13' Porsche 911 GT3 RS Tune List
Tire Pressure
- Front: 22.5 PSI
- Rear: 22.5 PSI
Lower pressure makes tires warmer and stickier, giving you more grip in corners.
Alignment
- Camber Front: -1.8°
- Camber Rear: -1.0°
- Toe Front: 0.1° (Out)
- Toe Rear: 0.0°
- Front Caster Angle: 6.5°
Tilting the front tires slightly out helps the car point into corners instantly. The camber angles keep the tires flat on the road during hard turns.
Antiroll Bars
- Front: 12.00
- Rear: 42.00
A softer front bar helps the front grip during turns, while a stiffer rear bar stops the car from feeling lazy or slow to react.
Springs
- Front Springs: 380.0 LB/IN
- Rear Springs: 650.0 LB/IN
- Ride Height Front: 3.4 IN
- Ride Height Rear: 3.0 IN
Keeping the front springs softer helps the weight shift forward when you brake. Lowering the car keeps it stable at high speeds.
Damping
- Rebound Stiffness Front: 8.5
- Rebound Stiffness Rear: 11.5
- Bump Stiffness Front: 4.8
- Bump Stiffness Rear: 6.5
This controls how the car handles bumps. It stops the car from bouncing up and down too much, keeping the ride smooth.
Aero
- Downforce Front: 134 LB
- Downforce Rear: 580 LB
Wind pushes down on the car. Max front downforce helps you turn at high speeds, while high rear downforce stops the back end from sliding out.
Brake
- Braking Force Balance: 48%
- Braking Force Pressure: 110%
Pushing the brake balance slightly backward helps the car turn while slowing down. 110% pressure lets you stop quickly without locking up the tires.
Differential
- Rear Acceleration: 52%
- Rear Deceleration: 24%
52% acceleration helps you push out of corners without spinning the tires. 24% deceleration helps the car turn smoothly when you let go of the gas pedal.
