    Given you know the current wheel offset/tyre sizes, you could use this to see what difference the changes will make.
    This may provide some indication of likely clearance issues.
    (Spacers reduce offset so that an ET55 wheel with a 7mm spacer is effectively ET48)

    Righto - for a start, at the Front: You might need to retain the 7mm spacer or use a 5mm at the least, as a standard factory 19" rim for a Carrera 2 / 2S is either ET57 or ET55. The rubber is the same regardless at 235/35/19 so you could try a test fit at minimal cost to ensure that it won't foul the arch or liners when on full lock.
    Rear: ET67 is the correct offset for a standard car however, the 19" factory wheels for these models are 11" wide with an ET67 offset. The exception being the 11.5" 'Carrera Sport' wheels which are the same ET67, but have a 5mm spacer built-in to account for the additional 1/2".
    Given that your wheels are the full 12" I'd say you would need a spacer to offset this, but 15mm may be too much when you account for the larger 305/30/19 rubber required by the rim width, so a reduction to 10mm might be better.
