Re: 200 bucks for this!
I believe someone covere dthat under control in a spin. What i mean is
that with the dfinite understeer, there's less chance (as i understand
it), for a spin out. Your front wheel are far more likely to lose
traction first, if i understand the whole concept correctly.
However, i can't believe that people would rather lose steering control,
rather than have the back wheels go out a bit. :)
