Tune Helper
Pick a discipline and answer a few questions about what the car is doing. You get a prioritized FH6 checklist (sliders and, on road, the parts build). One change at a time, then retest.
Collaborative tune sheets
Share the actual soft-tune numbers (and car / engine / wheels), not just a share code. Anyone with the link can edit.
My sheets New tune sheetRoad / Circuit
Fix understeer and oversteer, then the parts build: grip vs power, tire width, wheels, weight, and aero.
Drift
Refine initiation, angle hold, transitions, and throttle rhythm. RWD drift builds with differential, alignment, and gearing.
Drag
Dial in launch hook, shift traction, and trap speed → tires, gearing, differential, and suspension for straight-line pulls.
Rally
Build a compliant stage tune or fix loose-surface push, landings, and hairpin bog.
