Vauxhall brake upgrade

I was wondering if anyone could clear this up for me I want to upgrade my brakes to 280mm and have seen that you can use Vauxhall calipars does anyone know the Vauxhall they are fitted to. I have seen other posts but they just give models I am after the year and trim level or an oe part number is anyone has that thanks dan 

Afraid I cannot help with part no,s but when I tried this conversion some time ago I found the pads overhang the discs by a few mm, might not cause any issues but it put me of using them.

Just checking I presume the carriers from the Vauxhall are needed? What bolts are used ? Also any idea if they will work with 14" wheels? I have g60 brakes up front but I'm fitting Pirelli ps 14" so have to change them

calipers and carriers plus pads and flexi from vauxhaull, vw discs. you need sleeves for the carrier holes, or bolts with a shoulder as vaux bolts are thicker than mk1 versions
