    re drilling sounds dangerous mate


    but then again i've just looked at ur car, and if u do a 5 stud conversion, u'l have to loose the wheels.
    Observe the masses and do the opposite

    Personally, if i was you and wanted 308's that badly i'd get a 5 stud conversionm then go with VXR brakes

    No longer owns an Astra


    Bye bye VXR Castle Combe Edition - because it's done more laps of Castle Combe than most Bergs have of the Ring

    LMF suppy the whole kit for a 308mm 4-sdtud upgrade usign re-srilled 5-stud disks. Many have used this kit and even the Corsa/Nova owners use Vectra 288mm re-drilled discs.

    Check out LMF site.

    Also for somthing different you could copy me and do a 280 mm 4-stud conversion. I did this on the missus Astra G SXi 4-stud. (Ohh and I have copy right so send me a small fee )

    I have 308's redrilled to 4 stud and have no issues at all, even under the heavy breaking I have done there is no signs of cracking ect.

    just putting a wheel on becomes a Art form

    I personally can not see the point in spending extra on drilled and groved as it dont make a huge differance espcially on a smaller engined astra. To improve braking you need bigger disks, and a good brake pad. I have 888 pads that seem to be sound

    Brett,

    You are absoutely correct in saying that drilled and groved discs does not have much difference on smaller engine but I think people do that for aesthetics pursposes. . No dought about it if you put replace your stock disc and change it to 308's, your car will look absolutely sporty. Just like other accessories we put in our car, it is mostly for aesthetic pusposes.

    My car currently have a stock size 15" rims. I was advised that I have to change my rims into 17"s before I could change my disc into 308's...
