I looked into this when a friend of mine took on a project fitting C6 Z06 brakes on his Kappa.
The difference between 114.3 and 110 is 4.3 mm; divide that by two and the result is 2.15 mm, the needed distance a stock stud must be moved, obviously, outward. This will reduce the amount of the land of the hub flange and although 2.15 mm seems small, it's relatively significant to the premium real estate of a Kappa hub flange.
I cannot remember anymore the measurement of the knurl diameter of the stock stud but I know that ARP carries other lug studs with a smaller knurl. What does this mean ? This means with the smaller knurl diameter, the reduction in flange land can be minimized. The result of my calculation showed, if I'm not mistaken, the reduction of the flange land closer to 1 mm. I could accept this number more readily than 2.15 mm.
All it takes is to source the right studs (with smaller knurl diameter) and then have rotors and hubs drilled to 5x114.3. No need for a swap.
