Rain-Ready in Minutes
Wet Setup Workflow
Using a baseline dry setup, make initial changes based upon suggestions below
Take car out for a few test laps, be sure to get tires into operating window
Identify the problem area
Note where the understeer/oversteer is occurring
Slow corners, fast corners, corner-entry, or mid-corner
Make setup adjustments incrementally
Start with a single adjustment
Note change made
Test the effect
Start with the easiest changes:
Adjusting ride height, ARBs, and aero are often the simplest ways to achieve a significant change in car balance.
Fine-tune with dampers:
Use damper settings to precisely tune the car's behavior during specific phases of the corner.
