Track Car Parts Replacement Program
Hey,
This post got me thinking https://www.miataturbo.net/wheels-ti...8/#post1393214
I come from racing where we changed certain parts routinely because we knew it was risking a DNF not to do so.
Assuming full sized road course, 150-200 UTQG tire, how often would you replace:
Ball joints - ? hours
Front Hubs - ? hours
Rear Hubs - ? hours
check Sub frames - ? hours
check Control arms - ? hours
Assuming full sized road course, 50-100 UTQG tire, how often would you replace:
Ball joints - ? hours
Front Hubs - ? hours
Rear Hubs - ? hours
check Sub frames - ? hours
check Control arms - ? hours
What other parts should be considered for programmed replacement or careful checking (crack test or visual inspection) and after how many hours? I guess wheels should be in there...what else?
Of course there are an almost infinite number variables, but this forum has a lot of experienced track racers that it would be great to hear from. Might also reduce the number of posts in the hub failure thread...(?)
Cheers.

subscribed for thoughts and anyone else's process..........my contribution is that i tend to replace when failing or gut instinct....stories of failing hubs etc. not withstanding.
Biggest issue here is that we tend to own mx5 / miata's for reduced cost reasons....a pro active maintenance process is probably a step beyond our reach....unless by profession eg. Emilio, Savington etc.
I might be wrong and am interested to hear otherwise.
I do try and keep spares on hand.

Well, it's obvious. All these parts last SOO long on a miata, no one has ever even bothered with calculating out a life-span for each. 
Like mentioned before, we would really be leaning on racing shops(949, TSE, OPM, LRR, etc) for this info. I think several of us shade-tree mechanics(like myself) usually run across failing components in our typical pre/post-race checks and replace them.
TL;DR - I wish I had some data to offer.
