patented Windows software program is the
the answer to winning performance on the race track!
have discovered that the roll center location is the most important
aspect of the front a stock car. Use this software to easily find
your front roll center in both static and dynamic location. This
roll center software program also features the tools that will allow
you to quickly re-design your own chassis for optimum racing
performance. This program is the Absolute Easiest To Use Ever.
Convenient data entry next to a
full screen picture diagram of your chassis. Re-design your
own race car fast and easy. This Windows program provides easy
reading help files that cover an extensive listing of topics on
Geometry Software allows you to change your arm angles and arm
lengths. Enter dive and roll to see where the Roll Center moves to
in the turns. This program also recalculates your chassis's
dimensions for you and then shows how far each point moved after
re-design of the chassis.
FREQUENTLY ASKED QUESTIONS ABOUT
FRONT ROLL CENTERS:
Q. WHAT IS A FRONT ROLL CENTER?
The front roll center
is a geometric point in a double-A arm suspension that is located by
using the angles of the upper and lower control arms. Some
individuals have drawn out the suspensions on their cars to find the
roll center location, but it is much faster and a whole lot easier
to use a computer program. And, we need to know where the
front roll center moves to while the car is in the turns. We
know the roll center moves after dive and roll. The roll center
location is the most important factor in determining how the front
end will work as the car goes through the turns.
Q. WHY DO I NEED TO KNOW WHERE MY FRONT
ROLL CENTER IS LOCATED?
The front roll center
location determines how the weight transfers in the front end of the
car and how much the cambers will change for the left front and
right front wheels. Adverse weight transfer or camber change
characteristics can be a major problem causing the car to push in
the middle of the turns. Each race car requires a certain roll
center location based on the type of racing (dirt or asphalt) and
what kind of race track (banking angle and surface conditions) in
order for the tires to perform the best. The front end will
never work to itís maximum capacity unless the roll center is
located in the right place.
Q. WHAT WILL ROLL
CENTER SOFTWARE DO FOR ME?
A good roll center
software program will first of all be very Easy to use. Letís face
it, weíre racers, not rocket scientists. A good program should
tell us where the roll center is located at ride height and also
where it moves to in the middle of the turns. We need the Roll
Center to be at itís best location for our intended use when the car
is in the turns. A good program should tell us camber changes
also. And, to make changing the Roll Center location easy, it
should tell us the original control arm angles and lengths, then
allow us to change the angles and lengths easily. With the Chassis
R&D Geometry software, all you have to do is type in the new arm
angles, and/or the new arm lengths. The program will show the new
Roll Center locations and tell you how far the pickup points have
moved from the original locations.
Q. HOW DO I USE THE INFORMATION?
Once you have
determined the location of the Roll Center and the camber change
information for your car, you need to determine if you will need to
change any arm angles or arm lengths to make the roll center
location better for your use. The software allows you to do
this quickly and easily.
Q. DOESN'T MY CHASSIS BUILDER KNOW WHERE
MY ROLL CENTER IS LOCATED?
He may know where
he designed it to be, but are your arm lengths the same as he
designed for your car? Also, until recently, none of us (including
all of the car builders) understood the importance of Roll Center
location as it applies to the dynamics of the car. Many well known
race car builders across the country are now rethinking the designs
of their cars related to roll center design. Remember, it is up to
YOU to make sure your race car has what it needs in order to
out-perform your competition.
