Differences in rotor/caliper 95-98?

[Prok0]

Just wondering if there is a difference in rotor size or calipers between 95-98 model year 240...
I just converted my 96 S14 to 5 lug and I got some front 5 lug rotors off a friend with a 98, and the rotor is like 3-4mm taller, and as a result rubs the inside of the caliper..
So im just wondering what the deal is with that, I called up a friend who works at discount auto, and he said that the part number for the 95 and 98 SE rotors are all the same, but the caliper part numbers are different..
So im wondering... does anyone know for sure that there is a difference in the cailper that would accomodate the extra rotor height..
And why would the SE rotor be taller then the stock?

From what I've heard the Koukis are slightly larger, they're the same size as Zenki ABS calipers, but I've never verified it myself. I have both at the shop, if I remember it I'll measure them tommorrow.
