Best Tire and Suspension Settings in Gran Turismo 7 are the starting point for turning a decent lap into a competitive one. Tires and suspension work together, tires provide the grip window, suspension shapes weight transfer, and the combination controls how predictable the car feels under braking, turn in, mid corner, and on exit. Tuning these systems correctly reduces tire scrub, prevents understeer or snap oversteer, and gives you a usable limit you can exploit every lap.
Start With The Correct Tire Choice
Tire compound is the single biggest factor. Choose a compound that matches track temperature and race length. Soft tires offer peak grip but heat and wear quickly. Medium is a balanced choice for most events. Hard or sports tires are for long stints and heavy cars. Always test qualifying pace and stint degradation before committing.
Tire Pressure, The Foundation
Tire pressure controls contact patch behavior. Too high reduces contact and grip, too low increases rolling resistance and overheating. Use pressures to tune balance:
- Lower cold pressure increases initial grip but risks overheating over a stint.
- Higher pressure improves turn in precision but reduces mid-corner bite.
Practical baseline: start with manufacturer or default pressures. Then adjust by 0.1 – 0.3 psi increments. For front-heavy cars, slightly lower front pressures help mitigate understeer. For twitchy rear end cars, lower rear pressures to increase rear stability. Finding the Best Tire and Suspension Settings in Gran Turismo 7 often begins by balancing tire pressures before moving to suspension tweaks.
Camber, Maximize Lateral Grip
Camber determines how flat the tire sits during cornering. Negative camber increases cornering grip but reduces straight line braking traction if overdone.
Baseline camber approach:
- Street cars: -1.0° to -2.0° front and rear.
- Racing cars: -2.0° to -3.5° front, -1.5° to -3.0° rear depending on suspension setup.
Tune by measuring tire temperature across the tread after a short run. Hotter inside edge = too much negative camber; hotter outside edge = not enough camber.
Toe Settings For Stability And Turn In
Toe affects responsiveness and straight-line stability. Toe-in (front) improves stability but slows turn-in. Toe out (front) sharpens initial turn-in but can make the car nervous on straights.
Typical recommendations:
- Front toe: slight toe-out (0.00 to – 0.05) for sharper turn-in on race cars.
- Rear toe: small toe-in (0.02 to 0.10) for stability under throttle and braking.
Fine-tune toe by observing corner entry behavior and high-speed wobble. If the car wanders on full throttle, increase rear toe-in slightly.
Ride Height And Center Of Gravity
Lower ride height reduces center of gravity and aerodynamic drag but can make the car skittish over curbs. Raise it for bumpy tracks or heavy ride movement. GT7’s ride height also changes corner balance.
Quick rules:
- Lower evenly front and rear for better aero and lower roll moment.
- If the car understeers, lower the rear relative to the front to shift load rearward during cornering.
- For oversteer, lower the front slightly or raise the rear to increase front bite.
Spring Rates, Control Weight Transfer
Springs dictate how quickly weight shifts. Stiffer springs reduce body roll and improve responsiveness at the cost of traction on uneven surfaces. Softer springs increase mechanical grip but can make the car feel wallowy.
Practical tuning:
- Stiffen front springs to reduce understeer on turn-in.
- Soften rear springs to improve traction on exit if the rear slides under power.
- Use small incremental changes. Huge jumps cause unpredictable behavior.
Anti Roll Bars For Roll Control
Anti-roll bars limit body roll without affecting ride height. A stiffer front bar increases initial turn-in but may provoke understeer mid-corner. A stiffer rear bar tightens the rear and can reduce understeer but increases oversteer risk.
Rule of thumb:
- If you understeer, stiffen the rear bar or soften the front bar.
- If you oversteer, stiffen the front bar or soften the rear bar.
Damping, Rebound And Compression Tuning
Damping controls how the car absorbs and recovers from load changes. Compression damping affects how the suspension compresses under load. Rebound damping controls how it extends back.
Start conservative:
- Slightly softer compression for bumpy tracks to maintain contact.
- Moderate rebound to avoid oscillation after curbs or kerbs.
Tune by observing how the car settles after direction changes. If it bounces back slowly and feels sluggish, reduce rebound. If it oscillates, increase rebound damping.
Track Specific Adjustments
No single setup fits all tracks. Adapt for:
- Short Twisty Tracks – softer springs, more front camber, slight front toe-out for quick direction changes.
- High Speed Circuits – stiffer springs, more negative camber, higher pressures for straight-line stability.
- Bumpy Street Tracks – higher ride height, softer damping, slightly lower tire pressures to keep contact patch consistent.
Practical Tuning Workflow (Step By Step)
- Start with the recommended default setup for your car model.
- Select the correct tire compound for the session.
- Set baseline tire pressures and run 3 – 5 laps to heat tires.
- Check tire temps across the tread and adjust camber accordingly.
- Tweak toe to correct straight-line stability or turn in laziness.
- Adjust springs and ARBs to fix understeer/oversteer balance.
- Fine-tune damping to control body motion and curb behavior.
- Repeat test laps and log lap times, small changes are cumulative.
Tips And Common Pitfalls
Monitor lap to lap consistency, not just peak lap time. A slightly slower but repeatable lap is more valuable in races. Avoid extreme settings, they may produce a single quick lap but fail under fuel load or tire wear. Keep notes of settings and track conditions. Use ghost laps and replays to compare lines and corner exit speeds after each setup change.
Finding the Best Tire and Suspension Settings in Gran Turismo 7 is an iterative process that rewards patience and methodical testing. Start with sensible baselines: correct tire compound, moderate pressures, conservative camber, and neutral toe. Then tune springs, anti-roll bars, and damping to refine behavior for the specific track and driving style. Focus on consistency and predictability. When the car feels stable and responsive lap after lap, you’ve found a setup you can rely on to push harder and improve times.
