wheel bearing replacement interval?
I know they're must be threads on this...but my search came up with nothing (mobile site never works the same).
my friends with Miatas install new wheel bearings at LEAST once per year. I never run R-comps, but is this something I should be doing often as well? I only run R-S3s at track/auto-x. I do 2-3 a-X events per year and three track days, if I'm lucky. car has 115k miles on the chassis. I've owned the car less than a year, previous owner never tracked it.
can any of the track guys please chime in? thanks in advance.

IMO with the sealed bearing design on the evo, and the way its mounted, the typical shake method isn't as accurate as on other cars that have the replaceable bearings that you grease up. This is just my input from working on other typed of cars with bad wheel bearings and diagnosing my evo with bad wheel bearings.
There isn't really a service interval for bearings, and to really diagnose it you gotta tear into the car a little more and have some tools. The fsm has a few guidelines using endplay, but iirc you have to remove the axle out of the bearing. I had to remove the complete bearing/hub assembly out of the car and spin it by hand, then and only then I could feel, and hear the wear on the bearing. I posted a thread with a video on it a while ago. Imo, if you haven't replaced them yet and your at 115k miles and you track it, then its not a bad idea to replace them sometime in the near future. If they aren't noisy or bad at the very least you will reduce some rolling resistance with a fresh set of wheel bearings.

somethings not rt with the info from your buds.. Think about it, if the bearings needed replacing they would be on the basic maintenance record to be serviced at some interval--, 10k, 20k, 30k and thats not the case. What are your midas buddies driving and are you sure they are talking not repacking bearings once a year for service on something other then an EVO? Just asking because if you got 100k out of your bearings under normal driving, then it would take more then an AX to cause premature wear of roughly 10x. They are big *** sealed bearings.

also: I think most of us are beyond routine scheduled maintenance. we are always replacing all kinds of stuff most people would never consider. lol
I could see wheel bearing being one of them.
considering my mileage, I'd like to replace all...just hoping I don't need to for another 50k miles, or so. they are quite expensive..

A new set should last you for another 50k.
