I should try drifting the bird. My rear camber is maxed out at 0* which is a lot for my platform. Im on 285s with plenty of power. I would really love to ride with one of you nuts sometime. That would be a blast!
As for stretched tires. It’s another bling factor baller thing. like I have sooo much money I don’t care if I curb a thousand dollar wheel and that my fender filets my side wall on every expansion joint. Hell, I don’t even care the the paint is completely removed from my inner fenders and quarters. I wont rust cause the tire will polish it clean again tomorrow. But really it’s a trend.
10 years ago every civic, accord, and neon had a huge fiber glass or sheet metal 3 element spoiler and a DC knock off muffler clamped on. I feel stretched tires have a lot more taste than APC windshield banners and body kits with sheet rock screws.
As for performance, I can see how a little bit of stretch could make a 45 series tire feel and work like a 40 or 35 series. Obviously it works for the drift guys. I’m not sure what you sideways individuals run for tire pressure but I assume a 185/75R14 on a 5 inch rim would probably be on the side wall the way you guys drive and may even come off the bead. For racing tho. You dont see Formula 1 cars on stretched tires. Though that is a apples to oranges comparison.
