    Although the top spec Mk2s share the same size discs as 4stud Mk4s (256mm x 24mm)

    they have a different part number which would suggest they wont fit...

    however the discs would be interchangeable on Vectra 4 studs, Astra Mk3, Cav and a few others so maybe they may fit.... Im sure seeing as they have different PNs then they wont fit - - - but who knows!

    Why would you want to anyway? If you're upgrading the brakes on a 1.7DTi you'd be wanting to go to at least the 280mm jobs off the 1.8/2.2/2.0DTi which means different knuckles, calipers, discs and pads.

    considering we're talkin about £500 tops for the 308 kit I think Mel was looking at cheap alternatives and maybe had some GTE stoppies lying around hence the question.

    If this is the reasion, as I said earlier - the dimensions are the same so they might fit.... cant guarantee it though.

    The disc size will be the same but the caliper design and more importantly the mounting of the caliper on the hub which has the integral caliper carrier is totally different.

    Have a look at this for an alternative option

    http://www.astraownersclub.com/vb/sh...d.php?t=112467

    I have also been wondering if 288 discs will fit as when I looked at the caliper carrier I could see that there was a few mm gap to possibly allow a bigger disk. Would need to check the details and P/N for this. It would mean a reduction in cost for doing this conversion.

    I also considered doing some research to find out if the mountings from 288mm V6 brakes would be the same for the Astra G 280mm brakes. But never got that far. May be worth looking into though as if the V6 caliper carrier mounting is the same than i would imaging that you could take possibly use that setup with 4-stud 288mm discs - BUT DON'T HOLD ME TO THAT - you would need to get them or get a look at someones brake setup to be sure.

    EDIT: I just found this..... The P/N for the caliper are the same from the Vectra 288mm discs BUT NOT SURE about the caliper carriers.

    You could then look at these...

    Here is what I used for the conversion on the good ladies SXi

    5-stud Hub steering knuckles
    calipers and carriers from a 280mm 5-stud (though all you would change if you wanted the 308 brakes are the carriers
    brake pads from the 280/308mm brakes (any Coupe/Hatch that has 5-stud)
    a set of 280mm 4-stud discs
    mounting bolts to mount the caliper carriers to the hub
    the anti-rattle caliper springs
    some brake fluid to bleed the system
    a socket for the hub nut

    Its always the way though ain't it.... You start withe wanting something just to make it a bit better then the bug bites...

    You can stilll go for a big brake convesion 280's will fit under 15's and 308's should fit under 16's, well they so on the late spec alloys, but that debate has went on before about the early spec ones

    I may just take one of the SXi rims off the good ladies car and sit it on my car just to see.
