I'm going to be getting a new clutch for my camaro shortly.

Currently it's running under bolt-on power and will be for a few more months until I can smog it, then it gets the GM847 treatment.

That being said, I'd like a clutch that will be easy to drive on the street but hold up to the power of a GM847 and ported heads.

I've been looking at the Spec 3 since it's supposed to be nice and streetable, but for $20 more I can get the Spec 4, but it's supposed to be not street friendly at all.

This car won't be daily driven so I'm really leaning towards the spec 4, but can someone with experience with these clutches chime in? Is there a big difference in the drivability? This will be driven on weekends/friday nights, that sort of thing.

The price is alright, $850 for the clutch and flywheel, but that's from Spec themselves. I'm sure I can get it cheaper somewhere else I just don't know who I could trust to buy it from. Any suggestions?

Thanks for any input.

 

Ha ha ha ha...


Um... Spec sucks. They either slip, chatter like hell, or are on/off switches, or all of the above. There are FAR better clutches out there for similar prices.

 

Like which ones?

 

I haven't had any issues with mine... IMO they suck for people that don't know how to drive a clutch

 

I had a stage 3 before I got the stage 4 and I actually think the stage 4 is easier to drive. Great clutch though, people bitch about it alot, but I haven't had a bad experience with them, yet, after 3 years or so of using them.

 

i have a stage 4 ND Hve no issues, except for a little chatter but thats do be expected i think with this type of clutch. I drive it about like what you drive yours and have no issues, it holds well enough to bark 4th gear with 295s on the back.

 

I have a Spec 4 with 355 rwhp. I love it personally, you just have to find the sweet spot. Just think, for another 20$ you wont have to upgrade for a long time?!

 

Yeah i've been reading alot of positive reviews about the spec 4 as opposed to the spec 3 (spring issues).

Does anyone know how long they last? About how many miles?
How bad is the chatter, really? I can put up with alot.. I drive my car with open LTs as it is..

I'm thinking about buying - this one - from a seller here on cz28. That is a stg 4 right?

 

i've got the Spec 4 on my cammed LS1...about 7K miles of street driving on it. when i pulled it to fix a broken hydrolic line it barely had any wear on it. called spec for the "stock thickness" and they said .310"...mine was still .305". they said if its out of the car, and .280", than change it, but it still will wear more than that.

i have the clutch mated to a fidanza lightweight flywheel, which makes it a little trickier to start from a stop. with the quick engagement and the lack of rotational inertia of the flywheel, it's easy to bog it down and stall it.

but after breakin...which took 1000 miles...it totally stopped chattering. i have no complaints.

it's nice to know you have a clutch to handle plenty of power, but don't have to worry about the hub springs giving up the ship on hard launches. i'm happy with my purchase.

i picked up my fidanza flywheel for $299 shipped on ebay. chech out there for good prices at the ebay-stores.

 

I haven't noticed much chatter with mine at all, I drive with open LTs also. Personally, I don't mind its being rough to drive. I don't try to pull into tight parking spots with it either. Works fine for me.
