Best Mk4 Supra Clutch Kits: McLeod vs ACT (2JZ-GTE)

The best Mk4 Supra clutch kit for a boosted 2JZ-GTE is the McLeod RXT 1200HD twin-disc, which holds up to 1,200 hp while keeping a streetable pedal — but a single-disc ACT kit is the smarter buy for a daily-driven build under roughly 600 wheel horsepower. The 1993–1998 Toyota Supra Turbo left the factory with 320 hp and 315 lb-ft, and its stock single-disc clutch starts slipping the moment you add boost. This guide compares five clutch and flywheel options we sell and install at NLP Performance, with real torque ratings, disc configurations, and prices from $523.66 to $1,745.00.

Why the Mk4 Supra Needs a Clutch Upgrade

The stock Mk4 Supra clutch holds factory power and little more. The 1993–1998 Toyota Supra Turbo (chassis code JZA80) makes 320 hp at 5,600 rpm and 315 lb-ft at 4,000 rpm from its sequential twin-turbo 2JZ-GTE, routed through a Getrag V160 six-speed. That single-disc organic clutch was engineered around roughly 320 hp of crank torque — and the 2JZ-GTE is famous precisely because it makes far more than that with basic bolt-ons.

Here is the reality we see every week in our Tampa shop: a stock or lightly modified Supra clutch begins to slip somewhere around 400–450 wheel horsepower. Bump the boost, fit a bigger single turbo, or add a front-mount intercooler and fuel, and clutch slip under load becomes the first thing standing between you and the timeslip you paid for. A slipping clutch also glazes and overheats, so ignoring it usually means buying two clutches instead of one. Upgrading the clutch is the single most important drivetrain job on any boosted 2JZ.

Twin-Disc vs Single-Disc: Which Supra Clutch Is Right for You?

A twin-disc clutch uses two friction discs instead of one to roughly double the torque capacity without doubling pedal effort, which is why it is the standard choice above about 700 hp. A single-disc clutch uses one upgraded disc and a higher-clamp pressure plate; it is lighter on the wallet, simpler to live with, and plenty for most street builds. The right answer depends entirely on your power goal and how you drive.

Choose a twin-disc if you are chasing big power

Twin-disc kits like the McLeod RXT split clamping load across two discs, so they can hold 800–1,200 hp while still engaging smoothly enough for daily use. That is the McLeod advantage on a 2JZ: streetable manners at power levels where a single disc would need a brutally stiff pedal or an on/off race puck. The trade-offs are cost and a slightly heavier rotating assembly.

Choose a single-disc if you drive it on the street

A single-disc ACT Heavy Duty kit is the value pick for street and street/strip Supras up to roughly 600 wheel horsepower. You get a big jump in clamp load over stock, a familiar single-disc feel, and a price under $930. For a daily-driven JZA80 that sees occasional track time, this is usually all the clutch you need.

The 5 Best Mk4 Supra Clutch Kits Compared

1. McLeod RXT 1200HD Twin Disc — Best Overall

The McLeod RXT 1200HD is built for the high-horsepower street/strip crowd and is rated to handle 1,200 hp. Two ceramic-lined discs share the clamping load, so it grabs hard enough for a big single-turbo 2JZ yet engages with a moderate pedal effort you can actually commute on. It ships with a steel flywheel and is offered in the correct spline for the factory V160 six-speed as well as popular T56 swaps, so you order it to match your exact transmission. If your goal is 700–1,000+ wheel horsepower without turning your Supra into a track-only car, this is the kit we reach for first.

2. McLeod RST Twin Disc — Best Value Twin

The McLeod RST is the economical way into a twin disc. Rated for 800 hp, it uses organic-lined discs that deliver smooth engagement with a soft pedal — genuinely the easiest twin to drive in stop-and-go traffic. At $1,395.00 it undercuts the RXT by $350 while still doubling the friction area of a single disc. For a street 2JZ making 500–800 wheel horsepower that you don't want to feel every time you pull away from a light, the RST is the sweet spot.

3. ACT HD/Perf Street Sprung — Best Value Overall

ACT's TS4-HDSS kit pairs the company's most popular Heavy Duty pressure plate with a sprung performance street disc. The HD pressure plate uses an exclusive diaphragm design and a four-stage heat-treat to raise clamp load well above stock while preserving clutch life and a streetable feel. The sprung hub soaks up driveline shock for smooth take-up, so it behaves like a factory pedal with far more holding power. For a daily-driven Supra under roughly 600 wheel horsepower, this $927.90 single disc is the best money-to-capacity ratio in the lineup.

4. ACT HD/Race Sprung 6-Pad — Best for the Track

Want maximum grip for launches and road-course abuse? ACT's TS4-HDG6 wraps the same Heavy Duty pressure plate around a 6-pad sprung race disc. The reduced-contact pucks bite harder and shed heat faster than a full-face street disc, which is exactly what you want when you are dumping the clutch at the drag strip. The sprung hub keeps it drivable on the street, but the engagement is noticeably more aggressive than the performance-street disc. At $925.20 it is priced almost identically to the street kit — the choice between them is really street manners versus track bite, not budget.

5. Fidanza Aluminum Flywheel — The Supporting Mod

A flywheel is not a clutch, but it is the mod that transforms how your new clutch feels. Fidanza's aluminum flywheel is machined from 6061-T6 aluminum to cut rotating mass from the factory's heavy steel unit, so the 2JZ revs up faster and blips more crisply for smoother heel-toe downshifts. It uses a replaceable steel friction insert, so you refresh the surface instead of buying a whole new flywheel. Pair it with either ACT single-disc kit at $523.66; the McLeod twin-disc kits already include their own steel flywheel, so you do not need this with an RXT or RST.

How to Match Your Supra Clutch to Your Power Goal

Match the clutch to your wheel horsepower, not your ambitions. Buying far more clutch than you need means a stiffer pedal and rougher engagement for no benefit; buying too little means slip and a second purchase. Here is how we spec clutches for JZA80 Supras at NLP Performance:

• Up to ~600 whp, street-driven: ACT HD/Perf Street Sprung ($927.90). A single disc with a factory-like pedal is all you need.
• Track and drag focus, similar power: ACT HD/Race Sprung 6-Pad ($925.20) for harder bite on launches.
• 500–800 whp, comfort-first street car: McLeod RST Twin Disc ($1,395.00) for the softest twin-disc pedal.
• 700–1,000+ whp, big or single turbo: McLeod RXT 1200HD ($1,745.00) for streetable 1,200 hp capacity.

Beyond the Clutch: Finishing the 2JZ Driveline

A clutch upgrade is the first drivetrain job, but a serious JZA80 build usually pairs it with handling and exhaust upgrades to match. If your Supra still rides on tired 30-year-old dampers, the KW Variant 3 coilover kit ($3,094.00) adds independent compression and rebound adjustment so the chassis can actually put the new grip down. On the exhaust side, the HKS Hi-Power titanium racing exhaust ($1,908.00) frees up the sequential-turbo system and drops weight. When you order any of these clutch kits, confirm your exact transmission and spline count with our team so we ship the right part the first time — every kit here is in stock and ships from a US warehouse.
