i have the spec 3 plus clutch and flywheel i just got it put in. The directions say you have to break it in . 500 miles before you can get on it . Has anyone on here done that, how important is the break in period. And does anyone have clutch rattle , very mild does it go away or is that just normal for these clutches.

 

yes you should break it in if you want it to last... How was the install and who did it? Let me know what you think about that clutch I may be needing one eventually

 

I have only personally experienced having to change clutches on 3 different vehicles but each one has suggested a 500 mile break in period.. It has something to with conditioning everything for the heat.. It takes a few heat cycles and also to wear the newness off on the clutch disc itself... I Have never drove a cobalt that had anything but a stock clutch but I have drove other vehicles that I have put spec clutches in and I noticed that they have a harsh engage, I guess where the pressure plate springs are alot stiffer..

 

the guys at auto motion did the install,it has a litte clutch chatter but i hear thats common with a high performance clutch so far i only put 40 miles on it and im very happy with it . The guys at automotion are great people and would recommend then to every one. They did the axle install also .When i picked up the car it was flawless just like i droped it off.

 

how much did they charge?

 

$ 375.00 for the clutch and axles.

 

wow thats cheap... how long did it take them...

 

got it back the next morning. so i have my stock axles and clutch set up for sale now only 7800 miles on them,they said my stock clutch looked brand new.Need it?

 

im not sure... if im going to go through the trouble I may get an upgraded one... how much you wanting for it?

 

ill take 150.00 shipped ,clutch,flywheel,pressure plate. and 100 shipped on the axles.

 

did you drive your tvs on the stock clutch? how did it feel if you did?

 

yes the dyno guy drove it around a little wile to tune in the ls4 tb,,yes the stock clutch holds it great,no slipping whats so ever. i was suprised, i might of jusy wasted my money on this new clutch set up . t
