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

Do you need lathe work? I can play...

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.

Spyder

Keisler drop spindles have an option to use these instead of garbage Miata units. I'd be in for some modified MR-S units, seems more in scope than drop spindles for me.

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'd be pretty wet if i could end up with MR-S rears and V8R fronts on oem spindles.

Am I to take it that you'll be up for beta testing a set of rears after signing a release of liability form :)

Sure, but i don't drive my car much.

Hrmmm, I could use those MR-S rear hubs. Maybe I'll bug Keisler about them. And by maybe I mean I'm messaging him now.

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 love this bar.

Worthless trash post so i can get notifications.

And that concludes my useless post to get notifications.

Typing is easier than clicking.

Have lathe......and ordered part to play with. This will go well with the front hub solution I'm experimenting with.

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?

4x114.3 lug pattern maybe?

Weight reduction

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...
