04’ Porsche 911 GT3 Tune List
Tire Pressure
- Front: 22.0 PSI
- Rear: 22.0 PSI
Lower pressure makes the tires stickier so the car has more grip and does not slide around turns.
Alignment
- Camber Front: -1.5°
- Camber Rear: -0.8°
- Toe Front: 0.0°
- Toe Rear: 0.0°
- Front Caster Angle: 6.2°
This tilts the wheels slightly so that when you turn, the tires lay completely flat on the road for maximum grip.
Antiroll Bars
- Front: 15.00
- Rear: 40.00
This stops the car from leaning too much. A softer front helps the car steer easily, while a stiffer rear keeps the back end following smoothly.
Springs
- Front Springs: 350.0 LB/IN
- Rear Springs: 650.0 LB/IN
- Ride Height Front: 4.4 IN
- Ride Height Rear: 4.4 IN
This controls how the car bounces. Since the engine is in the back of this Porsche, the rear needs stiffer springs to support the weight, and keeping the car low to the ground helps it go faster.
Damping
- Rebound Stiffness Front: 8.0
- Rebound Stiffness Rear: 11.0
- Bump Stiffness Front: 4.5
- Bump Stiffness Rear: 6.0
This controls how fast the springs bounce back. It helps the tires stay in contact with the road when driving over bumps.
Aero
- Rear Wing: 680 LB
The wing pushes air down on the back of the car, keeping the rear tires glued to the road so you do not spin out.
Brakes
- Braking Force Balance: 50%
- Braking Force Pressure: 100%
This shares the stopping power equally between the front and back wheels so you can slow down quickly without sliding.
Differential
- Rear Acceleration: 45%
- Rear Deceleration: 20%
This controls how power goes to the rear wheels. It helps you speed out of corners without the rear tires spinning out of control.
