As the title states. I am torn. Yes I have searched around a bit. Both weigh round 12 lbs... Can't find any good info. Only exedy stage 1 with an act or exedy not vice versa. Btw Exedy part number mF04.

 

i have a streetlite flywheel with my act hd pp/exedy organic disc combo, the streetlite is about the some weight as stock. i dont notice any different, but you should also get ss clutch lines and do the slave cylinder pill delete for the full effect

 

Thanks.for the reply. the ss and pill removal is already done.. I have heard a bit of ppl with the exedy clutch and act flywheel. . Just wondering why one was better than the other. Anyone vouching for act or exedy

 

flywheel really doesnt matter as long as its single chromoloy, multi plated flywheels tend to break at higher revolutions.

 

That makes sense also I won't be shifting over 7300.. I just know exedy has holes in it multiplate like you are saying and they claim better heat removal...Didn't know if that made a difference. As far warped/cooling goes.

 

exedy makes a single chromoly flywheel, weighs 13.5lbs i believe

 

Both the ACT and Exedy flywheels are one piece (integral ring gear). I can't speak for the Exedy flywheel design, but I can tell you about the ACT flywheels. ACT flywheels are forged chromemoly, heat treated for toughness (not too hard) but the ring gear is induction hardened for long gear life. They are SFI certified and legal for NHRA competition and are spin balanced within .25 oz in.

The Streetlite is about the same weight as stock (13.5 pounds) but much thicker behind the clutch surface for better heat tolerance (stock flywheel is pretty thin), with additional material taken away around the outside perimeter instead. Honestly you may not notice any difference except in durability such as what is needed for drag racing, etc.

The Prolite is just under 10 pounds with even more material taken away from the outside perimeter (where it counts the most) and yet still thicker than stock behind the clutch surface. Since the stock flywheel is already light, you will only notice a modest improvement in engine response that is not too difficult to drive or hard to get used to IMO.
