Tuning your car with shocks (Dirt)
In order to trouble shoot shocks, we first have to look at the track The corners are where we are going to get our speed. So letís look at the different stages of a corner where shocks do the most work, keep in mind that these are base figures and donít take into account the style of track, kind of car, set up, or driving style.

Stage one: Early Entry
This is when you are off the gas and start applying the brakes; also you are starting to turn into the corner. How fast the transition from straight-aways to apex of corner will determine the effects of the LR shock, wide turns will require less rebound in the LR

Shocks most affected:
RF-Compression
RR-Rebound
LR-Rebound
LF-Compression

How to tighten car:
RF-Compression (Dec)
RR-Rebound (Dec)
LR-Rebound (Inc)
LF-Compression (Inc)

How to loosen car up:
RF- Compression(Inc)
RR- Rebound (Inc)
LR- Rebound (Dec)
LF-Compression (Dec)

Stage two: Primary Entry
This is when you are decreasing the pressure on the brakes and increase the steering input into the corner.

Shocks most affected:
LF-Rebound
RR-Compression
RF-Compression
LF-Compression

How to tighten car:
LF-Rebound (Dec)
RR-Compression (Inc)
RF-Compression (Dec)
LF-Compression (Inc)

How to loosen car up: LF-Rebound (Inc)
RR-Compression (Dec)
RF-Compression (Inc)
LF-Compression (Dec)

Stage Three: Middle of Corner
This is the stage where the car takes a set, you start applying throttle and continue with steering input.
Shocks most affected:
RF-Compression
RR-Compression
LF-Rebound
LR-Compression
RF-Rebound

How to tighten car:
RF-Compression (Inc)
RR-Compression (Dec)
LF-Rebound (Inc)
LR-Rebound (Dec)
RF-Rebound (Dec)

How to loosen car up:
RF-Compression (Dec)
RR-Compression (Inc)
LF-Rebound (Dec) LR-Rebound (Inc)
RF-Rebound (Inc)

Stage four: Middle of corner to exit of corner
This is the stage where steady power is being applied and steering has been reduced. In a lot of cases increasing the compression on the LR shock has tightened the car. Example: dry slick tracks.

Shocks most affected:
RF-Rebound
LR-Compression
LF-Rebound
RR-Compression

How to tighten car:
RF-Rebound (Dec)
LR-Compression (Dec)
LF-Rebound (Inc)
RR-Compression (Dec)

How to loosen car up:
RF-Rebound (Inc)
LR-Compression (Inc)
LF-Rebound (Dec)
RR-Compression (Inc)
