Hello, I have some spacers I just got but wont fit the wheels. They are going on a Lexus LS460. The spacers mount up to the hub, the lug nuts thread on and stock wheels mount fine. But I got them to put aftermarket wheels and they wont mount. Even though the wheels mount perfectly fine to the stock hub. I was thinking of freezing the spacer and heating up the wheel but that might put me in bigger trouble if I need to take the wheel off. Any suggestions? Thank you kindly!
