I think there's a lot of biases both ways in this poll. It really starts with the title itself where anyone who tunes an import is a ricer. I've seen plenty of people behind the wheels of V8s that I'd consider just as much of a ricer. And I've seen some very well done 4 bangers that'd put most V8s to shame.
Also, it seems a lot of people want to equate performance to being able to accelerate hard in a straight line. There's other aspects to performance that just get over looked. Handling. Whether it be weight distubution, skid pad numbers or braking abilities, these all play into making a car go fast on a real track.
