i had the exact same setup
except my rear offset was 45mm with the same tire size and was lowered on HR sport suspension
i put 5mm spacers (effective offset 40mm) after i rolled the fenders, it still rubbed from time to time,
so, can you imagine 33mm offset?
like i said, you may get away with it on stock height, but big rims and narrow tires with a large wheel gap to fender will not look good, especially with the tire/rim out past the fender, so a narrower tire (stretched) and camber work will be necessary if you want to lower it.
