#2: Event Preparation
Adam Lewis
Ladies and Gentlemen, we are under way! The South Bend Region kicked
this years Solo season off with a bang once again! 106 entries with
plenty of new faces, made our
first event of the season spectacular. It was also my first event as
tech chief. I gotta tell ya, I learned a whole lot more than I expected
to that day, and I wish to pass that information along to you. They say
hindsight is 20/20, but in Solo we need to be looking ahead, which is
what this article is about, looking, and planning ahead. Things you can
do before, during, and after an event.
Things you can do before coming to an
event:
- Check all of your engine’s fluids. We all know the importance of
having proper fluid levels. Make sure they’re where they should be.
- Clean the car up: Make it look presentable. Solo II events are
not only a competition, but a car show of sorts. Clean her up and
show her off a little because, chances are your car will be
photographed, and possibly posted on the web. Everybody loves a
shiny car. Remove anything and everything that doesn’t apply to
autocross, or the journey to and from.
- Do a quick inventory of the things you plan to bring with you. I
can’t tell you how many times I’ve found my self at an event and
have forgotten something. This is experience talking here. Get stuff
together the day prior.
- Do a quick inspection of the car’s ball joints and tie rod ends
if possible. Solo II can put a lot of stress on these parts, and you
really do NOT want them to break during competition.
Example: This is a 1998 Eclipse GS-T that belongs to a friend of
mine.
Here is the same car as it sits right now
The passenger side ball joint broke while he was doing less than 10
mph. He was very fortunate that his speed was low, and he was only 150
yards from home, because when it broke he lost all steering
capabilities. The lower control arm fell to the road, causing the
suspension to drop, and bringing the wheel into the fender causing a lot
of damage. The CV axle was also pulled right out of the transmission.
There’s more damage than that, but you get the idea. A simple inspection
of the ball joint would have revealed a serious problem.
How to inspect your ball joints and
tie rod ends:
The best way I’ve found to do this is to get both front wheels up in the
air. Jack the car up and place it securely on jack stands, and then
place wheel chocks behind the rear wheels. With the car up and the
steering locked, grab the top and bottom of the front tires and give
them a firm jiggle. There should be no movement or “slop.” Grab the
tires by the sides and do the same. From side to side, there may be a
little movement, so watch the steering wheel as you do this if possible.
If the steering wheel is not moving, but the front wheel is, or you hear
a slight clunking sound, there may be a problem. A visual inspection of
the ball joints and tie rod ends is also in order. Many vehicles have
“serviceable” tie rods and ball joints; i.e., they need lubed. If you
are unsure on how to properly lube these parts, or how to visually
inspect them, please seek assistance. Nothing I can say here will
remotely compare to a visual demonstration by a mechanic or competent
“Do It Yourselfer”.
Once you arrive at an event:
After you arrive, and find yourself a cozy little spot in the paddock,
you have one of two options. Get registered, or go through tech. If you
arrive before registration opens, then you have a little time to spare,
but not as much as you might think. If you arrive after registration is
open, go see them first. The sooner people get through registration the
better. It just helps get the day going sooner for everybody. I will
have tech inspection open before registration, but before you see me,
there are some things to do. If you are going to change tires, now is
the time. Make sure you torque the lug nuts after your tire change.
I cannot stress this enough.
Remove ALL loose objects from the vehicle. Floormats, cups, child
seats……anything that can move around needs to come out. An innocent
enough garage door opener can quickly turn into a U.F.O. (Unfriendly
Flying Object) in autocross conditions. If you have an after-market
stereo system with a sub enclosure, it needs to be removed also if the
box and amplifier are not securely fastened. If you need to remove this
item, I also ask that you remove the fuse for the main power, or “hot”
wire for the amp. If your system is not equipped with a fusible link,
then I require several layers of electrical tape be wrapped around the
exposed part of the”hot” wires. If the car has hub caps, they gotta go
also. We don’t want one coming off and injuring a course worker. After
everything is removed, place it in a part of your paddock area that is
out of the way so as not to be tripped or run over. Now is a good time
to apply your numbers and class lettering so we know what to write on
your tech sticker.
Going through Tech:
Here is a basic rundown of what to expect from a tech inspection.
- We are going to check the tires. We’re going to visually inspect
them for excessive wear or “cording”. We’re going to give each one a
jolly good shaking to make sure there is no slop in the ball joints,
and to help ensure they are on tight. We’re going to inspect the lug
nuts also, and ask you if you torqued them, if they have been
changed.
- We’re going to check the interior of the vehicle. Anything that
can come loose should be out of there.
- We’re going to check the brake pedal to make sure it is firm and
working.
- We’re going to check the battery to ensure it is fastened
securely. Bungee cords and zip ties are not the answer here folks.
- We’re going to check the throttle return, where applicable. The
“Fly By Wire” cars get to slide on this one.
- We’re going to do a visual safety inspection of the overall
vehicle. Vehicles with random body parts falling off, dangerous
interior conditions, or engines spewing their life blood all over
tech will be disqualified from competition, no exceptions.
- Finally, we’ll be checking your helmet. A SNELL 1995 or newer is
the rule. If I don’t see that sticker in your helmet, you may not
use it, and will have to use a loaner helmet.
OK, you made it through registration, and tech. You’ve walked the
course (several times I hope) and have attended the driver’s meeting.
Now the real fun part. You make your first run!! Did you change tires
this morning? After your first run you gotta re-torque those lug nuts. I
know it sounds crazy, but those puppies have a way of working themselves
off. This is a huge safety concern on
so many levels and I CANNOT stress it enough. Even after the
event is over, and you have your street tires back on, it’s still a good
idea to stop shortly into your return trip home and check the lug nuts.
Well, I think I’ve covered all the bases for this particular article.
Once again, if you feel I am in error, omitted something important, or
wish to share your mega millions lotto winning with me, my
e-mail is always available to
you. I thank you for reading, and leave you with a suggested quote by
the late Carroll Smith.
