Competition Clutch 1992-1997 Lexus SC300 Stage 4 - 6 Pad Ceramic Clutch Kit
A five-speed Lexus SC300 that has been turbocharged or 2JZ-GTE swapped will chew through a stock clutch quickly, slipping as soon as boost arrives. Competition Clutch 16085-1620 is a Stage 4 six-puck ceramic kit for the 1992-1997 SC300 and the 1988-1997 non-turbo Supra, built for big power and drag launches. It is not a daily-driver replacement for a stock car, and this page explains why so you buy the right stage.
The manual SC300 and non-turbo Supra share a single-disc clutch behind the inline six. A Stage 4 kit pairs a Competition Clutch performance pressure plate with a sprung disc carrying six ceramic pucks instead of a full ring of organic facing. Less contact area with a much more aggressive material means the disc grabs hard and holds far more torque: Competition Clutch rates its Stage 4 line at up to a 250 percent increase over stock. The trade-off is engagement that is close to on-off, more chatter when slipping the clutch in traffic, and faster flywheel wear. The -1620 part number is the sprung-hub version, which is easier on the transmission than the solid-hub -0620 disc. For a naturally aspirated car or a mild build, the 16085 Stage 2 kit is a far better match.
If your car is stock and simply worn out, the usual signs are a high engagement point, a slow slide in the upper gears and judder on takeoff. That is a job for a milder stage, not this kit.
First make sure the problem really is the disc. A roll-on in fourth from low rpm will show slip as the tach running ahead of road speed. A soft pedal, a leaking slave cylinder or oil from the rear main seal can all mimic a weak clutch, and none of them is fixed by a stronger disc. Our slipping diagnosis guide walks through that check, and flare vs slip explains what each feels like. Be honest about the engine's torque: buying more clutch than you need costs you drivability every day.
Our listing covers the 1992-1997 Lexus SC300. Competition Clutch lists 16085-1620 for the 1992-1997 SC300 and the 1988-1997 Toyota Supra 3.0L non-turbo. It is not for the SC400, which was automatic only, or for factory turbo Supras, which use a different clutch and gearbox. Swapped cars vary a lot: if your SC300 now has a different engine, a different transmission or an aftermarket flywheel, confirm the input spline and flywheel pattern before ordering, or send us the year, VIN and a list of swapped parts. More options are on our rebuild kits page.

Competition Clutch lists it for the 1992-1997 Lexus SC300 and the 1988-1997 Toyota Supra 3.0L non-turbo. It is not for factory turbo Supras or the automatic-only SC400.
Usually not. The six-puck ceramic disc engages abruptly and can chatter in traffic. It is made for turbo or high-power builds. A stock or lightly modified car is better served by a Stage 2 kit.
The -1620 disc has a sprung hub, which softens engagement and drivetrain shock. The -0620 version uses a solid hub for maximum strength at the cost of more noise and harshness.
No. The kit includes the performance pressure plate, six-pad ceramic disc, throwout bearing, pilot bearing or bushing and alignment tool. Resurface or replace your flywheel at install.
Competition Clutch rates its Stage 4 kits at up to a 250 percent increase in torque capacity over stock. It does not publish a specific ft-lb figure for this part.
