    coupe or hatch? Coupes seem to have more arch room than a hatch does, but 18's with a decent offset are your best bet. Not sure on max lowering, 30mm seems to be popular, though height adjustable coilovers will be the ultimate kit if you can afford it.

    will be able to get away will a slightly worse offset than a hatch then. 19's have been done by a few, not sure if arch mods are needed though, might just be a case of moving rear bumper bracket.

    you can go up to 19"s with a 40mm drop iirc.... probably with 225/35 or 30.you may have to do some arch work with 19s if the offset isnt right. I would stick to 18s" tho.

    do a search its been covered loads of times

    19s will need the rear bracket shaved and possibly rolled depending on offset/tyre size. 19s lowered 40mm (can go lower with a bit of arch work)

    18s lowered 60mm, had a few issues with rear bumper bracket, nothing an angle grinder doesn't fix.

    can't explain what offset is without trying to draw a picture lol but a good ET(offset) is as close to +49 as possible for vauxhalls. +37 is about the lowest you can go and even that might cause a few issues.

    *EDIT*
    The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types.

    Zero Offset

    The hub mounting surface is even with the centerline of the wheel.

    Positive

    The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front wheel drive cars and newer rear drive cars.

    Negative

    The hub mounting surface is toward the back or brake side of the wheels centerline. "Deep dish" wheels are typically a negative offset.

    If the offset of the wheel is not correct for the car, the handling can be adversely affected. When the width of the wheel changes, the offset also changes numerically. If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside. For most cars, this won't work correctly.

    offset won't affect the height of a car. The offset determins how far out the wheel sticks. The higher the number the further into the arch the wheel will sit. So like unique said as close to et49 as possible is best.
    If you had et35 chances are the wheel would be sticking out the arch a bit and would catch it everytime you go over a bump.
