I have no problems with the new stock clutch I put in 3 yrs ago but I don't run alot of power. Consensus in the past has been the Act S/S for moderate power.

I love my ACT clutch. It's a sprung hub organic disk with the extreme pressure plate. Pedal pressure isn't a problem but it holds like a mo fo. I considered a 4 puck or maybe 6 but I always get caught in bumper to bumper traffic.

4 puck Spec clutch! It is a sprung hub, so there isn't much chatter. 522lbs.... Oh yeah, pedal is *lighter* then the stocker, or so it felt. For those that don't know spec, they make some seriously good stuff.

So which are you gonna buy and what kind of driving are you going to be doing with the car? Are you road racing, drag racing and what power do you expect to be making to the rear wheels?

rx7raca

well, i want to to get more involved in road racing, and of course the street racing against those rice boys, and for power, over 300 but lower than 425whp or so. im not going big power, but still pretty quick.

im really thinking about getting the racing beat 6 puck race clutch, but then i read what jason93rx7r1 says, and that might change my mind. im not sure which im going to get. most likly though either the racing beat or the ACT.

thanks for your help guys, keep em comin, always cool to read what people have and how it performs.

ps: one more question, has anyone ever disliked the ACT clutch? i never hear anything bad about it, and wondering if there was anyone out there that didnt like it.

rx7raca,

Exactly what are your goals with the clutch here? What do you want out of it?

An ACT S/S will do you fine. A Spec clutch would do you fine. A Racing Beat 6p will also do you fine. Even Pineapple too. They're all more than capable - but exactly what are your concerns?

rx7raca

the whole point of this thread was to figure out what clutch is best, and which would last longest. but really these are pretty common and newbie questions.

the main clutch that i wanted to know about was the exedy 6puck, because i know a guy who is selling one. used but in good condition. so i was trying to figure out if i should get this clutch or not.

one question that i would really would like to know is, can you use any flywheel with any clutch?
ex.exedy light fly with ACT clutch.
thanks

Main thing that you need to think about is chatter. An unsprung clutch, like many 4 and 6 puck clutches, will be a bitch if you are in traffic. That is exactly why I bought the clutch I did, most every other one I found was a seriously hard pressure plate or super-chatter-ville.

Spec all the way.

EXEDY SPORTS & PERFORMANCE CLUTCH PRODUCTS

Hyper Single Clutch:

The Hyper Single Clutch is engineered to optimize performance for cars that are moderately modified, but do not require the clutch capacity of a multi-plate clutch. Similar to our multi-plate clutches, it has a forged aluminum cover that is anodized purple. The aluminum cover is stiffer than a stamped cover and therefore allows a higher lever ratio to maintain the pedal efforts at a reasonable level.

All Hyper Clutches come with a steel flywheel and a 6-puck cerametallic facing, spring center damper disc assembly. The disc is generally smaller and thinner than the OEM disc making for lower inertia and therefore quicker, easier shifting and less wear and tear on the transmission synchros. The higher clamp load and cerametallic friction facings give approximately twice the holding torque of the OEM clutch and generally higher than other single plate clutches.

As with all cerametallic clutches, the street driveability may be marginal due to chattering and harsh engagement characteristics.

An additional feature of the pressure plate is a series of turbine-like, air flow enhancing vanes that keep the clutch cooler under extreme operating conditions to improve wear life. For Purchase information Please Click Here: :: EXEDY SPORT & PERFORMANCE CLUTCH SPECIALIST'S ::

Multi Plate Clutch:

For high-powered applications, EXEDY offers twin and triple Multi-Plate Clutches. These are designed for hot street action as well as drag, road and rally racing.

The twin plate clutches are rated for above 500hp to 750hp. The triple plate clutches are rated for up to and over 1000hp (for drag race applications). Twins come as with both spring damper discs and solid discs. Triples are all solid discs.

All of our multi-plate clutches come with a lightweight, chrome moly steel flywheel and the famous purple anodized forged aluminum clutch cover. Depending on the application, we have both strap drive and lug drive models. All have T5001 cerametallic friction materials for extreme heat resistance.

Engine modifications e.g.. cam-timing-turbo modifications etc. cause engine pulsation and vibrations. These vibrations can cause clutch rattle when the clutch pedal is depressed by movement on the intermediate separator plate in some applications. These noises will in no way affect the performance of the Exedy Multi Plate Clutch. This rattle is well accepted in the performance industry where engine modifications have been carried out.

Single Plate Organic:

EXEDY Racing clutches with organic friction materials use only premium friction materials that are resistant to slippage and burst. Increased clamp loads give the necessary capacity to handle modified engines.

The driveability will be like a stock clutch. Pedal efforts will be higher because of the higher clamp loads. All of our clutch discs have high capacity spring center dampers to reduce the drive train shock and impact.

Single Plate Cerametallic:

EXEDY cerametallic clutches are designed to handle the abuse of high power modified engines. Our cerametallic friction material can handle much more slippage than stock type disc assemblies without slipping and fading.

All EXEDY cerametallic clutch discs have spring center dampers to reduce the impact and shock loads put into the drive train. This protects the transmission and the rest of the drive line system.

We offer two types of cerametallic discs -normal thickness and reduced thickness.

The reduced thickness (thin cerametallic) discs offer greatly reduced inertia to improve shift efforts, make for faster shifting, and improve synchro durability. These discs are approximately 1/2 the thickness of a stock disc.

The normal thickness (thick cerametallic) discs have better heat capacity and therefore better durability in demanding applications such as all wheel drive. Even with the normal thickness, our three puck cerametallic discs still typically have less inertia than a stock disc.

With any cerametallic clutch system, there will be some compromise of start up driveability as compared to a stock clutch (chatter on light throttle, low rpm start up). This characteristic is generally felt to be acceptable in modified performance cars. Drivers of cerametallic clutches on the street should be warned not to "ride the clutch" to try to reduce the chatter as this will greatly increase the wear.

Racing Flywheels:

EXEDY Racing Flywheels are made from solid one-piece billet chrome moly steel or chrome moly steel forgings. They are specifically designed to reduce weight and inertia for better engine response. Most incorporate special design features to enhance the air flow to improve the cooling of the clutch. The ring gear teeth are milled onto the flywheel unlike an aluminum flywheel where the ring gear is pressed onto the flywheel which has the possibilities of separating from the flywheel. This could cause the flywheel to explode due to two different expansion coefficients (aluminum flywheel pressed on steel ring gear). EXEDY steel billet and forged steel flywheels have passed engineering tests to 15,000 rpm. They are guaranteed to be explosion proof at the said rpm.

has anyone ever used the exedy that could tell us how they liked it?

rx7raca

how does the 4 puck feel? and how long do they last? i havent really heard to much about them.

I use the spec in my car and love it. Well worth it and for a puck clutch its very easy to drive.

Jason

Jason93RX7R1

I think that it is one of the understated and rated clutches for the FD. It is simply keeps a nearly organic feel with a very light pressure plate, but will 500+ ftlbs of holding power. The key is that its a sprung hub, as mentioned before. A unsprung hub puck clutch and chatter can be nerveracking for street use.

rx7raca

how long have you had it in the car?

Jason

iTrader: (5)

probably 4000 miles or so.

Jason

rx7raca

still grabing good? and how long do you expect it to last?

Jason93RX7R1

Mine had 10k on the clutch when I sold the car. And that's no highway miles, all hard street/city miles. (Ask the STL guys how grandma-like I drive ) The damn thing will grab regardless of gear or speed or if *try* and burn it, no way it is slipping once you let it out.
