Nut shell AutoX tips. (But I've never done
1. Turn OVER the cones....not at them. Set up early for going around the
cones and plan ahead two or more cones so that you've moved into decent jockeying
position when you have to (usually) change direction after a string of cones.
1a. Stay in 2nd or third gear to redline. (In otherwords) shift when needed,
not all the time (speed related) 3rds good to 80 MPH or so. Forget fourth
unless your at an airport...........you MAY never get out of 2nd.
2. Plan ahead of where you are..this getts incorporated into Number 1
3. Avant Understeering? If there is enough room lift throttle to
(oversteer) after turn in / in Mid turn.....just applying throttle into a turn will push
the front end out and away from your goal (over a certain tire traction speed
like 25MPH).........that's understeering.
To quantify # 3 (like 25MPH) take the Avant to a parking lot, do a constant
radius circle of like 100ft or so and go around under light throttle
(increasing speed slowly) until the tires squeal............Note the MPH mentally.
Then do 200ft radius "orbits"
then 300ft......match those mental squealing speeds to the turns your line
will allow on the auto X course.
Speeds along those radius, higher than those parking lot "tests" will respond
to lift throttle oversteering during the event........OTHERWISE, you'll have
too much grip to break tires free.
4. Smooth wheel transitions. Turn in steering while lifting off the brakes.
5. Since the AutoX areas are compact: abrupt braking to steering input will
actually work well to a point before the lenghts of the course get
Tell us how you do...........
Alignment for the road where 95% of you driving is.
