I haven't seen one out for the HR, but I've been told that they are not worth it and they cause a loss of torque. Then on the other hand I have been told that they are great and it would be very worth the money to invest in one. i want some input from a few of you out there...let me know.

 

I would consider getting an aftermarket clutch as well along with the flywheel. I would also get a stainless steel (SS) braided line to make it stiffer than stock. From what my friend told me and read here, the clutch will engage sooner, which means faster shifting.

 

i know all the above...i'm wanting to know if there is a power increase or responce increase that makes it a worth while or crappy mod? thanks for a reply tho.

 

Less rotating mass on the engine. Revs faster for matching downshifts, and gives you a bit more torque at the wheels in first and second. Starts to have a diminishing effect (as with all weight decreasing mods) the faster you're going.

 

Lightened flywheels make a VERY noticeable difference. The first thing you'll notice is that the engine will rev more easily and quickly. The car will accelerate faster through the gears as well. The nice part about a lightened flywheel is it gains power (well, i should say helps acceleration) throughout the entire powerband. It's just like dropping weight from the car. It helps acceleration from idle all the way to redline.

Lightened flywheels do no lose horsepower, they do not lose torque. A lightened flywheel will take a little more gas to get the car rolling from a stop, due to the fact that it stores less momentum than the heavier stock unit.


Edit: Also, I have a few lightened HR flywheels on order already and as soon as they arrive in, I'll be taking my car in for the slave cylinder recall.

 

On order from where? more info!!!

 

JWT should have their HR flywheels out in a month or so.

 

Oh shyt, thats good to know. Im guessing they won't have clutches to match?

 

they said that the clutch and their flywheel will go together on the 07 with no problem. thats what they told me this past friday

 

Oh yeh, Im sure the stock clutch would go fine with their flywheel, I was saying that Im guessing they wont have an aftermarket/upgraded clutch out to go with that flywheel. I really wouldn' t wanna flip for the labor cost of changing the flywheel and retaining the stock clutch. especially since its such a POS. lol. I wanna be able to launch at 5k and not fear that my clutch is gonna go bye bye it 10k miles or drop to the floor again.

 

no i meant their aftermarket clutch for the 03-06, he said the flyweel is what needed to be changed. i called him asking for a clutch and thats what he told me, if i get the flywheel that they have for the 07 then the clutch they sell will fit up to that

 

Yeah, their current clutch will fit the HR flywheels as well.

And I don't think it's the stock clutch that's the weak point, it's the slave cylinder/throwout bearing causing the issues. The older model stock clutches hold up to a LOT of abuse and the HR on paper is stronger too. With a good slave cylinder, the stock HR clutches should hold up to a lot of abuse too.

 

Is there any word if an aftermarket slave will be available. I know they have them for vette's, hoping we'll see something similar.

 

Has anyone done this or had success with the swap? I heard somewhere that aftermarket clutches would blow the slave cylinder

 

The 03-06 Fly's dont fit?

 

I haven't heard of it yet, but maybe I'm just not talking to the right people? I'll try it on my car and hope that it doesn't blow up.


Nope.

 

Does it make more sense to do both an aftermarket clutch and flywheel, or is the lightweight flywheel with the stock clutch sufficient?

 

If the info I heard was correct the only thing that should blow is the slave. but if you got the recall work with the updated slave maybe you will be ok?

 

Well, I've had one slave cylinder fail to where the car was inoperable and my second one is making scary noises at idle after the last track day. This is all on the stock clutch, flywheel, etc... If someone managed to do the same with an aftermarket clutch, it wouldn't surprise me at all.

I'm just hoping this old design slave will last me until the flywheels are released... might as well get the "free install" while you can

And on top of that, I'm really hoping the new design fixes everything. If I'm going to go through slave cylinders every track day or so, it's going to either get REAL old and/or I'm going to get REALLY efficient at dropping the transmission.

 

You can do either.
