[W126 Coupe] ET Ranges

[Vince]

Hello folks,

I have purchased a set of Gil Racings spacers, 25 mm in thickness, for my
coupe in anticipation of getting a set of stock MB wheels.  Considering the
thickness of the spacers, what ET range can I safely fit to my car?  I am
searching for a set of 17 by at least 8 inch wheels.  Thanks in advance for
your help!

P.S. The spacers can be seen at www.gilracing.com.  The quality is awesome,
much, much better than the H&R spacers.
