if they are non/vaux wheels best check what studs are needed then,Ad1.8GLS said:for the record the alloy wheel's i have just got today are non vauxhall alloys.
i am not sure if my astra has ever had alloy's fitted to it
It's the easiest but it's not the best solution. Converting to 5 studs has a lot of advantages, most of which is the much bigger brakes the 5 stud has as standard, secondly 5 studs are ABS and he could always try and retro fit a ABS setup as he'll probably already have the hubs. He can convert to the 308mm setup off a GSi and that has a LOT of stopping power and looks much nicer filling the wheels. And lastly he'll have rear discs and get rid of those unsightly rear drums which don't look great behind big alloys.Andy R said:that makes most sense to me tbh,

Fair point Andy but the clue was in his first post. You can get 4 stud Astras with ABS and drums, I've just sold a rear beam to convert one to rear discs, some come with rear discs as standard however I've NEVER seen an ABS Astra that came with steel wheels, they all get alloys as standard as the spec level for getting rear discs and ABS would mean alloys were fitted as standard.Andy R said:also just because it is 4 stud atm doesnt mean it wont have rear discs and ABS already,
i would imagine if wouldnt have either or maybe just ABS but some 4 stud astras have both
