Front brake discs for E36 325i

["Nick Pashley" <nickpashley@xxxxxxxxxxxxxxxx>]

Hello

My front brake discs on my E36 325i are warped/distorted.  I am not sure what
brand they are, but they were fitted approx. 20,000 miles ago by a non-BMW
garage, for the previous owner.

They are not particularly badly worn, and I face two options, do I get them
machined or do I buy a new pair?  If I buy a new pair, I face a number of
manufacturers, in order of price:
BMW
ATE
Zimmermann
Guttmann
CAR

Does anyone have any experience of these discs (except BMW of course)?  Any
recommendations?

TIA

Nick
