AASCO Lightweight Steel Flywheel – Porsche 997.2 Turbo Manual 2010-2013

Part Number: 106430-12
Brand: AASCO Motorsports

AASCO Fitment Guide

Upgrade your manual Porsche 997.2 Turbo with an AASCO lightweight steel flywheel designed to reduce rotating mass and dramatically improve engine response. This 22 lb lightweight steel flywheel replaces the heavier factory 30 lb dual-mass flywheel setup on compatible Porsche 997.2 Turbo DFI manual applications with the 10-bolt crank, removing approximately 8 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 997.2 Turbo 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 997.2 Turbo while retaining a flywheel-only setup. The AASCO flywheel is a lightweight steel design, which can be a nice balance for street-driven cars that want sharper response without going to the lightest possible flywheel 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 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 Turbo applications. The correct choice depends on your chassis, engine, crankshaft configuration, and whether you need only the flywheel or a complete clutch package.

This listing is for the AASCO 106430-12 flywheel only. It is the right choice if you have a compatible 997.2 Turbo DFI manual application and only need the lightweight steel flywheel.

How This Differs From 106413-11

The 106413-11 flywheel is used for earlier 996 / 997 Turbo and GT3 applications, including 997.1 Turbo applications.

The 106430-12 flywheel is for later 997.2 Turbo DFI applications with the 3.8L Turbo engine and 10-bolt crank.

Do not assume the earlier 106413-11 flywheel is correct for a 997.2 Turbo DFI car. For compatible 997.2 Turbo DFI applications with the 10-bolt crank, use 106430-12.

Flywheel-Only vs. Complete Kit

Choose this 106430-12 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 106430-12 flywheel and reusing compatible clutch components.

Choose the complete 106430-12-PKG kit instead if:

• Your clutch is worn or due for replacement

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

• You want the flywheel, Sachs Performance pressure plate, Sachs Performance clutch disc, release bearing, and installation hardware matched together as a complete package

Good Candidates for This Flywheel-Only Listing

This flywheel-only listing is generally intended for:

• Porsche 997.2 Turbo 3.8L DFI manual applications listed by AASCO

• Compatible 997.2 Turbo manual cars with the 10-bolt crank

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

• Cars replacing an existing AASCO 106430-12 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, crankshaft configuration, and current clutch setup so we can help point you toward the correct AASCO option.

Installation Notes

The AASCO listing notes that this is a 10-bolt crank application and that it must use 991 non-turbo flywheel bolts.

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 AASCO lightweight steel flywheel listed under part number 106430-12. Clutch disc, pressure plate, release bearing, flywheel bolts, and related installation parts are not included unless specifically stated.

This flywheel is specifically for compatible 997.2 Turbo DFI manual applications with the 10-bolt crank. Fitment may depend on the vehicle’s model year, engine, transmission, crankshaft configuration, and clutch / pressure plate setup. Always confirm compatibility with your exact vehicle before ordering.

Before installation, compare the new flywheel and related components to the original components being replaced.
