Problem you've got is the small rotors, the Corsa C has the same size rotors front and rear, and even for my car I felt they were dodgy at best. 5 stud Astras have 280mm front and 264mm rear. Would be better than the 4 stud setup, but seeing as you've just put new rims on, you may not want to change the stud pattern. Or you can get the 280mm (or 308mm) setup, redrill the rotors to 4x100 and have spigot rings made up.
