AASCO Lightweight Flywheel & Sachs Performance Clutch Kit – Porsche 996 Turbo / GT3 Manual

Part Number: 106413-11-PKG
Brand: AASCO Motorsports

AASCO Fitment Guide

Upgrade your manual Porsche 996 Turbo, 996 GT3, or 996 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 996 Turbo, GT3, and GT3 RS manual applications.

On the 996 GT3, the factory flywheel is approximately 30 lb, meaning this AASCO 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. A lightweight flywheel can completely change the character of the car — making it feel sharper, more mechanical, and more connected. If your 996 Turbo, GT3, or GT3 RS 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 complete kit is a great choice for drivers looking for a more responsive, motorsport-inspired feel from their manual 996 Turbo, GT3, or GT3 RS while also replacing the clutch, pressure plate, release bearing, and related hardware with a matched Sachs Performance clutch package. The AASCO flywheel also uses 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

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 lightweight flywheel-only and complete flywheel / clutch package options for Porsche 996 Turbo, GT3, and GT3 RS applications. The correct choice depends on whether you need only the flywheel or whether you want to replace the clutch system at the same time.

This listing is for the AASCO 106413-11-PKG complete kit. It is the right choice if you want the AASCO lightweight flywheel, Sachs Performance pressure plate, Sachs Performance clutch disc, release bearing, and installation hardware together as a matched package for your compatible 996 Turbo, GT3, or GT3 RS manual.

How This Differs From 106413-11 Flywheel-Only

The 106413-11 listing is the 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 replacing an existing AASCO 106413-11 flywheel and reusing compatible clutch components.

This 106413-11-PKG listing is the complete kit. It is the better choice if your clutch is worn, your pressure plate is worn or unknown, or you want the flywheel and clutch components matched together from the start.

Good Candidates for This Complete Kit

This complete kit is generally intended for:

• Porsche 996 Turbo manual applications listed by AASCO

• Select Porsche 996 GT3 manual applications where this AASCO / Sachs clutch package is confirmed

• Select Porsche 996 GT3 RS manual applications where this AASCO / Sachs clutch package is confirmed

• 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

If you already have a compatible clutch and pressure plate setup in good condition and only need the flywheel, choose the 106413-11 flywheel-only listing instead.

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: HS9565

• Flywheel bolt kit / torque plate: BLT6413

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 106413-11-PKG.

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.
