Spec V??? I have a '01 Z that will make 800+ rwhp at 14#. While tuning on the dyno, the RPS clutch that was in there said good night @ 5K with 700+ rwtq and 740rwhp and climbing. I have blown up almost everything single and twin and spent enough to convert to an A-4.. But It is staying a stick.. I am down to the Cartek clutch or a Spec V. Give me the good and bad of both... Drag racing, street driving...etc.. Are Spec-V's all that terrible to street drive?

The spec 5 is a sinterd iron disk. It is pretty harsh on the street but its the nature of the beast. Its pretty much a full race clutch, the engagement is verry fine and it makes a sqealing noise when being broken in. It really depends on what you consider streetable, sure its harsh engagement, but its do able.

I've had a Spec 5 for about 5,000 miles and probably a minimum of 50 hard launches. Other than the squeal some of the time I have no complaints. The clutch pedal isn't much heavier than stock. I only dump the clutch, usually at 4,000+ rpm, no feathering. The clutch requires no break in. Make sure you get a billet flywheel when you get the clutch.I always have the clutch and flywheel balanced locally. My machinist said the balance was pretty good right out of the box. He also told me it kept the same balance through a wide rpm range, appearantly alot of clutches are very difficult to balance, because the balance changes as the pressure plate is sped up.

Thanks guys... I did order the billet flywheel too. And yes, I am having the whole assembly balanced locally before installation. I did not know that it needs no break in, but that makes sence. What is it like in the water box? Just drop in 2nd and dump it?? Anyone else with 2 cents...

I'm happy with mine. Other than the squeal, it's fine. The engagement is not "on / off" like you would think. It slips enough starting off. If it was my DD I would not have it, but its great for what I use it for.

What do you think the average life on a Spec V would be for a Street racer who takes the car out on Saturday night and goes to the track 4-5 times a year? (maybe 15 passes annually) If I am street driving it does it shorten the life dramatically?

We track the hell out of those cars,only clutch that has actually lasted in them.We use to go through 2-3 SPEC 5's a year
