I have just fitted these to my NA XR6 and they do work good. I have got the DBA 4504 at the fronts and 4505 at the back. The pedal feel is much better and they do stop good. I havent had any fade yet but mind you I am still yet to give them a very hard few constant braking sessions. I feel much more confident with late braking now. I have got them with Ferodo pads all around from autobhan when they had the 20% off 3 weekends ago for $800. I dont think they would hold up as good as the PBR kit but if you are not gonna do any track days or anything, I recommend the DBAs. I will post up some photos as soon as I can. <{POST_SNAPBACK}> Thanks for the info, and yes, please post some pics up, I have a guy that will get me them cheaper than $800 but not a great deal cheaper, and yeah I dont intend on doing track days, I just want something that gets rid of the shudder once and for all.
