Go wing or No Go wing
Well, yes. It isn't just the rice burners that I'm thinking of in that adding a coffee can muffler and a pissing Calvin sticker doesn't make your mom's Honda any faster. And neither does festooning one's classic car in clownish accessories from the JC Whitney catalog. But more than that I'm thinking about real supercars - Ferrari, Bugatti, etc. Those cars need actual rear downforce with the aid of a wing. Now that that has become common gearhead knowledge, any car you see with a wing that isn't a million-dollar supercar designed to set record lap times around the Nurburgring, it obviously doesn't need the wing.
So every time you see a sub-150mph car with a rear wing it's hard not to think, "Yeah, buddy. That Dodge Ares sure needs down force. Uh huh. Way to keep it subtle."
I mean, I love my muscle cars as much as the next guy, but let's be honest about the downforce issue. My 'Cuda has 300hp - but lack of downforce doesn't really present an issue.
All of which, of course, is my own humble opinion.
