TA-Height Adjustable Design:

The TA-Height (Technische Alternative Height) design allows you to adjust ride height independently of spring preload. Traditional coilovers adjust height by threading the spring perch up or down, which changes spring preload and can affect ride quality. The ST TA-Height system separates height adjustment from spring preload, allowing you to dial in your perfect stance without compromising suspension performance or ride quality.

Lowering Range 1.2" - 2.0":

The adjustable lowering range of 1.2" to 2.0" (30-50mm) front and rear allows you to choose your ideal stance. Lower the car 1.2" for a subtle drop that maintains practicality, or go the full 2.0" for an aggressive show stance. The wide adjustment range makes these coilovers suitable for daily drivers, weekend warriors, and show cars alike.

Premium Dampers with Optimized Valving:

ST Suspensions engineers each coilover application with specific damper valving optimized for the vehicle's weight, suspension geometry, and intended use. The premium dampers provide excellent control without harshness, maintaining ride quality while improving handling. The dampers are designed to work perfectly with the included progressive rate springs.

Progressive Rate Springs:

The progressive rate springs provide a comfortable ride during normal driving while offering increased support during aggressive cornering. As the spring compresses, the spring rate increases, providing more resistance. This progressive characteristic allows the suspension to be comfortable over small bumps while remaining controlled during hard driving.

TÜV Approved:

TÜV (Technischer Überwachungsverein) approval means these coilovers meet strict German safety and quality standards. TÜV approval is required for aftermarket suspension components to be street legal in Germany and many other European countries. The included TÜV certification documents provide proof of compliance.
