can any 1 tell me what would be needed to drop my car. i will be getting a set of 18s soon and would there need to be any work needed to the arcs. once they r on how much will i be able lower my car without the wheels rubbing on the arcs

if u get the correct offset wheels then u can lower ur car upto 60mm without scrubbing...
i have 80mm drop on 16s and have never experience any scrubbing why because the wheels are the correct offset for my car...
its all down to the wheel offset matey

How do you work out the offset to your car

right mk 4's........you want as with most vauxhalls as near to possible ET 49 but with the mk 4 you can go anywhere between ET 40-49.....if you want 18's on and yyou want it low...get ET 45-49 7.5 x 18 and you should be able to get a 60mm drop at the front and 40/50mm at the rear with no scrubbing at all.

I have got 7.5 x 19's ET 42 droped 60/40 but i had to have the arches rolled and a bumper mount changed slightly but they dont catch.

More info on wheels on www.astra-sport.co.uk as lots of mk 4 owners are changing wheels at the moment.
