Thank you for your support Neil! If Tirerack ever has a lower delivered price (unit price + shipping) let us know. We won't be beat.
Aggie, it will really depend on the tire size you want to run.
Assuming you are running 17" stock wheels without spacers here's some numbers to consider.
17x9 0mm offset = 5" Backspace and 5" front space
17x7.5 +44mm offset = 6" backspace and 2.5" Front space
This translates to.....
The 17x9 will be pushed out 2.5" closer to your fenders than where your stock wheels sit now.
The 17x9 will be pushed out 1" further away from your control arms and suspension.
