the bolt pattern is the same but the offset is higher - but it still might fit. test fit one on the back and make sure the tire doesn't touch the strut at all. make sure that once the lugnuts are tight you can freely spin the wheel (obviously with parking brake disengaged). they are also a little taller tire, so your speedo will be off a hair, but it's pretty trivial. get the tire size from your friend and google the "miata tire size calculator" to see just how far off your speedo will be.
btw - i thought my 98 had low mileage with only 126k on it...
