I bought (and will be installed soon) a Spec stage 4 clutch with a Fidanza aluminum flywheel. My question is...Is the wear pad thing on the flywheel going to wear radically fast because of the 6 puck unsprung clutch? Or will it be okay for a decent amount of time, I only drag this car a few times a year and i'm pretty easy on the car except for the occasional streetrace. Let me know what you all think, thanks for the input!

 

you have a stage 4 with not even full bolt ons? just seems kind of excessive

 

I'm planning for the future, this car won't be like this for very long. I'll be doing a heads/Cam setup probably by march or so. Anyways, anybody got anything for me, will it wear excessively or will it be good for awhile?

 

well stage 4s are meant for prolonged periods theyre mainly a strip clutch and might not have a very likeable engagement to drive on the street, driving it often on the street it'll probably wear fairly quickly

 

I pretty much knew exactly what I was getting myself into with this clutch/flywheel setup but yeah your right about the harsh engagement and all that stuff, but im not worried about it, this car wont be my grocery getter for very long. Its actually not that kind of car now, and I don't even drive it everyday, thats what I have my street bike for. Yeah, so im just gonna assume that it will be alright for awhile. Thanks man.

 

i have the Spec 4 with the Fidanza in my cammed LS1... i've got over 5K miles on it now.

i had to pull the trans recently to replace a broken slave cyl. the flywheel was worn, but not that badly. and the clutch disc had very minimal wear off of it, and i only street drive the car. never had it to the track in 4.5yrs.

engagement is hard and pretty rough at slower speeds. but basically its only in 1st gear and sometimes 2nd. 3-6 are all smooth.

i figure if the flywheel or clutch only last 10-15K miles....i'm good for about 5yrs. at which point i wouldn't have a problem tearing it apart again.

 

Teke184, Thanks for the input, thats exactly the kind of useful information that I needed. Thanks again! Peace.

 

I think he just told you want you wanted to hear. The truth is (as mentioned by someone else) that the spec 4 is really a drag clutch. It really doesn't matter what plans you had for it. That doesn't change what the clutch was designed for. ever heard the saying "You can call an apple an orange .......but its still an apple" same thing here. yes it will hold up for a while or maybe not specs are just all over the map. I have seen specs go to hell fast. And some last a while.

Aluminum flywheels really are for mildly to moderately modded cars. If you are going to make gobs of power then a billet steel is better.

Spec clutches are hit or miss, and more times than not its a miss. You just can't install it and forget about it. Things tend to happen to them.They are not like Mcloed's or Textralia's. I have had a friend running a Mcloed twin disc for nearly 20k miles and on spray he makes about 640 to the wheels. In the 2 1/2 years he has had it....not one problem. He installed it and that was pretty much it. My Textralia will be here in 2 weeks.

 

I've run Spec #3 clutch for 6+ years (2nd disc) and an Alum fly (Spec) with a 1080 steel insert. I changed both the 1080 steel disc insert and clutch when I replaced. The spec_3 disc was wore down to the rivets. I have not have any problems with Spec and breaking-in period can be a little rough. I like the Alum fly since it alows fast revs, but, not much fly inertia for slow starts. I usually engage clutch fast for reduced slip. Hope this helps. B.

the spec 4 is a drag clutch....

and as stated, there are alot of stories about spec clutches failing. but in all reality there seem to be just as many on alot of other clutch setups.

one of the main complaints about the Spec clutches are the springs givving out on the clutch disc. well by going with the 4, you eliminate that since its a solid disc. yes its pretty harsh to drive around, but for someone who drives the car 3-5x a month....and never in anything resembling "traffic"....what difference does it make.

as for the combination with the light flywheel. i've had the car for almost 5yrs. and so far i've never had it to the track, and honestly, i've street raced it (against an opponent) ONCE.
however i like to drive spirited and i also have the car (and have more plans) setup for more of a canyon carver than drag car. so the fast reving, quick shifting attributes of the Fidanza work well for me.

but hey....its your car...
