28lb. or 18lb. Flywheel?
Getting ready to pull the trigger on a new clutch setup for my 2000 C5. I plan on going with the stage 1 setup from Monster Clutches. I plan on ordering from Tick Performance. When ordering, they give you an option of either a 28lb. flywheel or an 18lb. flywheel. The stock GM flywheel is around 28 or 29lbs. so going with the 18lb. flywheel is 10lbs. lighter than stock. I understand all of the basics about WHY you would want to do this from a track and racing standpoint but what I would like to know is WHAT (if any) adverse affects will there be in going with the 18lb. flywheel from a daily driver standpoint. Will it affect the idle in any way? If I go with a cam in the future, will it be difficult to make the thing idle properly? Will it take more throttle for clutch engagement from a full stop to get the car moving due to the decreased inertia from the flywheel? Will the downshifts be more agressive? If so; how much more aggresive? My C5 is more of a daily driver for me. Although I love to mod it I am one of those people who also would like to stay practical so that it remains comfortable to drive. In general, is there any REAL advantage to lightening up the flywheel? Talk to me....

I daily drive my 18lb Monster lightweight flywheel. I love it. I was really impressed because I really did not have to change driving styles at all, I usually just roll out of the clutch with a tiny blip of the throttle to get going. All you need.
For daily driver concerns, there are no CONS that come to mind for this flywheel. It's great. No issues in tuning, no idle adjustments, no aggressive shifts, you don't need a ton of gas to get it goin like everyone says.
I felt a difference in high RPM wide open runs on mine.

4 replies so far. On other forums my question would sit for days with no one answering. These seem like intelligent comments that are based on experience and experimenting. I am new to this forum so this is encouraging to me. I think I will stick around for awhile. i DID go ahead and order the Stage 2 Monster setup from Tick Performance today. However; at the last minute I opted to just stick with the 28lb flywheel for now.

I did have an 18lb fly & it was great, the engine (throttle, revs) felt way more responsive & never had any trouble with it.
4 yrs later while racing clutch starting slipping, when pulled out fly was warped, put that down to heat while slipping.
The heavier fly will disperse heat better. I am using a 28lb now & miss the free revving feeling.
My spare new clutch had the 28lb fly but when I had the fly, pressure plate & 6 puk plate balanced I had the fly lightened to 22lb.

Related question... I shattered my bellhousing when my stock rear end fell apart on the dyno. I'll be pulling the trans obviously and having the Monster stage 3 clutch inspected if it isn't apparent that it's smoked. It was on a Monster 18lb flywheel behind a 383 and soon the rear end will be a Strange S60 with 3.54 gears.
I picked up a 28lb Monster flywheel recently to swap in if the flywheel is damaged. With the 3.54 gears, is the 28lb more appropriate than the 18lb for daily driving duty? I'll have nitrous eventually and my torque curve is really fat with the 18lb, but I've kind of gathered that the 28lb would be better for me. Thanks in advance for input!

I recently installed a Monster stage 1 with the 18# flywheel, I got it from Tick Performance in there Tick/Monster complete clutch package and absolutely love it. It drives better than stock around town, and it grabs hard and shifts super easy when your running through the gears at WOT. I also weighed both my stock flywheel/disc/pressure plate assembly and my new monster set up, my stock setup weighed 50lbs, and my Monster clutch with 18# flywheel weighed 46lbs. So if you were to go with the 28# flywheel you'd end up with your clutch/pp assembly weighing 6lbs more than stock.

Id imagine less weight off the drivetrain would be a benefit. shesh saving 10lbs from replacing something thats already needed to be replaced is always a plus IMO. Driven civics with light weight flywheels and 6/4 puck unsprung clutches chatters a bit but its nothing to cry about.

No it's not!!
If your whole clutch assembly is 17lb, which I seriously doubt, it would only be good for racing..Trying to drive something on the street that's to light would only cause undue wear leading to clutch failure.

[QUOTE=HioSSilver;16180725]Well here it is. All 17# of it. You really don't know what your talkin about. Usually lasts about 2-3 years of dd-ing plus me beatin on it.
I stand corrected! Looks like a tripple race clutch though!
