Once the clutch starts slipping in the upper gears there is nothing to adjust — the disc is done. SPEC's single-disc kits are the straightforward replacement: a direct-fit clutch with a real torque margin, in a range of stages so the disc material matches how the car is actually driven.\u003c\/p\u003e\n\u003cp\u003eTwo families are offered here. The \u003cstrong\u003eratcheting (SAC) kit\u003c\/strong\u003e uses the factory self-adjusting pressure plate design and works with either the OE dual-mass flywheel or a SPEC billet flywheel — the simplest swap, and the one to choose if the DMF is still healthy.
