[s-cars] Re: anybody have any insight on putting Boxter calipers

[Dave Forgie]

Greg: Okay, I may stand corrected.  IF I had been able to get into the BIRA
website (which I haven't been able to for some time - especially the members
only portion), I might have been able to give a more intelligent answer.

The question was asked by a person who had previously asked about using
used/rebuilt early run Viper calipers which, reportedly, are a Brembo
caliper.

Bottomline: If I had it to do over again, I would go for System 3 IF (and
only IF), I could run 16" OEM wheels without spacers.  I still don't know if
that is possible.
