It's that dreaded time. my OEM clutch is on its way out. :(
I want to upgrade to the Competition Clutch stage 1.5. Kseriesparts sells them packaged with either the light weight or ultra lightweight flywheel. Since its only like $20 difference I was thinking of getting the ultra lightweight. So my question is are there any disadvantages to the ultra lightweight? Any reason someone wouldn't like it or to stay away from it? My car is primarily a DD with just suspension work done. Thanks in advance for any help! :)

No disadvantages? That's a personal opinion I think.

In general, lighter flywheel equals rpms climb and drop faster which leads to quicker response etc. So your rpms will drop off much faster during your shifts. I also believe it affects the momentum of your car. Then you can get into inertia, force, mass etc etc etc. Heard super/ultra lightweight flywheels can suck in stop and go traffic or traffic jams. Personally I'd go with a 12lb if/when I had to redo my clutch/flywheel. Not terribly light or heavy.

all motor you'll be fine running a lightened flywheel, but for boost go with one that has some weight to it

The DC5 Type-R OEM Honda flywheel weights 11lbs. The Type-S RSX flywheel weighs 14lbs. As you can see the Type-R flywheel is 3lbs lighter, and if it affected driveability I doubt Honda would have included it into the Type-R. It will increase throttle response as the RPM's will rise slighty quicker. The downside is that most ultra light flywheels are aluminum and tend to wear quicker than OEM steel.

The driveability issues come with pairing ultra light flywheels (8lbs) with high torque capacity clutches (Stage3+) as it becomes harder to match RMP's unless your at WOT.

My opinion, there is no reason to back to stock flywheel and there is also no reason to go any lighter than 11lbs unless your planning to track.

Had the Exedy 8.5lb. You'll have to slip the clutch a lot more at higher revs to get the car moving -- this is a pain in traffic and in parking lots. Eventually got sick of it and went back to stock.

Only major con that I came across with a lightweight flywheel is when you couple is with a harsh engagement style clutch (Competition Clutch Stage 4) you will get transmission chatter when trying to feather the clutch. VERY annoying when your car is a DD and trying to go through a drive through or stop and go traffic. This is the main reason I switched from the CC Stage 4 clutch...but either way...be warned that a lightweight flywheel (anything less than 11lbs) will probably result in a car the isn't much fun for a DD. Im assuming you are planning on using yours as a DD but if not...the "racing" improvements with a lightweight flywheel are very nice.

Enjoy.

CC 1.5 clutch and lightweight flywheel is an awesome combo. I opted for the lightweight instead of the ultra-lightweight and have no regrets. Motor revs up quick and rev drop between shifts doesn't cause any harsh engagements.

IIRC I read on the CC website that the ultra-lightweight was designed with boost in mind where as the lightweight one is better for NA applications.
