Under glow can look cool sometimes... but it's just too ricey and played out for me. I'm considering putting lights in my grille to shine a glow on my intercooler though, but I don't think there's room.
Big spoilers/wings... hit or miss IMO. The best is seeing them on FWD cars lol, just completely stupid. Even on a stock mustang, not for me. On a high powered car I feel like you can get away with it a little more, I've thought about it myself.
Tire lettering I actually like, but too much work/expense.
Fake scoops/vents, completely stupid IMO, theyre actually just going to impede airflow lol
Carbon fiber, small portions of it are ok, but overall it's just not my taste especially when its the entire interior. The only piece I really like in carbon fiber is some of the steering wheels available.
I mean I’ll take carbon fiber anything on the outside. That actually serves as a weight reduction purpose. The fake stick on air vents are hilarious. And Mexicans love them around here lol
