Greg: Already running 4.10 gears with a 32x14 tire. I'm probably going to try a 33 if it clears ok, but that will only lower my trap rpm to 7150-7200. Trying to use what I already have.
According to a formula I found, the kinetic energy in Parts increases at the square of the speed. 7200 rpm to 7500 rpm would be an increase of about 8 percent.
Add to that the energy and resistance to change in direction and control surge of the spring increases due to kinetic energy and that increases stress to another level .
