Thunder Lane Height-Adjustable Coilover Spring Kit - Porsche 992 Carrera

The Porsche 911 (992) TL-HAS Height Adjustable Spring Kit is Thunder Lane's height-adjustable spring system for the 992 generation 911 — lets you dial in ride height on your factory (or factory-sized) dampers without moving to a full coilover. Front Lowering Range: 15-35mm (0.6-1.4 in) Rear Lowering Range: 20-40mm (0.8-1.6 in) Height Adjustable, Factory-Damper Friendly, Excellent Ride TL-HAS lowers the car and lets you set front and rear ride height independently, while keeping the factory suspension — including electronic damping control — fully active. It's the clean way to get a corner-balanced stance and improved handling on a car you want to keep largely OEM. Thunder Lane design allows for great ride and great handling and predictability with the use of helper springs. while this is typically a more expensive solution than a single progressive spring, it allows for more consistent handling on the street and at the limit on track, while still being comfortable for daily driving.
