so after some digging, form my 1.5T insignia B , the front brake disc size is 300mm vented of course , but it seems its only this model that has the 300mm disc all the others seem to have either 296 or 321MM? does that sound right ? as the choice seems limited if i want a drilled one, i would like a EBC ultimax version but they don't seem to do 300mm 
looks like a black diamond drill set
