ok let the flames begin,,i dont care i have searched and seached,,and im in the wronge thread to..plus my grammer sux...ok. i have a exedy stage 1 clutch rb alumium flywheel and at high rpms the clutch is super soft,,dealership installed,,by a rotory expert.now i took it bach and he spaced the pressure plate with washers but it only made the pedal softer at low rpms as well as high rpms.....now when your done torching me could somebody just help...

 

The problems with the Stage 1 are well known and there is no fix that I know of. The washer "fix" has been done but with mixed results. Why do you need a stage 1 clutch? K.I.S.S.

 

The Exedy Stage1 has all sorts of problems with it. I had 2 fail on me prematurely, the first lasted 20,000 miles, the second lasted 100 miles. Exedy Stage1 is inferior to the OEM clutch. Yes, the one that is made by Exedy too. It's just the Stage1 with the problems.

Check out this thread: https://www.rx8club.com/series-i-tro...clutch-244381/

I'm not the only one with wierd problems with it, and it sounds like you joined the club. I highly recommend going back to a stock clutch. You don't gain anything with the Stage1, since the RX-8 doesn't have enough torque to surpass the OEM clutch. Paying for 1 clutch ends up being cheaper than paying for more than 1, as you are about to do.

 

all right ..thanks i am greatfull for the feedback guess im just screwed..lol ill just go back to factory..when i get some extra cash...but you dont think maybe its just not broke it...i got 500 miles on it easy drivin,,,ijust hope it doesnt harm my flywheell...
i wanted a stage 1 clutch because i felt a big lag in my factory one...like it to a while to ingage.

 

Sounds like your factory one was just dead from age.

 

Hmm... so randomly thinking out loud here... Could you use the OEM pressure plate with the stage 1's clutch disc?

I'm curious because I just helped an 8 owner replace his clutch the day after christmas, he had the Exedy Stage 1, and I figure it'll be much cheaper to replace just the PP if his starts to go all shitty on him..

 

well bump

 

There is no need to "bump" a thread 5 minutes after the last post

 

Cool cool, I was more thinking along the lines of just picking up the OEM pressure plate from Mazda (Malloy Mazda has been supporting the 7 community FOREVER and the sales manager gives great prices to 7 owners) and using that with the stage 1 clutch disk if this 8 has issues. Mazda-parts.com has the PP listed at about $220, I'm sure Malloy can meet or beat that cost and, since the clutch disk would already be mated to the flywheel all I'd *really* need to do is pull the tranny and swap out PP's if this one has issues.

Since the PP would be brand new it should really only need some brake cleaner and a quick wipe down as prep.

 

well if the oem pressure plate works let us all know,,,,please lol...would adjusting the clutch pedal help at all with high rpm clutching...since the washer trick made it worse,,this is so aggrivating,,i know there is a way to make it work ..

i can even rip hard threw 1 2 3 this sux.

 

I dunno about for high rpm, but when we put the clutch in I *did* need to go back and adjust the clutch pedal. Once the owner built pressure in the clutch pedal he was having an issue where the clutch would not fully engage even if he had the pedal bottomed out (if he tried to put the car in first it would lurch forward on the lift, reverse would pull backwards, even with the pedal fully depressed).

He had about 3.5" of movement between the point where the pedal lost it's free play, and where it was bottomed out (FSM calls for 5.12" of travel). I adjusted that and removed most of the empty travel and it worked fine.

Obviously he won't know about high rpm issues until he completes the 750 mile break-in, and that isn't likely to happen until later in the summer, as he's heading to Afghanistan shortly.

 

Each piece of the clutch kit is independantly purchasable at at least 3 dealers that I've seen. For absurd pricing (like $900 retail for everything), but doable.

 

Just noting how other people might obtain just the PP if they wished. Understood that it doesn't change anything on your end.

 

Yeah, Mazda USA doesn't (that I'm aware of) offer a clutch "kit" for the rx-8, only the pieces individually available. I totally believe that making the kit yourself can add up due to dealer parts mark-up. Thats one of the main reasons why I love Ray Crowe as an OEM parts supplier. He'll sell you the parts WITHOUT the crazy mark up

 

Ok to reply to my own question...i bled the clutch and reset my clutch position sensor ...and nothing happened..still soft at high rpms..so i said screw it im gonna drive it hard like i want it breaks it breaks....funny thing a few days later ..presto i got a stiff clutch at high rpms no more limp noodle..got to love it when a car fixes itself...
...i dont think the bleeding and clutch reset did a dam thing...i think i just broke it in with some agressive shifting..go figure..

 

My Exedy after the first race practice session on Friday. gutted

 

That sucks.

I never understood why people felt the need to "upgrade". I am on turbocharged at 10psi and running the OEM Exedy and it has taken the abuse for 40,000 miles without issue. My previous one lasted over 100k.

 

Unless the engine is FI the Mazda or aftermarket OE replacement is more than fine. Anything else other than a 7.25” or 5.5” racing clutch for lower MOI is a waste of money.

 

Doofenator, you sure that is an Exedy? Doesn't look like it and the part number on that disc doesn't list for an RX-8 that I can see.

 

I would like to see more pictures of the pressure plate. What model Exedy is that supposed to be?

This is the clutch - https://jtune.myshopify.com/products...pd-mzk-7413hdb

 

Apparently there are way more Exedy options than I ever knew of.

How do you tell a fake Exedy and are they still around?

 

Yeah, PT Barnum would be so proud ...

Probably the most problematic clutch on the forum, I believe it was also known at one time as the Mazdaspeed Exedy clutch version
