LtWt Flywheel, Who's Runnin one?

Yeah, searching for RPS and Fidanza failures, they both come up, Fidanza more so, though. Still undecided, it seems there's at least a few failures for each

My concern with the Comp flywheels are, they seem to run quite a bit lighter than the others, 15-16lbs seems averaage which might be the magic weight? I DO like the idea of a once piece, less chance for failure of parts

It is 2 lbs heavier than the fidanza.

Here's the info I've gathered real quick:
Clutch Masters FW-622-AL 16 lbs aluminum
Clutch Masters FW-622-SF 16lbs steel
Competition 2-622-ST 14 lbs steel
Competition 2-622-STU 11.5 lbs steel
Fidanza 161301 12 lbs billet aluminum
SPEC SD03A aluminum no info
SPEC SM03S steel no info
RPS billet aluminum 12.5 lbs
stock 22lbs

Fidanza has been making these flywheels before RPS, so there might be a lot more Fidanza out there in the wild.

The Aluminum flywheels are literally half the mass of the stock flywheel, therefore it would heat up much much quicker than stock, thereby limiting the amount of launches you can do in a given time-frame. One benefit of the aluminum however, is that it cools down faster than steel.

I think it's pretty obvious that if you are making big power and drag racing then a steel flywheel would be a better option. On a BPU car cutting 1.7xx 60", I don't think there should be any problem unless you have a slipping clutch.... at least I never did.

This FS came on the FW when I bought it so I don't know the history.

It is obvious you are going to run this thing no matter what I say, so go for it.

Just to make it fair I was launching on slicks and prepped tracks which is probably equal to launching an AWD in most cases.

It looks like the issues come from hard launches which if you're doing a bunch of them a lightweight flywheel isn't ideal anyways.

Those are all good points. Anyone have an opinion on the Comp clutch flywheels? They're one piece steel, I've been doing just a general google search for reviews and the Fidanza definitely has more failures than any other, but like said, they've been around longer too. RPS had minimal search results and all the comp flywheel installs were on small cars with irrelevant information.

your car doesn't weigh 3800 lbs I hope.
