Flexdisc wear observations
During the test drive when purchasing this vehicle, the OE PO mentioned that he liked to downshift instead of braking, he asked me what I did, and I said that "brakes are cheaper than clutches" and I used the brakes when I wanted to slow down.
Fast forward 1 month while doing some unrelated brakework... Well the flexdiscs appear to be in good shape @ first glance, no blatant cracks or loose reinforcement material. But if you grab the driveshaft and twist, it will move almost an inch! Then I saw the spot where it had contacted the muffler a few times, then I saw where the bolts and grommits were loose in an oval wear pattern that used to be a tight grommited holes in the flexdisc, then I saw how the boot for the center driveshaft bearing was completely torn... What I learned from this... Forget clutches, Brakes are much cheaper than your entire driveline

its the 84 w/ 123 on the clock and a broken (rusted) odometer cable.
The flexdiscs looked newish upon casual inspection, not at all dried out or weathered looking, I doubt they were OE... (BTW another important piece of the puzzle.... Clutch was replaced @ 100k!?!)

Oh, on the Euro, 5 spd, nice, yah, thats not allot of miles, seems a clutch should go longer than 100K. You figure it was all the down shifting of the PO which caused the excissave ware then? Replacing the flex disc (s?) and ctr bearing isn't a big deal, just be sure and mark that drive shaft

I thought everybody downshifted. Never really thought about the whole "brakes are cheaper" thing, but you've got a point there.

hehe, you think 100k is a little for a clutch? my first car was a '99 nissan altima manual. i needed a new clutch at 54k!! ya i am not proud of my early driving, and love the "getting there happy and in style" style i have come to enjoy with my 300D.

I think the "brakes are cheaper" thing is a bunch of crap. The flex discs in that car are more than likely the original and would show that kind of wear regardless. Downshifting when done properly will not only save a little on brakes but is actually much safer way to drive.
