XClutch Lightweight Chromoly Flywheel Subaru 2004-2021 STI
XClutch Lightweight Single Mass Chromoly Flywheel is manufactured using premium materials and has been precision-balanced for those of you who need a quality OEM flywheel replacement.
Note that this is the lightweight version which will increase the performance by removing some of the rotational mass associated with a conventional flywheel. This promotes a more responsive engine and throttle response. Depending on what clutch setup you will utilize, some chatter can be noticed.
