I have had Bilstein HD's on my '01 Jetta for 400,000 miles. They pound like a fricken jackhammer on cracked/broken/seemed pavement. They are fairly durable, 200,000 before replacements, but they are harsh as shit. I tried the Bilstein T/C's, bagged out in 80K. A much more compliant ride though.
Too much is just barely enough.....
