Thanks for the info! Won't get around to it probably until the Spring. Might just do them simultaneously when I do my rotors. But, I will certainly let you know what happens when I do.
BTW, sorry BoxsterRS....I kinda' highjacked your thread here. Good luck with your calipers and please post your results when you're done, especially pics from your autoshow in P.R. Would definitely like to see how you do and what you decide on.
