Re: 6in or 8in?

As many have mentioned it all comes out in the wash depending on gearing.

The KoP wheels have a coefficient of friction of 0.9, compared to 1.2/1.3 for the plaction wheels with wedgetop/roughtop tread.

I am a fan of keeping the CG low, but for the purposes of high-speed impacts you want to keep your CG inside the bumper zone, which happens to be pretty darn low this year: 1" to 7" IIRC.

FWIW we are planning on using 6wd with 6" plaction in the middle where most of the grip is generated, and 2007 FIRST wheels on the corners (you can buy them from AM). They are a softer rubber than the 2011 KoP wheel so they have a CoF of 1.
