What is everyone’s opinion of wide body flares?
I think like everything else on a car, if it has a good purpose I like them. But (IMO) the purpose of a flair is to cover a wide tire and a flair that doesn't include that is weird looking. I think a stock A-Body kind of has an "elephant on roller-skates" look due to the rear axle being too narrow for the car, and a flair without a tire filling it in would be similar, only worse.
I think the WB LX/LC cars are a perfect example. I don't care if the flair is molded in or not, but they did it right and put a proper tire under the flair. So for me, they look absolutely wicked. Mostly because they have a tire that proportionally makes the car look purposeful and aggressive.
The front of an A-Body is somewhat limiting and I think anything beyond a 275 might actually require a flair of some type to make it work without rubbing. Not sure if the rear would need a flair to match the look, but the car can take a pretty wide tire in the rear without having to even mini-tub it.
So, my opinion is; unless you plan to fill out the flair, I would leave them off and just drive it as is until you can fix it.
