Do your think you would feel a decent ammount of differnece if you go with a jun or toda flywheel opposed to a comptech or fidenza... jus asking becuase the price is alot more for toda or jun

 

You probably won't notice a huge difference between any of them, although the Comptech and Fidanza are actually the two lighter units (and are also "USDM" and as such have never displayed the starter grinding that certain JDM units have when installed on US cars).

Toda proponents often bring up the valid point that overall weight isn't the only factor that affects how a flywheel "feels", and that the distribution of the flywheel's mass (i.e., centralized vs. towards the outer edges) plays an important part as well. That being said, while Toda touts that their unit is built with this weight-centralization in mind, to the best of my knowledge there hasn't been any testing or evidence to prove/disprove this claim, or to indicate that the other, lighter flywheels don't also have this "favorable" sort of distribution.

Of course, there is then the entirely different considerations of chromoly vs. aluminum, replaceable friction surfaces, etc.

I think it would be great to see some sort of flywheel test put together, where various offerings are weighed, and their rotational inertias are somehow evaluated.

 

my buddy has a clutch master flywheel and stage 1 clutch on i/h/e mods and it feels great not a problem. He loves it. I went with same flywheel and stage 3 but i'm going turbo and can't tell u how that feels yet.

 

Just just rebuilt my Engine and still breaking it in so I have not been able to test my clutch and FW setup but I selected the J's Racing 3.9kg FW with a Spoon Clutch Disk and pressureplate.
The Spoon pressureplate is noticeably heavier (not meaning in weight but grab) Spoon claims 30% more but it's really hard to gage at this point.
The J's FW is fine but a little light for my taste. It does idel very smoothe and no surges or pulsing. I think is would be perfect for me if it were say arounf 4.1kg
In response to the weight distribution comment. This is exactly true. if you notice the design of the TODA, JUN and the J'S FW you see that twars the edge there are large holes most if not all of these FW are constructed of Leightweight Cromoly. Weight distribution is as important if not more important than the over all weight itself.
One other Mod I was able to test was the slave hose from SPoon. This made for a more exact pedal response for the clutch and seemingly better control when feathering the clutch. I do think this will be a modification that I include to my setup
