Posted November 11, 2025Professional Physics-Based Tuning
This interactive tool helps you diagnose setup problems and apply real physics-based adjustments.
Unlike generic guides, each recommendation explains the physics behind the change—so you understand
not just WHAT to adjust, but WHY it works.
Front Tires Locking in Braking
Car brakes straight but front wheels lock before rear. Loss of directional control.
Understeering into Turn (Braking)
Can't turn the car while braking. Pushing straight into the corner despite brake release.
Oversteering into Turn (Braking)
Rear sliding out while braking and turning. Loss of rear traction in braking zones.
Car Pitches Too Much (Dives Excessively)
Front end dips too aggressively. Nose hits the track surface or porpoising into corners.
Brake Balance Finding Issue
Either front-heavy (locking) or rear-heavy (instability). Struggling to find the sweet spot.
Inconsistent Braking Performance
Different braking points lap to lap. Brake fade affecting consistency or setup temperature sensitive.
Understeering at Turn In
Can't turn the wheel in far enough. Need to slow down more than expected to change direction.
Oversteering at Turn In
Front grip is there but rear slides out immediately after initial steering input. Snap oversteer.
Sluggish Turn-In Response
Steering inputs delayed. Car takes a while to rotate. Needs multiple steering corrections.
Too Twitchy/Responsive Turn In
Minimal steering input creates excessive rotation. Hard to modulate. Over-correcting constantly.
Can't Hit Apex Consistently
Line feels wrong. Either turning in too early or too late. Inconsistent apex placement.
Inside Wheel Lifting/Locking at Turn In
Inside tire loses grip or locks. Car feels unstable entering corners. Tire pressure too high or suspension too stiff.
Mid-Corner Understeer
Front tires lose grip at apex. Can't maintain the line. Need to open steering wheel mid-corner.
Mid-Corner Oversteer
Rear slides out mid-corner. Car wants to spin. Especially bad on throttle.
Tire Chattering/Vibration at Apex
Front tires feel loose. Vibration through steering wheel. Tires oscillating near grip limit.
Car Bounces During Turn
Suspension pogo-ing. Especially on curbs or bumpy track sections. Loss of grip momentarily.
Balance Changes Mid-Corner
Balanced at turn-in but unstable at apex. Or balanced at entry but unpredictable at apex.
Excessive Tire Scrub/Sidewall Flex
Tires feel squishy mid-corner. Pressure too low. Temperature build-up excessive.
Loss of Traction on Throttle (Exit)
Rear wheels spin up easily. Can't apply full throttle without losing grip. Wheelspin issues.
Oversteer on Throttle (Exit Slide)
Rear breaks loose when accelerating. Car slides sideways exiting the corner. Hard to control.
Understeer on Exit
Can't turn while on throttle. Car pushes wide despite steering input. Need to lift throttle to turn.
Dead Feeling Exit (No Feedback)
Exit feels numb. Hard to feel what the car is doing. Difficult to meter throttle application accurately.
Snap Oversteer (Sudden Snap)
Exits fine until suddenly rear breaks loose unexpectedly. Hard transition from stable to sliding.
Loss of Grip Exiting Over Curbs
Curbs upset balance. Can't use aggressive lines. Lose traction when transitioning from curb to track.
Tires Too Cold (First Lap)
No grip on opening lap. Tires need heating up. Slippery initially then grips better as lap progresses.
Tires Overheating
Temperatures too high. Grip drops mid-stint. Tire fade after 5-10 laps. Loss of performance.
Tire Pressure Too High
Steering feels numb. Tire sidewalls too stiff. Harsh ride. Bumpy track sections cause loss of grip.
Inner edge wearing too fast. High camber angles or too much steering input. Tire getting shredded.
Excessive Outer Edge Wear
Outer edge wearing heavily. Not enough negative camber or too much load on outside tires.
Center Line Wearing Fast
Middle of tire flat-spotting. Too much straight-line performance demanded. Tire pressure too high.
Blistering/Chunks Missing
Tire surface tearing. Over-temperature or excessive slip. Degradation too fast.
Tire Heat Management Guide
Learn how to manage tire temperatures for optimal performance. Find the sweet spot between grip and tire life. Real-world strategies for heat management.
Poor Low-Speed Performance
Slow through tight technical corners but OK at high speed. Need more mechanical grip in slow-speed sections.
Poor High-Speed Stability
Fast sweepers feel unstable. Aero balance wrong or suspension too soft. Twitchy at speed.
Poor Bump Handling
Bumpy sections lose grip. Suspension too stiff or too soft. Porpoising on ripples.
Elevation Changes Causing Issues
Cresting hills causes loss of grip. Downhill sections different balance than flat sections.
Can't Use Aggressive Curb Lines
Hitting curbs destabilizes the car. Suspension too stiff or ride height wrong. Should be hitting them more.
Numb/Dead Mechanical Feel
Car feels disconnected. Hard to sense what's happening. Feedback through steering wheel minimal.
Inconsistent Setup Performance
Setup changes from session to session. Temperature or fuel load affecting behavior too much.
Poor Wet Weather Performance
Transitions to wet are too aggressive. Car is undriveable in rain or damp conditions.
