    from my question as to whether mk5 brakes would fit into a mk4, I was told mk5 vxr brakes (disc, unsure about pad upgrade) will fit onto a 5 stud mk4

    VXR brakes will fit, they are 322mm. Need calipers, carriers, discs, pads and hoses.

    if your running stock pads, maybe look at upgrading them for a short term solution. Unless you want proper stopping power, then you'll need a 4pot upgrade

    Personally Im saving for a 4-pot upgrade but in the meantime Im more than happy with my grooved 308mm and EBC Yellowstuff pads

    Front Discs cost £100
    Yellowstuff front pads cost £80
    Fresh fluid throughout and a set of braided hoses will have u more than happy

    VXR stoppies are a good upgrade but I wouldnt pay full retail price thats for sure....for just over a ton more u can get a nice 4-pot upgrade

    compared to standard turbo spec 308mm I dont rate the VXR setup personally

    It is afterall still a single piston caliper albeit with a slightly larger surface area of disc

    Your best bet personally would be new discs, uprated pads, braided hoses, fresh fluid throughout

    Ive give recommendations above so totally upto you if u think its worth persuing

    Heres the links if it helps you decide

    FRONT 308mm Grooved/Drilled/Combi Discs : http://cgi.ebay.co.uk/ASTRA-TURBO-GSi-Drilled-Grooved-Brake-Discs-FRONT-308mm_W0QQitemZ300226612908QQcmdZViewItemQQptZUK_C arsParts_Vehicles_CarParts_SM?hash=item30022661290 8&_trksid=p3286.c0.m14&_trkparms=72%3A1301|66%3A2| 65%3A12|39%3A1|240%3A1318

    Same discs as above but also rear discs : http://cgi.ebay.co.uk/VAUXHALL-ASTRA-TURBO-GROOVED-PERFORMANCE-BRAKE-DISCS_W0QQitemZ300256514335QQcmdZViewItemQQptZUK_C arsParts_Vehicles_CarParts_SM?hash=item30025651433 5&_trksid=p3286.c0.m14&_trkparms=72%3A1301|66%3A2| 65%3A12|39%3A1|240%3A1318

    EBC Yellowstuff Pads: (Front only) http://cgi.ebay.co.uk/DP41183-EBC-YELLOWSTUFF-BRAKE-PADS-ASTRA-ZAFIRA-TURBO_W0QQitemZ250353199621QQcmdZViewItemQQptZUK_C arsParts_Vehicles_CarParts_SM?hash=item25035319962 1&_trksid=p3286.c0.m14&_trkparms=72%3A1301|66%3A2| 65%3A12|39%3A1|240%3A1318

    Rear Pads - just use standard compound pads at approx £15 (check if Lucas (smooth) or Bosch (ridged) calipers)

    Braided Hoses - £70 for full 6 hose kit (2 front & 4 rear) Ive got a set of fronts for £30 delivered if ur interested

    If you front calipers have seen better days then a full rebuild of the seals for £25 should have them on top form again.
