73’ 911 Carrera RS Tune List
Tire Pressure
- Front: 28.0 PSI
- Rear: 27.0 PSI
This gives the tires maximum grip so the car stays stuck to the road and does not slide around.
Alignment
- Camber (Front): -1.8°
- Camber (Rear): -1.2°
- Toe (Front): 0.1° (Out)
- Toe (Rear): 0.0°
- Front Caster: 6.2°
This tilts the wheels slightly to keep the tires flat against the road when you turn, keeping the heavy back end of the car stable.
Antiroll Bars
- Front: 18.00
- Rear: 32.00
Explanation: Keeping the front soft makes steering feel smooth, while a stiffer rear helps this rear-engine car rotate around corners.
Springs
- Spring Rate (Front): 180.0 LB/IN
- Spring Rate (Rear): 340.0 LB/IN
- Ride Height (Front): 5.4 IN
- Ride Height (Rear): 6.6 IN
This lowers the car closer to the ground for better balance, and keeps the rear stiffer to support the heavy engine in the back.
Damping
- Rebound Stiffness (Front): 9.5
- Rebound Stiffness (Rear): 11.5
- Bump Stiffness (Front): 2.8
- Bump Stiffness (Rear): 3.4
This stops the car from bouncing up and down when you drive over road bumps.
Differential
- Rear Acceleration: 60%
- Rear Deceleration: 15%
This helps you speed out of corners without spinning your tires, but lets the car turn easily when you let go of the gas.
