AASCO Fitment Guide

Upgrade your manual Porsche 997 Carrera with an AASCO lightweight steel flywheel designed to reduce rotating mass and improve engine response. This approximately 20 lb lightweight steel flywheel replaces the heavier factory dual-mass flywheel setup on compatible Porsche 997 Carrera models, helping the engine rev more freely, respond more sharply, and feel more alive during downshifts, heel-toe shifting, and spirited driving.

Compared to the approximately 32 lb factory flywheel setup, this AASCO lightweight steel flywheel removes about 12 lb of rotating mass from the engine. The result is a sharper, more responsive flat-six that feels more eager and more connected without moving to the lightest possible flywheel option.

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 997 Carrera 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 flywheel is a great choice for drivers looking for a more responsive, motorsport-inspired feel from their manual 997 Carrera while staying with a lightweight steel flywheel design. Steel can be a nice balance for street-driven cars that want sharper response and improved rev-matching feel without going to the most aggressive lightweight flywheel setup available.

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 significantly lighter than the factory dual-mass 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 106437-12 lightweight steel flywheel only. It is the right choice if your car already has a compatible clutch and pressure plate setup in good condition, or if you are specifically replacing only the flywheel.

Steel vs. Aluminum Lightweight Flywheel

AASCO offers both aluminum and steel lightweight flywheel options for many Porsche applications.

The lightweight steel flywheel is a good choice for drivers who want sharper response than the factory dual-mass flywheel while retaining a slightly more street-balanced setup than the lightest aluminum flywheel option.

The aluminum flywheel option is generally the more aggressive lightweight choice and may provide the quickest engine response, while the steel flywheel can offer a nice middle ground for street and performance use.

Complete Kit vs. Flywheel-Only

This is a flywheel-only listing. Clutch components, pressure plate, release bearing, and related installation hardware are not included.

Choose this 106437-12 flywheel-only option if:

• Your existing clutch and pressure plate setup is compatible and in good condition

• You are specifically replacing only the flywheel

• Your release bearing and related clutch hardware are already being handled separately

• You already know which clutch and pressure plate setup will be used with the flywheel

Choose the complete AASCO lightweight steel flywheel and Sachs Performance clutch kit instead if:

• Your clutch is worn or due for replacement

• Your pressure plate is worn, heat-spotted, damaged, or unknown

• Your release bearing or related hardware needs replacement

• You want everything matched together as a complete AASCO / Sachs package

• You are unsure what clutch and pressure plate setup is currently installed

For the complete flywheel and clutch package, use AASCO part number 106437-12-PKG.

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.

Installation Notes

AASCO Fitment Guide

Upgrade your manual Porsche 997 Turbo, 997 GT3, or 997 GT3 RS with a complete AASCO billet aluminum lightweight flywheel and Sachs Performance clutch package designed to reduce rotating mass, dramatically improve engine response, and refresh the clutch system at the same time. This kit pairs the AASCO 13.6 lb lightweight flywheel with compatible Sachs Performance clutch components for select Porsche 997 Turbo, GT3, and GT3 RS manual applications.

Compared to the heavier factory 30 lb dual-mass flywheel setup, the AASCO lightweight flywheel removes roughly 16.4 lb of rotating mass compared to the factory flywheel. The result is an engine that revs more freely, responds more sharply, and feels more alive during downshifts, heel-toe shifting, and spirited driving.

At DasMotoring, this is one of our favorite upgrades for a manual Porsche.

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 significantly lighter than stock, some additional drivetrain noise, gear rollover sound, or chatter may be present compared to the factory dual-mass flywheel setup. 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 similar-looking lightweight flywheel and clutch kit options for the 996 / 997 Carrera platform. The correct kit depends on the model, model year, and pressure plate configuration.

This listing is for the AASCO 106411-11-PKG-02-04 complete kit. It is the right choice if you want the AASCO lightweight flywheel, Sachs Performance pressure plate, Sachs clutch disc, release bearing, and hardware together as a matched package for your 2005–2008 Porsche 997 Carrera S / Carrera 4S 3.8L manual.

How This Differs From 106411-11-PKG

The 106411-11-PKG and 106411-11-PKG-02-04 kits use the same AASCO lightweight flywheel and the same Sachs clutch disc. The key difference is the Sachs Performance pressure plate included in the kit.

• 106411-11-PKG uses Sachs Performance pressure plate 883082999736

• 106411-11-PKG-02-04 uses Sachs Performance pressure plate 883082999754

The flywheel is the same. The clutch disc is the same. The pressure plate is what changes, which is why these kits are separated by model, model year, and clutch configuration.

For 2005–2008 Porsche 997 Carrera / Carrera 4 non-S applications, use 106411-11-PKG.

For 2005–2008 Porsche 997 Carrera S / Carrera 4S 3.8L applications using the Sachs Performance clutch / pressure plate setup, use 106411-11-PKG-02-04.

For 2002–2004 Porsche 996 Carrera / Carrera 4 / Carrera 4S applications, use 106411-11-PKG-02-04.

For 1999–2001 Porsche 996 Carrera / Carrera 4 applications, use 106411-11-PKG.

Good Candidates for This Complete Kit

This complete kit is generally intended for:

• 2005–2008 Porsche 997 Carrera S / Carrera 4S 3.8L manual applications listed by AASCO

• Cars converting to the included Sachs Performance clutch / pressure plate setup

• Cars with a worn clutch, worn pressure plate, or unknown clutch service history

• Cars converting from the factory dual-mass flywheel setup to an AASCO lightweight flywheel and Sachs Performance clutch setup

• Drivers who want everything matched together as a complete AASCO / Sachs package

Flywheel-Only vs. Complete Kit

Choose the 106411-11 flywheel-only listing if your car already has a compatible clutch and pressure plate setup in good condition, or if you are replacing an existing AASCO 106411-11 flywheel and reusing compatible clutch components.

Choose this 106411-11-PKG-02-04 complete kit if your clutch is due for replacement, your pressure plate is worn or unknown, or you want the flywheel and clutch components matched together from the start.

If your 997.1 Carrera S / Carrera 4S is retaining the factory OEM pressure plate, AASCO lists the flywheel-only option as 106417-11.

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.

Service Parts

• Replaceable friction surface: HS9587T-POR

• Friction surface bolt package: HS9587T-POR-BLT-PKG

Installation Notes

AASCO notes that the larger portion of the clutch disc spring carrier must face toward the flywheel. If the clutch disc is installed backwards, the clutch diaphragm spring may contact the clutch disc, which can result in clutch failure and may not be covered under warranty.

Professional installation is recommended. However, there are DIY how-to guides linked below if you have the tools and equipment at home.

Important Notes

This listing is for the complete AASCO lightweight flywheel and Sachs Performance clutch package listed under part number 106411-11-PKG-02-04.

Fitment may depend on the vehicle’s model year, engine, transmission, and clutch / pressure plate configuration. Always confirm compatibility with your exact vehicle before ordering.

Before installation, compare the new flywheel, clutch, pressure plate, release bearing, and hardware to the original components being replaced.
