Left front wheel failure, midcorner on Riverside at Buttonwillow Raceway!

2007 Honda S2000, intake/exhaust, aero

Wheel is a Forgestar F14, 17x10 +55. 14 track days total on various Southern California tracks. 6 days on Hankook RS3, 6 days on R888, and the last two days were on Bridgestone RE71R (which were giving me noticeably higher lateral loads).

Prior to my first day on RE71Rs, there were no visible cracks on the exterior of the spokes. I lazily ran my hand along the backside of the spokes, but obviously missed, well, a lot of cracks. The spoke that was cracked clean-through on the right-rear either cracked at that event (WSIR) or during this event at Buttonwillow. The front left may also have had a complete crack prior to or during the Buttonwillow event.

All wheels are eventually prone to this sort of failure, but some sooner than others. More comprehensive data on these wheels is available here: http://www.s2ki.com/s2000/topic/10726...

Also, if you want a chassis-mount wing for your S2000 that enables you to apparently drive the wheels off your car, let me know here: http://www.cgtechnic.com

I've put together a sort of debrief on this incident at S2ki, the permalink is right here!
