where can i get, and how much can i expect to spend, on gsx calipers? the gsx calipers on the rear are the same as ours, right? also, the vr-4 calipers are bigger than those found on the gsx; am i correct? how much modifying is required to fit vr-4 calipers on our cars? is it not worth the hassle and the gsx brake upgrade the way to go? just read an archived article on speedoptions.com where the guy upgraded his calipers to the 2-piston setup of the gsx and installed the aem big brake kit: http://www.speedoptions.com/news_headline.asp?aID=278&ref=search&v=1&pg=0
