SPEC part number SP291 is the Stage 1 clutch for the 1986-1990 Porsche 944 Turbo. Stage 1 is SPEC's mildest performance step: a molded, high-performance organic lining that SPEC says offers smooth engagement and excellent life. Nothing about it changes how the car drives day to day, the pedal, the take-up and the noise stay stock-like, it simply adds holding capacity, which SPEC rates at 310 lb-ft for this part number. That makes SP291 the right choice for a 951 running stock or lightly-boosted power that has worn out its original clutch, rather than a built car chasing a big number. SPEC lists Stage 1 as suitable for street, drag, drift, road race, rallye, pulling and autocross, the broadest usage rating of any SPEC stage. No flywheel is included and SPEC does not list one as required for this application.
