My Xg350 Brake Upgrade
1. Does this apply to the RD1 aswell?
2. Is it safe to leave the retainer screws out of the disc/hub after reinstalling the wheel?
3. Anybody with ABS done this install yet? Does it link up and operate okay?
4. I want to do the rear aswell to match, would the same R1 Kia rotor and XG350 caliper fit?
5. How bad is the inertia effect from the heavier disc?
6. What exactly are these two part numbers for? Front & Rear calipers or XG350 & XG300 calipers?
I have phoned my Hyundai dealer and they cant pick up those codes, are there any other calipers I can use?

Well you are in a whole different situation. You have captive hubs and would need to swap those out first. Then go with the front XG Calipers and the Kia Rotors. Search around for the non-captive swap
Cannot seem to find it through search.
Are the calipers from the BBK set on SFR the same? I already got the Kia rotors

The Xg350 is not populair here in Holland! Unable to find one
I need them pretty quick, so i'm getting desperate now. (Blizaga!?)

My calipers and pads are on the way to me, can anyone verify about the rotors? What set do I order for SURE? I see stuff saying Spectra, others saying Spectra 5, and others saying either.
I just want to get these ordered ASAP.
Also, do the rear spectra rotors work with our stock rear calipers? I'd rather replace the entire set of 4, so they look the same and aren't warped.

Im not sure on the rears but the spectra rotors should be it. Whatever was in the original post is correct because thats what I have and they work awesome. I was thinking about looking into the rears and doing the swap in back also. Havent got around to it at all though.
I got my pads and rotors from the GB we had. Im sure he will still give you a good deal. They are very nice.
