MR-S Rear Hub Discussion
Learned something interesting tonight doing a little research on hubs. Did you know that the mr2 spyder rear hubs have the SAME 26ct spline and diameter, SAME bearing race id diameter (40mm) with .07" thicker flange and overall beefier flange base? Differences are .2" longer spline length in the spyder, .09" longer bearing depth on spyder and .3" forward axle position on the miata hub... this is a perfect candidate to massage in a lathe and possibly offer a beefier alternative to the oem miata hubs. Who wants to try? Yea/nay/nof'inway? It'll be another 5yrs of I try it, lol
Btw, this new spyder hub from autozone was only $20 to play with.
I cut the race off to get the .09" length difference between the 2

What year MR2?
Any idea if the front hubs are similar enough to modify and use? Or if they're beefier enough for it to be worth it?
If there is anyone in the Seattle area willing to do the machining on them for me for a reasonable price, I'll give them a shot, especially for only $20 at autozone compared to like $55 I spent on new rears.

That's what sparked my interest in looking at the rear hubs off the spyder. I didn't know that the rear hubs were now an option with the Keislers. I have Sav's Keisler drop spindles and the front spyder hub it uses is certainly more robust - but there's no way it'll fit or be modified to work with the oe spindles for the guy asking...
Dropping hubs and oe spindle and axle to my machinist today to investigate further.

I will say this - like the miata hubs, I'd only buy oem hubs to mod (at @$170ish ea) unless actual lab testing says the aftermarket hubs are just as strong. I wouldn't mind watching something get crushed... best test would be lateral oscillation vs straight one-way force... which one of my sciencey customers can do.

I ordered a couple toyota hubs to turn for my car... shouldn't be much if any differences dimensionally between them and the cheap $20 hubs. Why did they put 4 extra holes in the hub?

I really think the only downside to this hub, after machining, will be a slight loss in overall spline length in the hub. Nothing I'd worry about unless I was drag racing with monster power to strip them out...
