Spec III Clutch Help
Watch out...
Remember, brakes are for braking. This topic however gets alot of press. For everyone who likes a Spec clutch, there is another that doesn't. I don't like Centerforce for example. I do like the STGIII. Mine is much more forgiving now with a few Kmiles on it. For a reference, I like a big thumpin cams, open exhaust and the smell of C-16 in the morning as much as riding in a plush luxury ride. Good luck.
stockers, let me make a note here as well this not just a chatter i mean it shakes the whole tranny and rear of the car. I checked every bolt and i know that i installed the clutch right so i hope that this is normal. its like a wheel hop almost on downshift
EXACTLY!! wheel hoping on downshift is the best way to describe it. This will happen with any manual, wether it be a car, truck, or even a motorcyle. If you are running at a high speed, and put it in a low gear, without rev matching, it will hop. Hell my lawn mower does it sometimes! It will shake the car, the whole drivetrain, everything!. If you keep it up, something WILL break!! Best of luck to you... I dont know if there is any help out there for you except learning it the hard way. Having pieces of your ten bolt blow through the housing or throwing a driveshaft through the floor, or your transmision going out...Everyones told ya the same thing.
And yes, most guys on vette forums ARE infact dicks... Im learning this the hard way too. I got the vette, and would prefer to stay over here on the fbody forum.
mine has been fine for 8K miles (more than 2 years) and its been used the way its meant to be. Probably 25-30 track passes on it, plus street use. Ive never noticed any problems with downshifting though, but Im a natural at rev matching
If you do a search for everyone that has spun a bearing after a higher mileage cam install your going to get alot of feed back as well. Does this mean that the majority of people do this? Yeah there are some people out there that dont like them that bitch on here. There are lots of people on here that do like them, have had good luck, and just dont post. So of course, your going to hear about something more that is not liked and goes wrong than things that are liked and gone right.
Is this only regarding the Spec III? If so, you really can't throw out a blanket statement saying Spec sucks. I too have heard from different boards about the chattering problems people encounter, but after having a Spec IV in my car for over 2 years now I've never come close to having a problem with it. The others I've known and read about who've had the same clutch as mine are just as slap happy.
There's plenty of guys that had the same problem. I just experienced some of the same problems that other had as well with chattering, dissengagement problem, weaing out in under 5K miles of us... broken springs. I ran through about 3 of thier clutches before I quite. And you can't compaire a spun bearing to a defective compenent supplied by the same manufacturer. I don't get paid to talk about spec, I just thought I'd try to help a few people from going through what I did. Having a clutch blow apart on you at 100mph in the middle of a race is not fun, it's dangerious.
