I've owned drifted on Megan streets, PBM's, drifted on Stance GR+'s in a friends car, and I'll tell you, of all of those (not like it's that many), I would go with PBM all day. $1000 shipped to your door, they ride nice for daily, nice control while drifting, that, and they are designed for lowered cars, and drifting. Almost tailor made.
I don't see why anyone wouldn't buy them, to me, they're the perfect entry level coil, and perform way better than most any $1000 coil set up.
