X-Tracker vs base?
I'm not the one with all the input on these but the gyst of it is that the X-tracker survives a lot more abuse from racing slicks and heavy braking without having to be replaced for a longer period of time.
I have seen some racers argue that the X-tracker is a must for the rear but that a lesser piece can be used in the front for track cars.
For a street car I don't believe it will be necessary. We're just not abusing the car as hard or for nearly as consistently long as on a track no matter how aggressive we think we are being.

If you don't autox or track you'll probably be fine with basic bearings. If you don't want to have to do the job again I'd probably spring for at least the MPI bearings. Replace them in pairs though. The zr1 style flanges are a little thicker.
