According to most people at SEMA, just about all things would be better if they were made form carbon fiber. In some cases, like seat upholstery and dong-shaped hood ornaments, this is not true, but when it comes to performance parts, it almost always is.
We have carbon fiber body panels, chassis, interior parts, and even wheels, but this is new. This is a carbon fiber bellows spring is 70% lighter than a conventional steel spring, and also does flex sideways when under pressure. This means that the new spring doesn't create any side load that increases friction, thus freeing the suspension to move more freely.
Better still, since it's made out of small, modular components it can be assembled to spec by the user, and easily adjusted.
