Putting in a gen5 clutch in a gen 4. Worst mistake, I've done.
 
Yes, it was professional installed but if you want to ruin motor mounts, eventually ruined your front end and have hard shifting for the rest of the life of your car, by all means. I mean its a nice clutch and all, and I did buy it off DAVE B but the gen5 clutch grabbing all harder and having a more clasp pressure just eventually made things weaken as if they weren't built. (which they weren't) to the added shock and pressure to the gen 5 clutch.


ever since I had that installed hard shifting the worst part, unless I let go of my clutch like a baby, yeah it won't be a hard shift but if I let it go regular, you can feel the hardness of the grab as well as the slight shake or stutter. Now is this a theory? Possibly but I can't see all these things getting worse ever since I had it installed and its been 2 years ago this month since the brand new gen 5 clutch was installed.

Just my 2 cents, If it fits, don't bother because the car wasn't still MADE around it in the first place. Same part number or not. I should of just put a gen 4 clutch in, but I listened to everyone here who always wants that last spec of performance out of our maxi's if it fits.

LOL. you're ranting about a STOCK clutch when people use Stage 1, 2, 3, and even 4 clutches in theses cars....

Hmmmm. Thats like saying that the dek motor in your 96 max is stock.

I've had an aftermarket clutch in my previous gen4. Very strong. Too strong really. I could almost feel my drivetrain stressing from the shock. Next time i'm going oem or as close to it as possible.

Kevlo911 Jan 27, 2013 06:26 AM

ive been running that clutch for 5+ years, NONE of these issues...

036mtmax Jan 27, 2013 06:56 AM

This is why you spend alot of time doing research before you purchase something as crucial as a clutch. It took me a month before i could figure out what clutch to buy. I searched on here and even Subie and STI forums to see what there thoughts were. I ended up with a clutch that could hold a ton of power without any chatter at all. Did you ever think your motor mounts could be bad, Air in the clutch line,Warped or bad flywheel causing it to engage funny ? There are alot of other variables that contribute to pedal feel and the way a clutch grabs besides the clutch itself.

Did you reuse the original flywheel?

but its not really "STOCK" and those people put those in when they braced and modded everything else in the car to handle it poly mounts etc. Technically I don't have a stock clutch. Stock would mean for my exact car, and it isn't.

normal stop light Launching isn't an issue cause I baby that, but I have a weak knee from tearing my MCL in MMA last year so I can't really just baby every single one. I like to let it go like a normal clutch but the car shakes a little or you just notice a super tight grab. I couldn't imagine the pain people go through with a stage 3 if they no longer race. I heard you can't even baby those and if you do, the car stalls.

I put brand new motor mounts in before I did the clutch, and yeah I am not sure about the flywheel but the guy did say he resurfaced it. I have bled my clutch line since than and I never even bothered to adjust the clutch pedal like I had to do at one point because of the old clutch getting really hard to grasp as I had a lot of miles on it. The pedal itself feels fine and it grabs in the right way, its just when I normally drive and let go of it in a normal fashion I get shutter on the let go, not to mention now my motormounts are shot again.

I want to go poly but my maxi has 235k miles on it and my tranni is not the best condition. It whines now pretty much in lower gears. I am sure that is a totally different area but that did start happening a lot more since I had the clutch done, makes me wonder if the dude either just installed it wrong or if that added stress did a number on my tranni as well. He is transmission specialist too.

yes, but he said he resurfaced it.... probably a mistake... I wanted to buy a new one but he said I didn't have too and he even said you don't even have to resurface them "SOMETIMES" ha, makes me wonder if he even did resurface it lol

There's your problem right there. You can't resurface out hot spots in the flywheel. That will always, always, always cause problems. You need a new flywheel.

036mtmax Jan 27, 2013 08:10 AM

Well the way i look at it you did it two years ago and if it was fine then and you didn't have a problem then maybe it is something else. It sounds like the flywheel has hot spots causing it to chatter. I was in a different situation when i needed a clutch because i was boosted. Still stock motor mounts and no poly bushings and i was fine. Engine moved a little more than i cared for but it didn't cause any other problems besides blowing up my transmission which was my fault for rashing on it a little to much one night. I had an ACT 6 puck sprung hub clutch that was meant to hold up to 500ft pounds of torque, That mated to an aluminum flywheel should have rattled my teeth out of my skull but it didn't. It grabbed hard as hell and it was a really smooth engagement with light pedal feel. I did alot of research on the setup before i bought it because i knew i didn't want to take it back out and swap another one in.

did you put oem mounts?

no... too expensive and yeah that was a bad idea not too. I just couldn't afford like $150 a mount when I needed 4 of them.

There's your problem right there. You can't resurface out hot spots in the flywheel. That will always, always, always cause problems. You need a new flywheel.

I heard different pressure plates tho?

As far as stock 4th gen vs. stock 5th gen? Not 100% sure of it, but I don't believe so. Besides, having some extra clamping force is good. Since our clutches are hydraulically assisted, you probably won't notice a difference in petal stiffness even with an upgraded clutch. Drive a car with an unassisted aftermarket clutch, and yeah... You're going to end up with a strong left leg. :laugh: My dad used to have a 69 Mercury Cougar 4 speed, and it definitely separated the men from the boys! :D

Kevlo911 Jan 27, 2013 10:19 AM

btw was your clutch an oem exedy clutch or a "key value" clutch?


as far as the non oem motor mounts, they are a number of them out there and a bunch of them are ****ty. i work in motor mounts for chrysler and the aftermarket mounts are horrible compared to other aftermarket replacement parts; they just havent figured out mounts yet...

I dont get what your trying to say. The DEK is almost a direct replacement for the stock 4th gen motor. Every mount and bracket fits the same, since I'm using 5th gen motor mounts that came with the motor and my stock tranny mount. The 5th gen clutch is arguably SLIGHTLY stronger. But definitely not different enough to validate the OP's complaints. Sounds more like either poor installation or badly worn parts.

maxgtr2000 Jan 27, 2013 11:26 AM

Yes, something wrong here. The clutch I have is stronger than the 5th gen and my mounts are all oem, never changed, the car drives smooth. You said you can't baby it because of your knee, so if you slam it when shifting it will respond accordingly. If you don't think it is your shifting, I would imagine the possibility of the sprung center having a broken spring or 2.

You're probably right about the clutch stuff. As for your car, come on, if you take your car to the dealership for service and they pop the hood, they'll be like NOPE!

Of course I do admire your skill in actually doing it. I'm going the "easier" route with an 00VI

CMax03 Jan 27, 2013 01:15 PM

Curious if the 4th and 5th Gen 5spd clutch disc are dimensionally identical to the "T".... if so they should perform relatively the same unless they have different material composition.....

CapedCadaver Jan 27, 2013 01:20 PM

i've got an Exedy stage-0 clutch in my VG 3rd gen. 40k or so miles on it, no problems at all. would buy again.

CMax03 Jan 27, 2013 01:28 PM

I'm thinking the Thread originator had defective motor mounts from the very beginning.....

Perhaps, but the clutch chatter and the "grabbing" upon engagement as described almost always points to flywheel hotspots.

njmaxseltd Jan 27, 2013 05:43 PM

It was all OE materials used, should have been smooth as silk with the ability to hold more hp before it slipped. The complaints from the OP all point to a poor installation, not a mismatch or poor quality of parts which we all know, from experience, isn't the case here.

RA030726 Jan 27, 2013 06:35 PM

Having driven a car with clutch chatter, I feel your pain. However, its an install issue or worn parts. Its not the clutches fault.

Nealoc187 Jan 27, 2013 08:05 PM

it's not the clutch's fault unless it is actually defective.

as per normal, it's probably OP, not the part...

perhaps but they were brand new. Some high up guy on here told me to buy them off this dude on Ebay. Total was $150 for all 4... Another worst mistake I made on this maxi... Don't buy **** off ebay.. even if people tell you too

so whats going on is called clutch chatter? hmm. Anyway to fix it? or should I just deal? I probably need a new flywheel by the sounds of it. And motor mounts, and balljoints for the 4times ugh.


also if you downshift hard. The car shakes violently its horrible lol, makes you look like a noob if you don't blip the gas and baby engage back to it.

You downshift hard and expect the car to engage smoothly like a Cadillac automatic?

aackshun Jan 28, 2013 06:42 AM

6mt swap it, your clutch problems will go away.

Can't fix clutch chatter without doing the job all over again.
