AASCO Lightweight Flywheel for Porsche 996 Carrera Non-Turbo Manual 1999-2004

Part Number: 106411-11
Brand: AASCO Motorsports

AASCO Fitment Guide

Upgrade your manual Porsche 911 with an AASCO billet aluminum lightweight flywheel designed to reduce rotating mass and dramatically improve engine response. This 13 lb flywheel replaces the heavier factory 32 lb flywheel setup on compatible Porsche 996 and 997 Carrera models, 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 996 or 997 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 911 while retaining a proven AASCO flywheel design with a serviceable friction surface. With proper maintenance and normal use, the flywheel body is designed to be reused long-term — so future clutch services typically only require replacing the friction surface rather than the entire flywheel.

Fitment

Fits select manual transmission Porsche 911 models:

• 1999–2004 Porsche 911 Carrera / Carrera 4, 996 chassis, non-turbo

• 2005–2008 Porsche 911 Carrera / Carrera 4, 997 chassis, non-turbo

• 2005–2008 Porsche 911 Carrera S / Carrera 4S, 997 chassis, 3.8L, depending on clutch and pressure plate configuration (see below)

Porsche 997 Carrera S / 4S applications may require confirmation of the clutch and pressure plate setup before purchase. This flywheel is not intended for Turbo or GT3 applications unless specifically confirmed.

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 options for the 996 / 997 Carrera platform, and the correct part depends on your model and clutch / pressure plate setup.

This listing is for the AASCO 106411-11 flywheel only. It is the right choice if your car already has a compatible clutch and pressure plate setup, or if you are replacing an existing AASCO 106411-11 flywheel and reusing compatible clutch components.

Good Candidates for This Flywheel-Only Listing

This flywheel-only listing is generally intended for:

• 1999–2004 Porsche 996 Carrera / Carrera 4 non-turbo manual applications listed by AASCO

• 2005–2008 Porsche 997 Carrera / Carrera 4 non-turbo manual applications listed by AASCO

• 2005–2008 Porsche 997 Carrera S / Carrera 4S cars that already have a compatible Sachs Performance clutch / pressure plate setup

• Cars replacing an existing AASCO 106411-11 flywheel

Factory Pressure Plate vs. Sachs Performance Pressure Plate

For many 996 / 997 Carrera non-turbo applications, this flywheel can be used as the flywheel-only option when the existing clutch and pressure plate setup is compatible and in good condition.

For 2005–2008 Porsche 997.1 Carrera S / Carrera 4S 3.8L applications, the correct AASCO option depends on the pressure plate configuration:

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

• If your 997.1 Carrera S / Carrera 4S is using, or being converted to, the Sachs Performance clutch / pressure plate setup, AASCO lists the complete kit as 106411-11-02-04-PKG.

When to Buy the Complete Kit Instead:

Choose a complete AASCO flywheel and clutch kit instead of this flywheel-only listing if:

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

• You are converting to the Sachs Performance clutch setup

• You have a 997 Carrera S / Carrera 4S and are not sure which pressure plate is currently installed

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

For 997.1 Carrera S / Carrera 4S models, we strongly recommend confirming the current clutch and pressure plate setup before ordering. If you are unsure, 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

Important Notes

This listing is for the flywheel only. Clutch components, pressure plate, release bearing, hardware, and related installation parts are not included unless specifically stated.

For 997 Carrera S / 4S models, fitment may depend on whether the vehicle is using the factory pressure plate, Sachs Performance clutch components, or another clutch configuration. Always confirm compatibility with your exact model, year, engine, transmission, and clutch setup before ordering.

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