    The internet generally advises to break in a new clutch by babying the car around town for about 500 miles. Does that apply to our 308/328's as well? That would be like pulling teeth. :eek:

    I would just drive it like normal. We do not baby clutches. Even on our streetcars turning into racecars we just replace clutches then go race them.

    Well, "normal" for me is to shift at red line most of the time...but I'm glad to hear I don't necessarily need to baby it.

    A very aggressive red line shift from 1st to 2nd is what did this to my clutch disc:

    That clutch was ready to go before you melted it, you should replace it with a Kevlar unit, Ive had mine for 45,000 miles and it still works like new, OEM 3x8 clutches are weak to begin with.

    There is a "proper' way to break in a clutch and there is the "usual" way. The proper way is to do 400-500 miles of "grocery-getter" type of driving. IOW, a lot of stop/go that uses the clutch a lot, not highway driving. Highway driving does essentially nothing to break-in a clutch.

    The "usual way" is, install the new clutch, drive it however you drive the car. If that means the first time you use the new clutch is at the drag strip, then that's the break-in!

    I'd recommend the first method though I have always done the 2nd. There is no doubt that the first method will provide longer clutch life but I never had any problems with clutch longevity. Admittedly, I was never trying to get 100k miles out of a clutch so I never worried about it much.

    FWIW, I routinely run my 328 to redline in 1st to second shifts (and 2nd to third if location/traffic allows). I also do the occasional drag strip start :eek: and the clutch has yet to show any sign of distress.

    Believe it or not, I have never worn out a clutch in my life and this goes back to my first car in 85 (that I still have).

    This includes my 308 that I have tracked extensively over the past 26 years.

    Thanks Mike. Gino may be right that my clutch disc may have been ready to fail in any case, but my instinct tells me I helped it grenade when I engaged it in 2nd at high revs. I'm going to try the proper break-in method and see how I do. It may end up like the old commercial with Mr. Owl trying to find out how many licks it takes to get to the center of a Tootsie Pop.

    I too am not greatly concerned about clutch life, but I do want to avoid glazing the friction surface.

    How expensive is the kevlar clutch? Does it feel like OEM?

    Hello Dave, the clutch was installed in 2003 so I cant recall the exact cost, it was not that expensive or I would have remembered . The clutch feels very close to OEM, but with a more direct / solid feel, and boy do you get ALL THE POWER right to the wheels and the pavement, you will feel the difference for sure. Like I said 45,000 miles and 23 years later with no loss in feel or feedback as of yet, and no slipping. I dont have any issues with the clutch / throttle interplay whatsoever .By the way, I drive with just my socks on for the last 20 years or so.

    I don't drive in socks, but I do ditch the Speedcats and drive barefoot quite often. Pedal feel and control are amazing. Everyone should try it at least once.

    I'm just trying to picture someone driving a 3x8 wearing nothing but socks. o_O

    When I was younger, driving barefoot was pretty common in the summer. Now, like nearly everything that was fun, there are laws against it! :oops:

    I have very small feet, ( 7.5 ) and so driving in socks makes the small pedal box area in the 328 feel much more roomier and the feedback and overall feel is great for me .
