whats the DBA part number. I might be interested in them given the dimensions. Are they blanks or have they been redrilled to suit toyota or? drilled and slotted?
DBA haven't updated their catalogue yet, but if you look up the discs for the Adventra, they are similar except they are 336mm OD, 32mm thick, radially vaned, radially slotted and these are actually made by AP racing for HSV.
The centrebore and PCD of the discs is the same as the Adventra.
