Clutch upgrade is awhile away for me (knock on wood), but isn't the stock flywheel pretty light? Any info on how much lighter the Fidanza flywheel is?

I had a pretty sweet Spoon flywheel in my N/A Integra GSR. Sometimes people report that a light flywheel makes it harder to launch the car or drive in stop and go traffic, but I did not experience this with my Integra. It did take a little getting used to for downshifts since the rpms would drop quite fast between shifts. However, rpms would go up faster too.

Anyway, this would be good info since I would try to get it all at once when the time comes.

Take care,

yeah, it's crazy now because when the car revs it takes the tach a split second to catch up, and btw, there was no loss in daily driveability really and I live in the hill country of texas where the car is put to the test every day. oh and I also have a B&M short throw, adds a nice touch to the whole set up.

 

our stock flywheel is aluminum, weighs 15 lbs, the Fidanza unit weighs in at 8.5 or 9, I forget, very noticeable upgrade.

 

Exedy have 2 types of single plated clutch

1. Hyper Single Sprung Center Damper

2. Lightweight pack Solid Center

whats the main difference between the 2?

 

I would like to know also?

 

one uses a spring hub, one uses a solid hub. Solid hub is not nice to drive on the street at all - just hooks and goes. The spring hub is much easier to modulate the pedal on, and far less prone to chatter on takeoff. Much more driveable clutch all around

 

You're mistaken there buddy, the stock flywheel is made of iron.

 

no crap? wow my bad, could have sworn that someone told me it was aluminum, all in all it's not that heavy for a stocker, weren't the lightened flywheels for the dsm's like 15lbs

 

The good thing is that it's not gray iron. It's either ductile iron or forged, both of which are SFI approved materials, if the properties are correct. Good stuff!

 

For daily driving, get a twin-disc clutch - they're supposed to be much easier for daily driving if you're getting one with decent gripping power.

Also it's only 300whp you're asking about... you don't need a monster pressure-plate or gripping force for that type of power. The stock Mustang SVT Cobra runs a T-56 Tremec trans. I don't have the number for its grip pressure but it's a totally daily driveable clutch (I test drove one last week). It's the same trans found in the Corvette and the MkIV Supra, from what I hear, and it's known for its superior durability with those powerful engines. Clearly Corvettes and the Cobra put more than 300whp to the ground stock. So find out what the grip strength of the T-56's clutch and pressure plate is and don't bother yourself with anything much stronger than that. A lot of silly kids like to go YO I GOT ME A SIX PUCK SUPERORGANICKEVLARCARBON CLUTCH AND 50,000LB PRESSURE PLATE AND I DRIVE DAT ISH DAILY YO AND IT AINT NO THING. Just ignore people like that - they're idiots and they are torturing themselves for no reason.

JRock, DUDE thank you so much for finally saying this, it's about damn time someone did, I laughed out loud when reading. It's funny when some people ask me about my car and they hear that I have an upgraded clutch they immediately ask "Is it a stage 3" or some crap like that, when I explain to them that it is a 2900 lb pressure plate set up they just have this really confused look on their faces. I would like to drive an Evo that has a twin disc set up, bet it feels nice.

 

I have over 300 whp and have been using the HKS GD Max Clutch. It's a twin disc, sprung hub. It is my daily driver and then some. I ran about 10 times at the track Tuesday night, launching from 5K up to 6.5K and it grabs as good as ever. Not to jumpy, and the pedal feel is like butter. I believe it's made by Cusco, w/ an HKS tag on it. I'd recomend it.

How's the noise chatter with the twin disc? I hear it can be annoying

 

well it is loud at times, but it's a very small price to pay for the performance. i believe that they're meant for all out race applications, so it's going to be a bit loud when you let off the throttle. all in all, it's a nice conversation piece in the car .

Since I'm not going all out racing I think I'm going ACT then. Any other clutch recommendation for mostly street use and maybe 1 or 2 times at the track. Need to handle up to 350-400 hp and 400lb tq also.


Thanks
