Fast Forward to 1994
With the advent of newer tires that had a lot
more bite, cars were being offset with the right side tires being a lot
further out from the frame than the left side tires.
Fast Track Racing introduced the first Offset Zero Scrubb Axle
This axle was patterned after the original FX Axle but
it was extended on the right side to OFFSET the car. In addition many new
ideas were incorporated
Both front spindles were moved inside the front wheels
so that each wheel would pivot on the center of the tire where it
touched the ground instead of moving in an arc. This made it easier
to steer and eliminated Bump Steer.
(The RF wheel used a 4" rim
on the inside and a 2" rim on the outside).
The right front spindle bracket had a new Fast
Track Camber Adjust Block
The spindle arms were redesigned and curved to clear the wheels.
From the 1996 Fast Track catalog (shown) you had your
choice of axles --
FX & FEX axles
F/T Standard Swept Axle with and without Camber
A Straight Front Axle
Straight and Swept Axles for 10 degree spindles (for
and the New Fast Track Offset axles in 2 different lengths
In 1986 ----
Fast Track Racing introduced the first production
It was sold with or without Torsion Bars. ( Most cars
ran torsion bars at this time.)
The axle was still the Standard Swept Axle - no offset yet.
These axles used the Clicker Shocks and springs made just for
The "Quarter Midget Shocks" had not been designed or
New Offset Front Axle with a Low
Mount Coil bracket
In 1996 Fast Track offered an offset front
axle for a coil car with the shock and coil mounted on the back side of
the axle and down low. This axle still used the clicker shocks and springs
designed for them but newer shocks designed just for Quarter Midgets were
coming on the market.
|The 1996 Fast Track catalog also showed a New
Lightweight Aluminum shock using larger diameter coil springs.
These springs would soon become the springs of choice and the new
"Quarter Midget Shocks" would take over.
NEW Nervo/Coggin Quarter Midget --
(John Nervo had been
driving Fast Track cars and was featured
on the cover of the Fast Track Racing catalog for 1991)
When NC Chassis brought out their
first car it used the same Fast Track Frame design and the same Offset Front axle but instead of
using torsion bars, Coil Over Shocks were mounted using the same tabs on
top of the axle as were originally used for the Torsion bars.
This proved to be a winning combination and soon all cars were switching
from Torsion bars to Coil Over's.
Other car manufacturers soon came out with
their own offset axles with the Coils mounted on top of the axle and with
the same Fast Track Camber Adjust blocks. All these axles used the new
curved arm spindles designed for Zero Scrubb. As time went on all
manufacturers moved the shock mounts from the top of the axle to the
backside of the axle.
Over the years the Offset Axles
have varied in length from 29" - 32" (measured spindle to
spindle). In the last few years they have settled at 30" for asphalt.
On some axles like Fiser and Stanley, the "U" bracket and
Spindle tube have been reversed with the Spindle tube welded to the end of
the axle and the "U" bracket being part of the spindle but they
still use the same basic Swept Axle design.
The axles have also been redesigned to use 3 bends (instead of 4), 2 bends and
even down to 1 bend but the whole idea of giving the driver more legroom
SUPER FRONT AXLES
Along the way, NC redesigned their front
axle to use fully adjustable "U" brackets with little
aluminum Camber adjust blocks. (It still uses the same curved arm spindles)
That was a good idea and so - the Super Front Axle from Boomerang
(We have made axles for our cars and many other cars using the NC adjustable "U" brackets and Camber blocks)
So - it all began with the FX
Front Swept axle

Have a good day and keep
