That is correct. The EC-7's do come in an 18x9" ET31 size and the ARC-8's do come in a 17x9" ET30 size but the ARC-8 in 18" at this time only comes in at an 18x9" ET42 size which does require a wheel spacer in the front when using 255 and wider front tires. The ET30 offset is also ideal in the rear of your car where you would not need any wheel spacers at all unless you were looking for a slightly more aggressive and flush wheel fitment.
