Re: E36 M3 Rotors

[Sam Choi <choi.192@xxxxxxx>]

Thanks to all who replied (Jim Bassett, Karl Zemlin, John A. Virnig, 
Ron Buchalski, JUSTIN GERRY).

The consensus appears to be that the diagnosis by my dealer's 
mechanic is a crock.  Sure rotors can rust but that does not itself 
explain the shimmying.

To review, my wheel shimmies and my brakes pulse under braking.  I 
have a 97 M3 with 18K miles that is not a daily driver.  It's endured 
4 tracks sessions (about 2 a season) and 1 autocross (and I'm careful 
about not using the parking brake at these events).  I keep a garaged 
and Columbus is sometimes humid in the summer, but not usually so.

It does seem that the rotors are warped, though I can't explain why. 
I'm going to a 3rd party mechanic for a 2nd opinion and to do the 
work.

Cheers,
Sam
