Guide execution map
This guide should answer the immediate problem, send the player into the right tool, then keep the next read context-specific instead of sending every page to the same generic list.
First action
Start with open tune calculator before changing unrelated setup groups.
Validation loop
Keep the same car, route, assists, device, and weather while testing one change at a time.
Next handoff
Route unresolved questions into the next-read set below: upgrade order tuning guide, engine swap and drivetrain swap guide, tire pressure settings guide, cross-country and offroad tuning guide.
Match compound to the surface
A road tire can be wrong for dirt, and an offroad tire can waste grip on clean asphalt. Surface matters before horsepower.
- Use road-focused tires for predictable braking and cornering.
- Use rally or offroad choices when bumps and dirt decide the route.
- Use drift or drag-focused choices only when the event demands it.
Watch the PI tradeoff
Better tires can consume enough PI to block power, aero, or weight reduction. The best compound is the one that solves the route without ruining the class target.
- Avoid over-tiring low-power cars if they start to bog.
- Spend tire PI early when the car cannot put power down.
- Save a lower-grip version for class-restricted events.
Tune pressure after choosing compound
Tire pressure is the fine adjustment. Compound is the larger decision. Do not try to fix a wrong compound with tiny pressure changes.
- Pick compound first, then pressure.
- Retest heat, grip, and exit behavior on the same route.
- Use pressure guidance when the tire choice is already close.
Deep dive
Tire compound decision paths
Use surface, class, and handling symptoms to decide whether the tire choice needs to change.
Road car slides everywhere
The compound may be too weak for the power, route, or weather.
- Try a higher-grip road compound.
- Check tire pressure after the swap.
- Avoid adding power until exits are stable.
Car bogs after tire upgrade
The tire may have added more grip and PI cost than the engine can use.
- Retest with a lower compound.
- Use gearing if the car falls out of power.
- Compare lap time rather than grip feel alone.
Mixed-surface event feels random
The wrong compound can make dirt, grass, or wet sections unpredictable.
- Use rally or offroad guidance.
- Tune suspension for bumps.
- Keep a dedicated mixed-surface preset.

Turn this guide into one repeatable setup note
A guide page should leave the player with a short test note, not a pile of disconnected slider ideas. These fields keep each FH6 guide useful after the first read.
FieldWhat to capture
Car and classRecord the exact car, PI class, drivetrain, and upgrade direction.
Route or eventName the route section, drift zone, speed trap, or weekly restriction.
Setup changeWrite one changed setting group instead of listing every slider.
ResultKeep, undo, or retest the change with the same car and route.
Next actionOpen the Tune Calculator or a related guide if the issue remains.
Keep the change
The car improves in the target section without creating a new problem elsewhere.
Retest smaller
The direction is useful, but the car now feels nervous, dull, slow, or inconsistent.
Undo and reroute
The change hides the real issue. Move to the linked calculator, settings page, or related guide.
