Style 132s with 4.8iS kit...opinions needed!

[Carbon Schwarz]

A guy backed into me this week and damaged my front bumper. Thinking of paying the marginal difference above insurance to get the 4.8iS front bumper installed on my 2004, 4.4i. Couple of questions:

1. How will my 132s look against the 4.8 front bumper? I love those wheels and have no interest in changing them.
2. How ghetto will it look to only upgrade to the 4.8 front and not rear?
3. Is there anything I should be aware of when getting the bodyshop to order the 4.8 kit? That is, will I encounter wheel arch discrepencies or grill color differences, etc?
4. Lastly, do the rear 4.8 bumper add-ons have the same part numbers as the 4.6?

Thanks in advance,
