As others have said, flare can look great on these cars if the rest of it fits the look. For example, this Duster. He’s ruining a crown Vic (wide) front suspension and rear axle which obviously widened the track width considerably, so the flares were necessary.
And then there’s this 68 Dart being built by one of the head guys at SRT. It’s absolutely badass! These two cars are inspiration for what I plan to do with my first car, a ROUGH 75 Scamp that will be getting heavily modified.
