It's about that time ... I need a new clutch (Exedy Organic), so I figure I might as well add in a different flywheel (JUN Ultra Lightweight) and a Quaife LSD...

I've heard from some sources that JUN's flywheels are so thin that they cannot be resurfaced and they don't even last much more than 20K miles. Does anyone who races their car regularly have any experience with the flywheels? I'd rather just stick with the stock flywheel if the JUN flywheel is not going to last...

I dont know the answer to the durability of the JUN flywheel but dont u have a whole lot more in choices other than the JUN to choose from?

 

whatever flywheel you get, some have replacable friction plate, so it could last longer. and lighter --> better

 

What you've heard is bullshit.

I've had a JUN flywheel for about 50,000 miles now and it's in fine shape.

 

I'll probably get crucified 4 saying this but, I'm gonna go with Clutchmasters flywheel cuz it has a replacable contact surface & ring gear. Not saying Toda, Spoon or any other brand isn't any good, I just think the Clutchmasters F/W is good bang-4-buck. Plus it only weighs 9 lbs. I know cuz I sell them & have held them with my own hands & I'm very impressed with quality.

 

over 30,000 miles on mine and had no problems with it

 

JUN, SPOON and TODA are all made from Chromoly steel which is a whole lot more tougher than Aluminum, which is what the Clutch Master is made from. Just food for thought, look at metal density and durability on chromoly and you know what you heard is bullshit

 

Are these the ultra lite?

 

The only thing I would be concerned with the JUN flywheel is the starter teeth meshing problem. I don't know if it's been corrected though.

The JUN "ultra lightweight" flywheels are about 9.5 lbs. They aren't anything remarkably special in the weight department so look at all the other options you have too. It doesn't have to be JDM bling either to be good.

 

I have mine over 2 years and roughly over 60,000 miles. I've gone with 3 different clutches and yet not have a problem.

Other the start teeth gear skips once in awhile. It is a great investment.

 

The replaceable friction surface of the CM fly is steel, not aluminium.
