Hey This is my first time owning a rolla. I have previously owned Commodores so I have many parts lying around.. One thing I have noticed is my AE93 doesn't pull up too well, even with new rotors and pads, So what I was thinking was, why not retrofit a set of cheap VT calipers ($40 for the pair) and rotors to suit (get DBA to make me up a set of 4x100 rotors to fit).. By the looks of it, it seems like a cheap way to get some big twin piston brakes.. Has anyone ever looked into doing similar? Cheers Jack
