So there's one catch to the exploder rims. Seriously, the hubs on an Exploder are a hair smaller than the XJ. It's so close, if you bolt them on, you will be pressing them on like your wheel studs, and fight hell getting them off! I used a dye grinder to open them up till they slide all the way on. It's not hard, but work it in full circles so you don't imbalance them. You can tell where you've worn through the clearcoat to keep track of where you've been. The front ones are the issue, the back will go on with no grinding. But do all four so you can rotate your tires.
