Working on finding a combination of brake parts that will fit on my car, which is an R31 Skyline with S13 knuckles. Z32 calipers wouldn't fit under the wheel setup that I have, and I didn't want to change that, so I decided to use J30 calipers. I wasn't able to find any "performance" oriented J30 rotors, so after comparing the specs, I bought some Z32 rotors from EBC. They're 2mm thicker and about half a mm taller than the specs I found for OEM J30 rotors. Has anyone else tried this combination? Were there any clearance issues? I did a lot of searching before I bought them, but wasn't able to find anything, and although I haven't bolted up everything tightly yet (need shorter caliper bolts), it LOOKS like I shouldn't have any issues.
