XTD CLUTCH CHROMOLY LIGHT-WEIGHT FLYWHEEL COMPATIBLE WITH INTEGRA CIVIC SI B16 B17 B18 B20

🔧 B Series Lightweight Flywheel XTD Honda Acura – Key Features

• Lightweight Chromoly Steel Construction – Strong, durable, and significantly lighter than OEM
• Faster Engine Response – Quicker revving and improved acceleration feel
• Reduced Rotational Mass – Less drag on the engine = more usable performance
• Precision Balanced – Smooth operation even at high RPM
• Street & Performance Ready – Perfect for daily drivers and weekend builds

XTD Flywheels are made using the highest quality, most modern materials available (Flywheel weight:10LBS). XTD could achieve manufacturing its original flywheels about 200% more strength compared with normal flywheels. It was forged using Chrome-molybdenum steel.

🚗 Vehicle Fitment

Honda / Acura B-Series Engines

• B16
• B17
• B18
• B20

Common Applications:

• Acura Integra
• Honda Civic Si
• Civic Del Sol VTEC
• CR-V (B20 swaps/builds)

(If it’s B-series and manual, this is your lane.)

The power of inertia rotation can be decreased by reducing the excess weight, and therefore, its strength directly passed through to the high response. The XTD light weight flywheel is made from the optimal weight and optimal form which were set up for each type of a car from the chrome forge material. By shaving all circumference of the chrome forge material, the variation in weight and the deviation of balance are pressed down to the minimum.

💡 Why Go Lightweight?

Stock flywheels are heavy for comfort—not performance.

Switching to a lightweight flywheel gives you:

• Faster revving engine
• Sharper throttle response
• Quicker gear changes
• More engaging driving feel

Trade-offs (because we’re honest here):

• Slightly rougher idle
• Easier to stall if you drive like it’s stock
• Less “daily smooth,” more “driver-focused”

Processing for raising wear durability and heat treatment etc… is performed in the surface. Various know-how for realizing lightness, strength, and high balance is condensed to the XTD light weight flywheel. If a flywheel is made light, it is said that an engine response improves.

⚙️ Installation Notes

• Direct bolt-on for B-series manual transmissions
• Best paired with upgraded clutch kits
• No tuning required—but you’ll feel it immediately

In case of revolving thing like a flywheel, the power (inertia power) which is always going to continue fixed rotation occurs. When an accelerator is stepped on in from an idling state, a flywheel tends to keep an idling state according to its inertia power, although engine is going to raise rotations. When inertia power becomes large, much time is needed for going up rotation. In the case of the XTD lightweight flywheel, since weight (especially flywheel perimeter part) is light, there is little inertia power of influencing rotation of engine.
