FactionFab V2 FL-Spec Street/Track Coilovers

The FactionFab V2 FL-Spec Coilovers are designed to provide an ideal balance between street comfort and performance handling, making them an excellent choice for daily-driven vehicles, weekend builds, and cars that see occasional autocross or track use.

V2 FL-Spec Street/Track Design

The FL-Spec is engineered to bridge the gap between a comfortable street suspension and a more aggressive track-oriented setup.

Spring rates and shock valving are positioned between FactionFab's F-Spec and FR-Spec systems, providing improved handling and chassis response while maintaining a level of comfort suitable for regular street use.

A rubber-isolated pillowball upper mount is paired with an adjustable camber plate to provide a balance between responsiveness, adjustability, and ride comfort. The rubber isolator helps absorb road and chassis vibration that would otherwise be transferred through a solid-mounted upper mount.

Shorter shock bodies and springs provide an increased range of ride-height adjustment, allowing greater flexibility when setting up the vehicle's stance and suspension geometry.

30-Way Adjustable Damping

With 30 levels of damping adjustment, the V2 FL-Spec allows drivers to fine-tune suspension response based on road conditions, tire setup, alignment, driving style, and intended use.

Softer settings can be used to prioritize street comfort, while firmer settings provide increased response and chassis control for spirited driving, autocross, or light track use.

FactionFab testing has shown up to a 0.12G increase in cornering performance on firm settings compared to soft settings in tested applications.

Actual results may vary depending on vehicle setup, tires, alignment, driving conditions, and other modifications.

• All-new components from top to bottom

• Revised application-specific spring rates

• Expanded 30-click damping adjustment range

• Offset camber plates for increased negative camber adjustment after lowering

• Refined spring rates and shock valving

• Increased ride-height adjustment range
