No need to lug a spindle and all around..all you need is the rotor and a few studs (or the hub if it's handy) to locate it in the wheel.

Just lay the wheel upside down, and lay the rotor on it with a few studs to center it, and you can take some measurements. (You may need to tilt it up some to measure further towards the center of the rotor if the caliper is going to be in contact with the spokes of the wheel in that area..depending on wheel shape) If you already had a caliper of course you can try that, but it sounded like you hadn't got those yet?


His stuff is pretty much all china but I suppose the price is cheap.
