1] Position
first, then speed. Positioning
the car perfectly is more important than trying to attain
the highest potential speed. For example, you will drop more
time by correctly positioning the car nearer to slalom cones
than you will by adding 1 or 2 MPH in speed. Same with sweepers
(tight line). Same with 90-degree turns (use all of the track).
Also, position is a prerequisite for speed. If you are not
in the correct place, you will not be able go faster. Or
at least not for very long!
2] Turn
earlier...and less. To go faster, the arc you are running
must be bigger. A bigger arc requires less steering. To make
a bigger arc that is centered in the same place, the arc
must start sooner (turn earlier).
3] Brake
earlier...and less. Waiting until the last possible second
approaching a turn and then dropping anchor at precisely
the correct place so that the desired entry speed is reached
exactly as you come to the turn-in point is quite difficult
to execute consistently. Especially when you consider that
you get no practice runs on the course, and the surface changes
on every run, and you aren't likely to be in exactly the
same position with the same approach speed on every run,
etc. Better to start braking a little earlier to give some
margin of error. And by braking less you can either add or
subtract braking effort as you close in on the turn-in point.
This will make you consistent and smooth.
4] Lift
early instead of braking later. Continuing with the philosophy
of #3, when you need to reduce speed only a moderate amount,
try an early lift of the throttle instead of a later push
of the brake. This is less upsetting to the car, is easier
to do and thus more consistent, and allows for more precise
placement entering the maneuver (remember #1 above).
5] Easier
to add speed in a turn than to get rid of it. If you are
under the limit, a slight push of the right foot will get
you more speed with no additional side effects. On the other
hand, if you are too fast and the tires have begun slipping,
you can only reduce throttle and wait until the tires turn
enough of that excess energy into smoke and heat. Don't use
your tires as brakes!
6] Use
your right foot to modulate car position in constant radius
turns, not the steering wheel. In a steady state turn, once
you have established the correct steering input to maintain
that arc, lifting the throttle slightly will let the car
tuck in closer to the inside cones. Conversely, slightly
increasing the throttle will push the car out a bit farther
to avoid inside cones. It is much easier to make small corrections
in position with slight variations in the tires' slip angle
(that's what you are doing with the throttle) than with the
steering wheel.
7] Unwind
the wheel, then add power. If the car is using all of the
tire's tractive capacity to corner, there is none left for
additional acceleration. At corner exit, as you unwind the
wheel, you make some available. If you do not unwind the
wheel, the tire will start to slide and the car will push
out (see #6 above).
8] Attack
the back. For slaloms (also applicable to most offsets),
getting close to the cones is critical for quick times (see
#1). To get close, we must move the car less, which means
bigger arcs. Bigger arcs come from less steering and require
earlier turning (see #2). Now for the fun part... When you
go by a slalom cone and start turning the steering wheel
back the other way, when does the car start to actually change
direction? Answer: When the wheel crosses the center point
(Not when you first start turning back!) How long does that
take? If you are smooth, it takes .25 - .5 seconds. Now,
how long is a typical person's reaction time? Answer: about
.5 seconds. Finally, how long does it take to go between
slalom cones? Answer: Typically on the order of 1 second.
Given all of that, your brain must make the decision to begin
turning the steering wheel back the other way just *before*
you go by the previous cone!!
Since this is a mental issue, a good visualization technique to
get used to this is to think about trying to run over the
back side of each slalom cone with the inside rear tire of
the car. To hit it with the rear tire (and not the front),
the car must be arcing well before the cone and the arc must
be shallow. Attack the back!
9] Hands
follow the eyes, car follows the hands. 'Nuf said.
10] Scan
ahead, don't stare. Keep the eyes moving. Looking ahead does
not mean staring ahead. Your eyes must be constantly moving
forward and back, and sometimes left and right. Glance forward,
glance back. Your brain can only operate on the information
you give it.
Bonus
Tip: Don't forget the stuff in between
the marked maneuvers! Too often we think of a course as
series of discrete maneuvers. There is typically more to
be gained or lost in the areas that are in between. Pay
special attention to the places where there are no cones. |
