It does that job well on a stock car, but a tuned four-cylinder puts torque through the damper that it was never rated for, and a failed DMF is a transmission-out repair in its own right.\u003c\/p\u003e\n\u003cp\u003eA SPEC billet single-mass aluminum flywheel replaces it with one solid piece. Nothing inside can wear out, and it cuts rotating mass — which on a 2.0-liter four is very noticeable: the engine picks up faster, settles faster between shifts, and the car feels considerably more alert.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSBN20A\u003c\/strong\u003e — billet aluminum, N20 \/ N26 applications, 15 lb\u003c\/li\u003e\n\u003cli\u003eSingle-mass billet construction — no dual-mass damper to wear out\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003eOne SPEC billet aluminum flywheel with mounting hardware, as supplied by SPEC Clutch.
