Yes yes you do.
As bodged as a redrilled brake disc sounds a lot of thought/work has gone into it. Although I can't take 100% credit - I bought the disc + spacer pre-manufactured off a lad on the AX forum, but assembled and fitted the rest of the parts myself.
The whole thing is on AX front struts as standard 106/Saxo 3 stud struts have different mountings for their ATE calipers that aren't compatible with VTS/Bendix caliper bolt spacings.
