ATI Super Damper for the Subaru BRZ - Scion FRS FA20 Engines.
ATI's Super Damper (Part # 918482) for the Subaru BRZ and Scion FR-S 2.0L boxer engine is designed for both street and high performance racing applications. The new aluminum-shell, steel-hub damper features a 10% underdriven belt drive that works with the OEM belt set-up. It's a direct fit replacement for the stock OEM unit and is better capable of handling a wider variety of driving habits that owners will put their new cars through. OEM dampers are optimally tuned to a narrow band of perceived normal driving conditions and do not perform well outside of those limits. The ATI Super Damper can handle any engine speeds and driving conditions that get thrown at it to better protect your engine. ATI Super Dampers provide balanced dampening of torsional crankshaft vibrations through all RPM ranges and exceed SFI 18.1 Safety Certification for competition use.
