never heard of this brand before, but looks to be well made, of course without having them in hand looks could be deceiving. http://cgi.ebay.com/ebaymotors/KIDO...d=p4506.c0.m245&_trkparms=65:16|39:1|240:1318
I wouldn't risk it. I haven't heard anything at all about them, but a quick google search makes them seem pretty shady. Though they are a brand new company. EDIT: it appears that they're all sold by one guy - Pat Chan, who lives in Hong Kong and drives a 99 Type-RA. He's the only representative I'm aware of.
There is a thread on iwsti about these calipers. http://www.iwsti.com/forums/gd-braking/141116-kido-brake-calipers.html
