Modern side mirrors what do you think

I think I'd have to see them on the car. Most of the aftermarket mirrors I've seen used on old Mopars look like crap, but they're also usually just really cheap crappy mirrors so they look even more out of place. I think they'd probably be better off painted body color. I don't have a problem with carbon fiber on these cars at all, but if the mirrors are the only thing that's carbon fiber it might look a little weird. If you had other components that were carbon fiber I think it would work better.

As far as visibility goes, I'm pretty sure there's almost nothing you could do that would make the visibility out of the mirrors worse than stock, outside of not running mirrors at all.
