yeah, the wheels have different areas for different reasons. However, saying that, I dont think i would use these for drifting. I dont drift (well.. maybe once or twice a year... lol). These tires outside edge tread actually are slightly higher than the inside edge to give more support during cornering. Maybe they would work better? No idea..
But overall, I like the look, and I've been using Good Year ever since my Uniroyals gave out on a corner in my 80 Celica (doing 80 in a 30 zone, met up with a hairpin curve... the tires didn't even squeak... the car however was a right-off). No seatbelts, just 2 young and foolish guys looking startled as the car went head on for a tree and a rock. Divine intervention wins the day!
