AASCO Fitment Guide

Upgrade your manual Porsche 991.2 Carrera or 991.2 GT3 with an AASCO lightweight billet steel single-mass flywheel designed to reduce rotating mass and dramatically improve engine response while retaining the OE twin plate clutch setup. This 18.5 lb lightweight steel flywheel is designed for select Porsche 991.2 manual applications using the factory twin plate clutch configuration, helping the engine rev more freely, respond more sharply, and feel more alive during downshifts, heel-toe shifting, and spirited driving.

At DasMotoring, this is one of our favorite upgrades for a manual Porsche. A lightweight flywheel can completely change the character of the car — making it feel sharper, more mechanical, and more connected. If your 991.2 manual 911 has started to feel a little too slow or soulless, this is one of those upgrades that can reignite your love for the car and give it some of that 911 S/T-inspired character and flair.

We have run AASCO lightweight flywheels on our own manual Porsches for years through daily driving, traffic, backroad driving, and track use with excellent results.

This is a great choice for drivers looking for a more responsive, motorsport-inspired feel from their manual 991.2 while retaining the OE twin plate clutch configuration. The AASCO flywheel is a lightweight steel design, which can be a nice balance for street-driven cars that want sharper response without moving to an ultra-aggressive race-style clutch setup.

Driving Feel

A lightweight flywheel reduces rotating mass at the engine, allowing the engine to gain and lose RPM more quickly. The result is a sharper, more immediate connection between your right foot, the engine, and the gearbox. Rev-matched downshifts feel cleaner, throttle blips feel more natural, and the car takes on a more responsive, motorsport-style personality.

Because the flywheel is lighter than the factory flywheel setup, some additional drivetrain noise, gear rollover sound, or chatter may be present. This is normal for many lightweight flywheel conversions and is part of the more mechanical driving experience.

The best way to minimize NVH and gearbox chatter is to avoid lugging the engine. Drivers should never lug the engine to begin with, and this is especially important with a lightweight flywheel. Keeping the engine above approximately 2,000 rpm, or selecting a lower gear when climbing hills or accelerating from low speed, will help keep the drivetrain happier and reduce unwanted chatter. The higher the rpm, the less drivetrain chatter and NVH you will have.

Which Version Should I Buy?

AASCO offers several lightweight flywheel and clutch options across the Porsche 911 platform. The correct choice depends on your chassis, engine, transmission, and clutch package.

This listing is for the AASCO 106443-12 flywheel only. It is the right choice if your compatible Porsche 991.2 manual application uses the OE twin plate clutch setup and you only need the lightweight steel flywheel.

OE Twin Plate Clutch Compatibility

This flywheel is designed for use with the OE twin plate clutch on compatible Porsche 991.2 applications listed by AASCO.

Do not assume this flywheel is correct for every 991.2 model. Fitment depends on the exact model, engine, transmission, and clutch configuration.

Flywheel-Only vs. Complete Package

Choose this 106443-12 flywheel-only listing if your car already has a compatible OE twin plate clutch setup in good condition, or if you are replacing an existing AASCO 106443-12 flywheel and reusing compatible clutch components.

If your clutch is worn, your pressure plate is worn or unknown, or you want a complete flywheel and clutch package, the associated complete package is 406453-12-TIL-PKG.

The 406453-12-TIL-PKG package should be used only where the complete Tilton twin plate clutch package is confirmed to be compatible with the exact vehicle. If you are unsure, contact us before ordering so we can help verify the correct AASCO option for your car.

Good Candidates for This Flywheel-Only Listing

This flywheel-only listing is generally intended for:

  • Select Porsche 991.2 Carrera 3.0L turbocharged manual applications listed by AASCO

  • Select Porsche 991.2 Carrera S 3.0L turbocharged manual applications listed by AASCO

  • Select Porsche 991.2 Carrera T 3.0L turbocharged manual applications listed by AASCO

  • Select Porsche 991.2 Carrera GTS 3.0L turbocharged manual applications listed by AASCO

  • Select Porsche 991.2 GT3 4.0L manual applications listed by AASCO

  • Cars using the OE twin plate clutch setup

  • Cars that already have a compatible clutch and pressure plate setup in good condition

  • Cars replacing an existing AASCO 106443-12 flywheel

  • Drivers who want the lightweight flywheel only rather than a complete clutch package

If you are unsure which version you need, contact us with your year, model, engine, transmission, and current clutch setup so we can help point you toward the correct AASCO option.
