G60 Brake Interchange

[Kneale Brownson]

--
Thanks, Scott.  So what can I look at on my 200q20v that someone converted
to G60's prior to my ownership to determine what I could use to improve
brake performance?  It looks like the important part would be the
carrier???  Should I find a number on it that will confirm which type of
conversion was done (ie., did they install S4 G60's or 5Ktq G60's).  If I
have the S4 version, can I upgrade simply or am I looking at more
thousands?  What about reinstalling UFO's?
