I like the big tail look, but this isn't a permanent part of your car, so you can always swap.
I had an aftermarket RS America wing, and it looked great in body color, Plus it bolted in through the grill opening. Big wings are bad ass. 964 wings are understated.
Wing, no wing, you put it on your car, and in a month you start thinking that it is the best looking, even is you weren't initially sure. It's an old Jedi mind trick that your brain will play with you. If it makes it easier to decide, you just want your car ''finished''.
For now.
