Not trying to be argumentative as I am truly interested in the purpose of such an item.

Not taking it as argumentative, I'm glad that you have asked such a question actually.

That question can be posed about pretty much any upgrade on any car. The car already comes with a suspension, why replace it? The answer is plain and simple: pure performance.

Flatter cornering, less deflection in the suspension joints and more consistent grip levels associated with the contact patch being planted on the pavement. The OEM suspension is fantastic, no doubt about it. But there are many concessions made in the interest of mass production and cost cutting that leave there more to be desired. Plus most cars from the factory are set up relatively soft which can overload the outside tires in a turn. One way to get the car to perform better is to simply get each tire perform more equal work when going around a turn and you do that by stiffening things up a big with bigger anti-roll bars and coilovers with upgrade spring rates, to name a few. This is stuff that the factory can not install for a variety of reasons, some having to do with costs and other associated with perceived ride quality.

The adjustable coilovers in this thread actually RETAIN the full functioning Mag ride system that you bought the ZL1 for but makes it lighter weight, and adds ride height adjustability and stiffer spring rates to hold the car up a bit more in turns and lower it to the ground for a slightly better aero profile and flatter cornering. All of this contributes towards more grip and better performance.

Any more questions please ask!
