Auto Valve Control Stability - AVCS
AVCS is the latest result of our constant R&D effort. With GAB AVCS you can now feel the difference on uneven road, bumpy road, pothole, high-speed corners and highways. The damping and rebound force is automatically turned by AVCS to suit all road conditions. AVCS is an internal system that adjusts the stiffness of the suspension. It uses multiple layer valve spring to sense the road condition and automatically reduces or increase damping force according to the road condition and your driving style. The result is superior handling and maximum comfort on all road condition without having to manually tune or adjust the absorber.

Mono-tube structure
Use of mono-tube generates linear damping force, which reacts to even a tiniest input from road surface, and stable damping force, which can be well maintained even for intensive circuit run.

Mono-tube with Auto Valve Control Stability (AVCS)
Maximizing road holding and comfort, ST series provides solid feeling just like sophisticated European sport vehicles, without sacrificing ride comfort.
