Steve,
The biggest daily problem is turning very sharp into a parking space
at slow speed and having the tires scrub on the pavement. At high
to moderate speed it slows you down in a fairly sharp corner very
quickly. I tried steering with the gas at a few autocross meets.
There is a fixed amount of traction available, which if you apply
too much vector force ahead, (hit the power) plus the vector force
that is turning you, you exceed the traction of the rear tires and
suddenly have major oversteer and spin out backwards. I did it
a few times. A sway bar on the rear made it much worse.
So I took that off after one day of trying it.
