The OE Honda S2000 rear wheel hubs are unfortunately a weak point when combined with track use and meaty tire setups:
The primary failure point is from the lightening cut-outs on the backside of an already thin hub flange. Karcepts S2000 Rear Hubs are filled in solid and built with an increased flange thickness. Rotor retention screw holes have also been eliminated. These 3 simple geometric adjustments have reduced stresses by two-fold over the OE Honda units. Along with design optimization, Karcepts hubs are machined from chromoly steel and heat treated for an even greater endurance limit.
