Spec Billet Aluminum Flywheel – 2002-2005 VW 1.8T 6-Speed (MK4 GTI/Jetta/Golf/Beetle & Audi TT 225/180)
The Spec SV81A is the #1 selling lightweight aluminum flywheel for every 6-speed 1.8T 20V VW/Audi (02J & 02M transmission). Weighing only 10.5 lbs and machined from a single 6061-T6 billet with replaceable 1045 steel friction surface, it drops ~14 lbs of rotating mass vs the factory dual-mass flywheel, eliminates DMF rattle forever, and dramatically sharpens throttle response and rev-matching. SFI 1.1 certified the gold-standard flywheel for 400–700+ hp 1.8T builds.
