is if the kit comes with a camber plate at the top and screw off bottom brackets. The easiest way to get one shock to fit many cars is to supply a camber plate to adapt one top pin design to fit many cars shock mounting points.
Please also be aware that Rose jointed camber plates are noisy. Generally these noises are excluded from the warranty as manufacturers know they will never be able to stop this noise. Also as the bearings wear, the noise gets worse! Expensive coil over kits are model specific and custom designed exactly for the application and this is why they are expensive, they will never come with camber plates as the use of the original mounting is the most desirable way to do it.
