Moderate clay substrate — drainage and prep response depend on race-night humidity.
Michelin Raceway Road America Kart is a kart track in Elkhart Lake, WI. Three things decide your night: density altitude (how much the air feeds the motor — shown live above), seat and lead placement, and tire pressure as the surface comes in.
As temperature, humidity and barometric pressure shift across a race night near Elkhart Lake, the density altitude above moves with them — and your tune should follow. Most weather apps show sea-level-corrected pressure, which gives the wrong DA; racer.wiki uses uncorrected station pressure for the real number. Read the full density altitude guide →
