AASCO Fitment Guide

Upgrade your manual Porsche 992 Carrera with a complete AASCO lightweight steel flywheel and Tilton ST-215 twin plate clutch package designed to reduce rotating mass, increase clutch holding capacity, and dramatically improve engine response. This package pairs the AASCO 106443-12 lightweight steel flywheel with a Tilton ST-215 2-plate sprung organic clutch package rated for approximately 600 lb-ft of torque.

Compared to the factory flywheel and clutch setup, this AASCO / Tilton package gives the car a sharper, more motorsport-inspired feel while still using a sprung organic clutch configuration. The result is a more responsive engine that revs more freely, responds more directly, 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 992 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 complete package is a great choice for drivers looking for a more responsive, higher-capacity clutch and flywheel setup for their manual 992 Carrera-family 911. The Tilton ST-215 twin plate clutch package provides more holding capacity than a typical factory-style clutch setup, while the sprung organic disc configuration helps keep it more street-friendly than an aggressive unsprung race clutch.

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 this package replaces the factory-style flywheel and clutch setup with a lighter flywheel and twin plate clutch package, some additional drivetrain noise, gear rollover sound, or chatter may be present. This is normal for many lightweight flywheel and performance clutch 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, clutch setup, and power level.

This listing is for the AASCO 406453-12-TIL-PKG complete package. It is the right choice if you want the AASCO 106443-12 lightweight steel flywheel and Tilton ST-215 twin plate sprung organic clutch package together as a matched setup for your compatible 992 manual 911.

How This Differs From 106443-12

The 106443-12 listing is the flywheel-only option for select Porsche 991.2 / 992 manual applications using the OE twin plate clutch setup.

The 406453-12-TIL-PKG listing is the complete Tilton twin plate clutch package. It includes the AASCO 106443-12 lightweight steel flywheel along with the Tilton ST-215 2-plate sprung organic clutch package.

Choose 106443-12 if your car already has a compatible OE twin plate clutch setup in good condition and you only need the flywheel.

Choose 406453-12-TIL-PKG if your clutch is worn, your pressure plate is worn or unknown, you need additional torque capacity, or you want the flywheel and Tilton twin plate clutch components matched together from the start.

OE Twin Plate vs. Tilton ST-215 Package

The 106443-12 flywheel-only listing is designed around the OE twin plate clutch setup.

This 406453-12-TIL-PKG package is a more complete clutch and flywheel solution using the Tilton ST-215 twin plate sprung organic clutch package. It is a better fit for customers who want a higher-capacity clutch package rather than simply replacing the flywheel while retaining the factory clutch configuration.

Good Candidates for This Complete Package

This complete package is generally intended for:

• Select Porsche 992 Carrera S 3.0L twin-turbo manual applications where confirmed

• Select Porsche 992 Carrera 4S 3.0L twin-turbo manual applications where confirmed

• Select Porsche 992 Carrera GTS 3.0L twin-turbo manual applications where confirmed

• Select Porsche 992 Carrera 4 GTS 3.0L twin-turbo manual applications where confirmed

• Select Porsche 992 Carrera T 3.0L twin-turbo manual applications where confirmed

• Cars needing additional clutch holding capacity

• Cars converting from the factory clutch setup to a complete AASCO lightweight steel flywheel and Tilton ST-215 twin plate clutch package

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

If you already have a compatible OE twin plate clutch setup in good condition and only need the flywheel, choose the 106443-12 flywheel-only listing instead.
