SPEC part number SF873FLPR is the Stage 3 Plus clutch for the 1999-2004 Mustang Cobra and Mach, plus the February 2001-onward V8 GT. SPEC's Stage 3+ uses a carbon semi-metallic full faced disc, which SPEC credits with unparalleled life, friction co-efficient and drivability — a full-face material rather than the six-puck used in plain Stage 3, so it grabs hard without the on/off bite of a paddle disc. SPEC rates this part number at 875 lb-ft.
The LPR in the part number is not a marketing suffix. On SPEC's own application list this kit is the version supplied with the optional low pedal requirement pressure plate — a cover engineered for reduced pedal effort, which is the whole reason to pick SF873FLPR over SPEC's standard-effort Stage 3+ cover for the same car. This listing is the 10-spline disc. No flywheel is included and SPEC does not list one as required.
