Napkin math/free body diagram of stresses in the hub flange:  The class's obsession with lowest possible offset/widest possible track width, and the HEIGHT of the tire, is likely doing more harm than the difference in "stickiness" between RA-1s and Hoosiers.  The added unpsrung weight isn't helping, either.  I actually think the "stickiness" is probably the least important of the four, for this particular failure.

 

Long-term, SM would benefit from less tire, not more.

Bringing up an old thread here...

 

 

I think I heard there were three or four rear hub failures in the 2013 25hr...  Seems to me that these parts are starting to see an rise in failure as grip increases and they get more miles on them (some are as much as 24yrs old).

 

For Non-SM racing: Does anyone know of a machine shop or manufacture making custom rear hubs?  5-Lug variety?  Info on anyone who is marketing them would be greatly appreciated.

 

Try Wilwood, Coleman Racing maybe Howe also

I may be wrong...but i thought someone told me 949 has a replacement?

I hope not, their car was one that had a failure

 

The 997 GT3 was just avoiding this loose tire that fell off a Miata (Not Pictured)

I call BS, that part is actually the Direkt Schalt Getriebe Hinter Axle Optimality-Insuring Confabulator Bearing, and it flew out from under the ass-end of that SuperBeetle 2 seconds before that pic was taken.

 

You can't fool me, Mueller!
