actually both the fidanza and the clutchmasters flywheel are the same, both made by fidanza... they are made out of aluminum, and weigh about 8 pounds (dont know the exact weight)...

i know many people that have opted for the fidanza with excellent results, furthermore, i have never heard of a fidanza flywheel breaking on a prelude...

i would definetely not recommend you shave your stock flywheel...

don't get a chromoly one, those are pretty much for straight up race applications. they are bad on your starter motor teeth and they're pretty brittle so they're prone to crack and explode and sever brake lines or steering connections or something terrible like that. go with the CM one

since i own a jun chromoly flywheel, i felt obligated to respond... the jun fw are certainly not for race only applications... jun offers both a 13 lb and an 11 lb fw, both of which are very streetable, much more so than a fidanza or a clutchmasters...

ive had my jun in the car for over a year now, absolutely no problems with my starter... to the best of my knowledge, it was only gsr's that had the problem with the light (not the ultralight) jun... even if there was a problem with the starter, the teeth on the starter can be shaved to make a good match with the fw... this should eliminate the problem...

even though im sure the possibility is there, i have never, ever heard of a jun flywheel exploding or cracking... on the other hand, i know of two cracked clutchmaster fw... a good buddy of mine that is a mechanic at a shop, has pictures, i will post as soon as i can get my hands on them...

I got the ACT one , either way 15lbs is too light. You should only drop maybe 15% of the weight.

Also note some drag-cars actually add weight to the flywheel. Only high rpm course racing will really benefit.....in stop and go situations the youll find it a bitch to get moving....it also makes it hard to get a proper launch at the 1/4 mile....as well as messes with driveability. Youll find rev-matching is a lot harder , revs drop real fast......and im pretty sure driving uphill with a lightweight flywheel is worse on acceleration......

that is exactly why i didnt go with a fidanza... since the car is primarily a stip car, having a fw that is too light can hurt your launches...

my jun feels almost stock-like... the engine revs up easier, but other than that, i notice no other side-effects... revs dont drop any faster, no problems at stoplights or uphills, the only reason stop and go traffic might have been a bit more difficult for me at first is that i have a 6 puck metallic clutch...

btw, just so that everybody knows, act stopped making flywheels a while back... actually, they were lightened oem...

not that i dont believe you but aluminum doesnt crack it bends.. chromoly on the other hand does crack...

i believe more in the aluminum flywheels but that is just me.. there are various pros and cons to both...

just because aluminum is a softer material than chromoly doesnt mean that it wont crack...

regardless, i believe both fidanza and jun make exellent flywheels... its just a question of how light you want to go...
