Track Tuning
(GENERAL):
Compression Adjuster:
This adjuster is typically used when looking to improve the car over bumps. If your vehicle is hitting a
certain bump that is causing the vehicle to “unload” the tire, simply soften the compression adjustment.
This will allow the shock to absorb the bump, there keeping the vehicle more stable and making the car
more controllable.
You can also use this adjuster to help in controlling the “platform” of the car, or the body roll. Example‐
If you are entering a corner and under braking the front of the car is diving to quickly or the weight
being transferred from the back to the front is too much, simply close the compression adjuster on the
front to slow that weight transfer down.
Rebound Adjuster:
The rebound adjuster is a great tool for tuning body roll. This is a much more driver sensitive adjustment
than the compression. If you want to slow the pitch of your car from the back to the front, simply close
the rebound off, this will slow the weight transfer.
When you are accelerating off a corner, getting weight transfer to the rear tires is very important for
grip or “forward bite” as its reffered to sometime. By softening the front rebound, this will allow for
quicker weight transfer to the rear tires, resulting is better rear grip. Be careful though, by allowing to
much weight transfer to the rear, you may cause a loss of front grip, resulting in an “under steer” or
“tight” condition.
Important!!
You can over adjust. Always have a baseline to go back to!!!
Track Tuning
(DRAG RACING):
Normal adjustment steps for Drag Racing:
Compression:
Adjust 5 clicks at a time.
Rebound:
Adjust 2 sweeps at time.
To Increase Bite:
Soften compression or stiffen rebound. Example: hot and greasy track / bald spots on starting line.
To Decrease Bite:
Stiffen compression or soften rebound. Example: Track conditions are at their best / starting line is
covered with good rubber.
When using a pneumatic (air) bleed off eyelet: As each chassis and track is different, we recommend
consulting a Penske technician for help with the setting of timers and other air bleed‐off mechanisms.
