Not round. Out of balance. Crock of shit. But so are all these new drums these days. Shit! You should order 6-8 pieces and keep the best pair you find and send the rest back! That's all you can do if you want to leave the drums in your car. You can find and sell old models from the USA at a junkyard. I bought new drums for GM and Ford. These new drums are junk! It doesn't matter who you buy from! They all seem to be from the same China!
