thoughts on this clutch
 
I'm preparing to replace my lightened flywheel with the OEM unit.

In the meantime I wanted to upgrade to a new Pressure Plate as mine has just reached the limits of the clamping force.I was planning on a ACT Xtreme PP as it should give me able 80 more TQ to work with.

However I came across a local deal form a friend on an almost new clutch kit from Competition Clutch. Anyone have any thoughts on this type of clutch, should prove to hold lots more HP...



This segmented Carbon Kevlar material with a performance pressure plate will provide the ultimate in street and strip combinations. This assembly is suited for 150% increase in torque capacity. Provides quick but smooth engagement and extended life. 500 mile break-in REQUIRED with this set-up.
The 2300 Series kit includes a performance pressure plate, a high torque sprung disc with antiburst steel backed Carbon Kevlar facings, all applicable bearings and the appropriate alignment tool.

On paper it looks good.... its tough because with clutches I tend to stick w/ ACT as they are just well known to me.

Braineack 01-05-2007 12:55 PM

yeah, I'm the same. I really like how ACT at least tells you what TQ to expect it to hold. I know little about Competition Clutch and less about dual friction clutches.

Price might help decide is their a noticable difference. Does it matter to you.

Braineack 01-05-2007 01:00 PM

yes, I'm a cheap bastard. The price is right for what I want to spend. Then I'll part with my current clutch and flywheel only 7-8k on them.

kevlar is a tricky one. it doesn't have as high a friction coefficient as organic but is allegedly reputed to last longer. however.... once you glaze it (and you will :vash: ), it will suck bawls.

i say stick with organic for street cars. increase pressure plate clamp force to add power.

Braineack 01-05-2007 02:28 PM

I can get this setup for cheaper than just any PP, I guess I can always try it and keep my disc handy, and at least try it with the PP if the disc goes bad.

At least it's a dual friction kevlar / organic and not pure kevlar.

I have heard those are pretty awesome for the price.

Braineack 01-05-2007 02:54 PM

i might as well try it....from what I'm reading the kevlar / carbon are a nice dual friction, same material as Spec Stage II+

The price is worth it. If it glazes, then I'll replace it.

My ebay clutch is awesome so far. Im just waiting in a mbc to crank up the boost. I have no idea why i didnt buy one at the same time i ordered my new actuator....

The early FM/clutchmasters kevlar clutches were nice if you go ones without the defective rivets on the disc. Held great and had no Superman pedal pressure like the ACT XP. If you glazed them they would eventually recover with some regular driving.

i went with act for 2 reasons.
1. i had one before behind my 4g63 and it took a beating
2. people might have complaints about it but i didn't find anyone complaining that it failed or didn't hold the power

hustler 01-07-2007 01:41 AM

the only problem I know of with act is the shitty pedal feel. I had a kevlar clutch like that and the center section started wearing/grinding into the flywheel. I was pretty pissed.

Looks like a Spec Stg. 2.

miatamania 01-07-2007 10:46 AM

Any idea when you think you might be swapping them out? I'll go ahead and set aside the money for the flywheel...

looks more like the spec stage II+ since it's a kelvar/carbon, not plain kevlar.

not quite sure yet. I'll let you know.

miatamania 01-07-2007 01:15 PM

Thats fine.

On a side not, how much does that setup run?

Braineack 01-07-2007 01:45 PM

New $595 for the clutch kit. I'm not paying nearly that much. I'd personally rather have a ACT XT kit for $320, however what I'm paying is less than that as well.

If it holds well I'll have my ACT HD kit for sale as well which only had 8000 miles on it, holds my 200rwhp perfectly fine.
