This is usually not the fastest way around on a hard surface, when dealing
with a under powered car. The adhesion differential is to drastic. It's
to easy to blow it, and get to much oversteer which scrubs speed and
requires more acceleration to get going again, ie: slower times. Keeping
all four wheels in contact with the ground will not only give you more
control, but provide a consistant result and consistantly faster times.
The trick is to keep the car on the edge, not over it. If you have ever
been to nationals, or seen a fast driver of an underpowered car, you will
most likely NOT see any oversteer techinques used. Less trailing throttle
and trail braking can optain the same "minimize understeer" effect while
still maintaining more predicable control. It isn't as much fun as
swinging the tail ;-), but it will be faster on the average. Now, on a
loose surface (gravel, dirt) the limits are so much lower and the delta
grip changes are smaller, which allows more time to "feel" and setup the
oversteer technique. This makes it easier to control and theirfore more
predicable and undoubtably the fastest way.

I found that downshifting during braking does the same thing (without the
locks). It's amazing how fast the car slows.

I found the car to be almost unsteerable with both diffs locked. It is
really noticable in snow. Do you ever run a video camera in your car
during your runs? I would love to see how you are achieving turn in this

Sounds fun! But it would be illegal to make that change and run in Solo II

Don't worry about me. I still think it's faster in the dry without the
