Determining Offset
(TR-212)
After having completed the alignment as described above many racers like to have their
right rear wheel follow the right front wheel. This is called Offset. To determine Offset
we have found this very useful.
1) Leaving the TR-37 Laser Gun in place and the toe dialed in. Take the TR-36 Laser
Gun and put on the Front Right Wheel Clamp or Hub Adapter and set the toe dial to
zero.
2) Straighten out the right front wheel by turning the steering wheel until the wheel is in
the straight ahead position.
3) Place a Frame Centering Flag at the center of the vehicle on the side that is being
Offset.
4) Level and turn on the Laser Guns so that they are pointing at each other.
5) Record the Offset at the Frame Centering Flag and make changes as necessary.
Note:
If you are using Hub Adapters, you will need to put a spacer of the same
thickness on the Hub Adapter for every wheel spacer you put on.
5a) For Contact Patch Offset, take a straight edge and place it at the Laser Beam and
measure into the contact patch of the tire and record your Offset.
Note:
The TR-36 & 37 Gauges for stockcars have had the scales
changed to reflect having the gauges mounted to the car in
reverse fashion. If you place the gauges in a normal
configuration I.E. guns on the front pointing back, toe
readings will be
OUT is IN and IN is OUT.
