My friend Chris Arrow, Cowsniper is his SN on here. He's got the Spec 3 as well. He smoked it on the dyno with only 430 whp while Kan was tuning it.
We were pretty suprised too.

Thats what happened to me. But around 500 I thought I was spinning on the dyno but no rubber was present. 2nd clutch I bought from Spec and was promised this would hold up to 500lbs. ******* liars!!!!!!
So do I have to go with a Exedy twin plate or is there a cheaper out?
I do not mind spending the money if this is what I need and I sure do not want to waste more on another questionable unit. So whats proven to hold 600+ (as thats my goal) and help give me some killer 60 footers??

I used the ACT 6 puck on my last FD. I abused it for 5 years and it held strong. Numerous 1.5X 60 foot launches and even a few 1.4X launches. 603 whp and 500 Torque.
I've seen some people claim to put up big power with the Spec 3's so I don't know what's up with that.

6puck disk (personally prefer it over 4puck anyday) also its ceramic coated 
just try to burn it up 
Also higher clamp load on the pressure plate.

I have the ACT 6 puck unsprung. Its not that bad. I had to daily it for a week when one of my other cars was down. There is no feathering the clutch up your drive way. Its a on/off switch. I don't have any problems anyway.

I alway struggle driving it if i haven't been in the car in a while, but after a little while of driving it, i get back in the groove. If i drive the car all week, i don't even notice the it anymore.

Break-in is KEY to making a clutch survive. I have pulled one out of a car with 400 miles on it that was still going through "break-in" procedure as per SPEC's instructions and only half the clutch disc was actually contacting the flywheel! At that point you only have half the holding power and are very prone to glazing the disc, at least until fully broken in. Once it was fully broken i, it felt MUCH different, and held anything that was thrown at it.
I think a major cause of clutch failures is because people don't bother to break it in properly. They simply install and go, or strap it to a dyno and do full throttle pulls. Not a good idea...

Mine had over 1k miles before hard pulls! 3k on it before it started slipping...

Have fun, I have run it on a daily driver and be prepared. I have another one here with less than 100 miles on it I would have let it go for pretty cheap.
We have also ran spec stage 3+ and exedy twin discs. Both work very well. The twin disc can be noisy. I think you had a different issue, as both have been on cars here putting down 500-550whp

"Where did you find that? I am looking for a sprung one..and that price is great compared to others i see other there"
Just bought it off a member.

I am thinking the same Sean as I just got off the phone with SPEC and they told me the same thing. The 3+ is rated above the stage 4. Rated like you said 598ftlbs! He thinks I either did not break it in correctly or its still not sitted all the way. Sucks for me as I have to make a choice now on what to use. I am going to post link to a inside ride along showing the clutch slip. Let me know what you think. (tonight)
