ATI Super Damper – Toyota GR Yaris / GR Corolla / Lexus Morizo RR (G16E-GTS)

The ATI Super Damper is a high-performance harmonic balancer upgrade designed for the Australian-market Toyota GR Yaris and GR Corolla equipped with the G16E-GTS 1.6L turbo engine. Engineered to control torsional crankshaft vibrations across the entire RPM range, it provides critical protection against damaging harmonics—particularly important for performance-driven street cars and track-focused builds commonly seen in Australia.

Unlike the factory unit, the ATI Super Damper uses a proven elastomer-based design to absorb crankshaft oscillations more effectively, helping to improve engine longevity, reliability, and smoothness under sustained high-load conditions.
