AASCO Lightweight Flywheel – Porsche 997 Turbo / GT3 / GT3 RS Manual
Part Number: 106413-11
Brand: AASCO Motorsports
Upgrade your manual Porsche 997 Turbo, 997 GT3, or 997 GT3 RS with an AASCO billet aluminum lightweight flywheel designed to reduce rotating mass and dramatically improve engine response. This 13.6 lb flywheel replaces the heavier factory 30 lb dual-mass flywheel setup on compatible Porsche 997 Turbo, GT3, and GT3 RS models, removing roughly 16.4 lb of rotating mass. 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 997 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 is a great choice for drivers looking for a more responsive, motorsport-inspired feel from their manual 997 Turbo, GT3, or GT3 RS 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.

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 similar-looking lightweight flywheel and clutch options for Porsche 996 / 997 Turbo, GT3, and GT3 RS applications. The correct choice depends on whether you need the flywheel only or a complete flywheel and clutch package.
This listing is for the AASCO 106413-11 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.
Good Candidates for This Flywheel-Only Listing
This flywheel-only listing is generally intended for:
Porsche 997 Turbo manual applications listed by AASCO
Porsche 997 GT3 manual applications listed by AASCO
Porsche 997 GT3 RS manual applications listed by AASCO
Cars that already have a compatible clutch and pressure plate setup
Cars replacing an existing AASCO 106413-11 flywheel
Drivers who want the lightweight flywheel only rather than a complete clutch package
When to Buy the Complete Kit Instead
Choose a complete AASCO flywheel and Sachs Performance clutch kit instead of this flywheel-only listing if:
Your clutch is worn or due for replacement
Your pressure plate is worn, heat-spotted, damaged, or unknown
You are converting from the factory dual-mass flywheel setup to a complete AASCO / Sachs clutch package
You want everything matched together as a complete flywheel, clutch, pressure plate, release bearing, and hardware package
For 997 Turbo / GT3 / GT3 RS applications, AASCO also lists the complete kit option as 106413-11-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.
Service Parts
Replaceable friction surface: HS9565
Flywheel bolt kit / torque plate: BLT6413
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.
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.
Professional installation is recommended. However, there are DIY how-to guides linked below if you have the tools and equipment at home.
Before installation, compare the new flywheel and related components to the original components being replaced.
Availability
AASCO Motorsports parts are specialty performance components. Although many items are available from stock, occasional delays may occur if an item is backordered or if AASCO is manufacturing a new batch. If there is a delay, we will provide an updated ETA before fulfillment.
