PRODUCT DETAILS
Competition Clutch 2 694D ST Ultra Lightweight Steel Flywheel is a direct replacement flywheel for 1990 to 2005 Civic D series setups. If you’re shopping a 90-05 Civic Race Flywheel, this is the no nonsense version, one piece 4140 forged steel, built to take abuse. The flywheel bolts to your crank, gives your clutch disc its friction surface, and sets a big part of how fast your D15, D16, or D17 snaps up and down in rpm.
Your factory flywheel stays heavy because Honda wanted smooth launches, stable idle, and fewer stalls. This Civic 90-05 Lightweight Flywheel drops a lot of that rotating mass. At Civic Flywheel 8.8 lbs, it’s an Ultra Lightweight Civic Flywheel, so you’ll feel the engine rev quicker and drop rpm quicker too. That’s the trade. If you short shift or you live in stop and go traffic, you might notice it wants a little more attention off idle. If you drive it like you mean it, it feels sharper everywhere.
Competition Clutch lists this as a Civic 4140 Steel Flywheel with a one piece design. They also call out why that matters, they aim to reduce ring gear separation and friction surface warpage versus multi piece styles. You can also treat it like a normal service part, since it supports resurfacing during clutch jobs, which matters if you ever need a Honda Civic Resurfaced Flywheel instead of tossing it.

Selection notes for experienced installers
Competition Clutch splits these into lightweight and ultra lightweight for a reason. This Competition Clutch Civic Flywheel sits in their ultra lightweight steel category, and they recommend it for boost and competition use. Think Forced Induction Civic Flywheel, Track Racing Civic Flywheel, or a Civic Flywheel for Rally Racing, especially if you’re running a Civic Flywheel Performance Clutch combo like Civic Flywheel Stage 3 or higher. If your car stays mostly naturally aspirated and street driven, their standard lightweight steel option usually keeps low speed drivability happier. Pick based on how you actually use your car, not on what sounds cool on a forum.
Also worth saying out loud, this isn’t the ideal choice if you’re trying to make a tired commuter feel smoother. It’s for response and durability under hard use. We run these exact parts on our own cars because the faster rev match and quicker rpm recovery between corners feels right on a D Series Racing Flywheel setup.
Installation and setup considerations
You’ll pull the trans, same as any clutch job. If you resurface it, you must keep the correct flywheel step for the clutch you install. That matters a lot for engagement height and release, especially when you mix and match. Confirm your engine and transmission combo before you wrench, and confirm the part number before you order. If you need a Civic Flywheel for Stock Clutch, make sure your clutch choice and intended use line up, because ultra light parts can feel touchier at low rpm even when everything fits.
