Its time to replace the clutch and i dont know what is the proper one for my evo. I have not dynoed my evo but im guessing around 340whp. My stock clutch slips bad thru 1st and 2nd gear at only 22k miles. NO GRIP AT ALL for launches. I know alot of people are gonna say to get something like exedy double disk but i think thats way too overkill and out of my budget. I will hit the dragstrip once a month for at least 3 passes. I want something that WILL grab when launching and last a while. I do lots of daily driving in traffic too. I was looking at exedy stage 1 and stage 2. Stage 1 holds 44% more torque over stock and stage 2 holds 85% more torque over stock. I think stage 2 is more for like 400whp though. I can afford either one of these but i dont want overkill and a hard to drive evo in bumper to bumper traffic. Please help or give a suggestion on another brand. Also are the fidanza flywheel's worth it?

Shrug, you should get the Exedy Twin so that you have perfectly smooth clutch engagement for daily driving, incredible launching ability, and no worry of having to change it again soon. The price includes a lightweight chromoly flywheel, so that makes it not quite as expensive as you think. With any single disk like the ACT, you'll need to get the flywheel extra. I had the ACT w/street disk, and it held 330-340whp fine to include lots of launches, but it gave me lots of problems, so I have trouble recommending it.

I am currently using the Exedy 4-puck sprung cerametallic single disk (stg 2), and it is amazing in terms of extremely fast shifting and hard launches, but the puck style makes daily driving a bit harsher. I don't mind, but if you drive in stop'n'go traffic a lot, it may annoy you.

 

exedy twin is overkill for the street.....i woudln't recommend it for daily driver...pain in teh @ss to drive everyday..

 

sorry to high jack your thread. but id say NO on the ACT. i got a new TRE trans and put a act hdss in and im having the same issues that thrashed my old tranny. the part im sorry for high jacking about warr. what do thing of the Tilton with the hydrolic bearing. it to is in the $1500 range and carbon/carbon. what does david or al run in their car?

 

No, the $1500 Tilton is not carbon/carbon - that one costs $3k+. The $1500 Tilton is cerametallic, but Tilton clutches are awesome any way you look at it.

 

I got the ACT, and have about the same power level and have had no problems with it. But i must warn you, some people have nothing but problems with that clutch. Any puck style, if i am not mistaken, the exedy stage 2, you were looking at will suck in traffic. I am also not a fan of lightweight flywheels, but i have never expierenced one in an evo, just dsm's.

If you are on a tight budget, you can just get your flywheel resurfaced, if it isnt warped. If you want a new one, i recommend stock. I ended up getting the act streetlite, (13 pounds compared to 13.9 pounds stock) because i couldnt find a stock flywheel that wasnt back ordered at the time

 

I think i better stick with exedy then. Do i really need a new flywheel? The fidanza claims to be 9.5 lbs is that a big difference in feel? And in what way? As far as pucks, do i have a choice on how many? What is the difference with more pucks?

 

Dbdude, not sure why you're so worried about the Fidanza. If you get an Exedy, then it already comes with a chromoly flywheel (~10lbs). Haha, no, there's no choice on pucks (that's some funny stuff). Some manufacturers have 4-puck and 6-puck clutches, spurng and unsprung, but the Exedy pucked clutch is a 4-puck sprung disk. It's the one I use currently, and you can find my review in the Evo Vendor Parts and Tuning review forum.

 

Why do you say that the Exedy Twin Disk is a pain to drive everyday?

 

Warrtalon, isnt that flywheel optional. Cant i just buy the exedy clutch you have without the flywheel to save money and use my stocker?

 

i would go with a twin disk of some sort i had the act you half to constently adjust it so you dont get the 7k lockout(my next evo will not have a single disk it will only have a twin or tripple)

 

For single disc clutches, its hard to beat Exedy or ACT. Both will hold the power, but they do it differently. The Exedy uses a 4 puck disc and low clamping force pressure plate while the ACT uses an organic disc and a high clamp force pressure plate. The advantage w/ the Exedy is going to be stock like pedal feel and lightining fast shifts. The downside is going to be the on/off like clutch engagement. The advantage of the ACT is the engagement will be nicer then the Exedy, but the heavy pressure plate and disc can cause slower shifts and a heavy pedal.

I have an Exedy cerametallic twin plate and I really like it. It use to make a lot more crazy noises, but adding bigger turbos seems to have made it alot more quiet. The shifts are butter smooth w/ it, but it takes more slipping to get the car moving (when compared to stock).

 

The problem with the act is that too much slip on the organic dist to get going and you burn it up and your not going anywhere fast. that is the issue im having. big turbos need the slip and go launch. the act single is not for that IMO. i see a exedy twin in future.

 

My input was for the orginal poster that has 340whp. IMHO, anyone that drag races, w/ anything bigger then a GT30R and drives it on the street, should be running a twin or triple plate cerametallic clutch. If you live at the track, then a twin/triple carbon clutch or a ACT puck clutch would be good. In the end, clutches are all up to personal preference.
