Should have loads of room on your hatch for 18's mate. I've got 18's and there's tons of room left

Rule of thumb.

Increase wheel diameter, decrease tyre wall height in proportion.

BUT the PCD (the distance between the holes in the wheel hub (or the bore size)) may be different on the GT1's if they came off an Hatch STi, so will not fit.

look up a rolling radius calculator, when you increase the alloy size, you ideally choose a tyre profile that means the overall rolling radius is not affected too much.

See here too, lists the wheel specs and tyre sizes with images. Although this doesn't take into account any arch work, what suspension they're on etc
