The following template was designed to assist you in breaking down the corner into three main areas. First, establish what handling characteristic your car possesses, then, using the template, determine in what area of the corner you are experiencing the problem. Follow the recommended adjustments in order to optimize your vehicle’s cornering potential.
0° thru 60° Corner Entry
Problem: Loose at turn entry
Increase compression on front or right front
Decrease rebound in left rear
Problem: Tight at turn entry
Decrease compression on front or right front
Increase rebound in left rear
60° thru 120° Mid Corner
At most tracks this part of the corner is where the car has taken a set. Your braking is already done, your steering angle is constant and you are getting ready to pick up the throttle. Typically, your car’s handling characteristics are influenced by vehicle geometry and roll centers at this part of the track and less likely affected by shock valving.
120° thru 180° Corner Exit
Problem: Loose at turn exit
Decrease rebound in right front
Decrease compression in left rear
Problem: Tight at turn exit
Increase rebound on right front
Increase compression on rear or right rear only
Always start tuning by concentrating on the problem that happens first in the turn. For example, if you are loose exiting the turn, it is possible that it is happening because you are tight entering the turn. The extra steering input from trying to “drive through the push” could cause the car to seem loose at mid-corner and at exit. Once the “push” entering is fixed, the loose condition exiting the corner could go away.
