I have to question this, simply due to the fact that my 02 WRX had
pretty bad cold shudder right out of the box; not even 5000 miles on it
and it was happening. When I got the clutch replaced, the mechanic
could still see the white labeling on the face of the plate. It had
nearly no wear on it at all.
The problem (at least in terms of the WRX) is documented in a service
note, which I have at home; the recommended solution is a heavier
I got the clutch replaced, and the throw bearing gave out on the new
clutch within 2 days. I was stranded and needed a tow.
Got another clutch put in, and afterwards, the car started making some
very odd noises at about 4000 rpm. The mechanic spent the next week
troubleshooting the problem, pulling the entire rear end apart (because
that's where the noise was coming from). Never occurred to him to
address what was recently changed - the clutch. He finally did so, and
the problem went away. So, for a WRX that now has 40,000 km on it, this
is my 4th clutch.
This is basically just a rant, but I also wish to suggest that in my
experience there were _definitely_
manufacturing issues with the clutch
hardware, and I expect that this piece of kit may or may not be
effective, depending on the root cause of the problem.
