You know, I understand everybody has an opinion, and on this forum it's accepted, even encouraged to express them. Then there are those who just can't help themselves.
Personalizing your car is your priviledge, but be aware, when ever you deviate from "stock" most puriest will immmediately jump on you for even entertaining such outrageous thoughts.
That being said, don't hesitate to experiment with new ideas. Especially when you're not alterating an "original" part that came on your car. How else would new ideas and parts ever get created?
I will tell you, changing my hood was the best mod I could have made, and I've never had a moments regret. I didn't do it because I didn't like the original hood strakes, I just wanted to make my car reflect the type of car I feel the Crossfire really is. When Chrysler decided to "water down" the unique Crossfire hood design by using it on an SUV, Pacifica, and even a "fleet" car Sebring, I had no problem making the change.
Some Crossfire owners love the small spoiler, some prefer the SRT style. Others long for a Startech design. Maybe a new even more exciting design may be floating around in your imagination.
I've thought about trying to come up with a custom spoiler, (and I've made several drawings) but I just haven't hit on anything that looks right to me. I'll be looking forward to seeing what you might come up with.
