08’ Subaru Impreza Tune List
Tire Pressure
- Front: 28.0 PSI
- Rear: 26.0 PSI
Alignment
- Camber Front: -1.5°
- Camber Rear: -1.0°
- Toe Front: 0.1°
- Toe Rear: 0.0°
- Front Caster Angle: 6.0°
Leaning the wheels slightly inward (camber) gives the tires more grip when turning. A tiny outward tilt in the front (toe) helps the car steer into corners quicker.
Springs
- Front Springs: 280.0 LB/IN
- Rear Springs: 379.4 LB/IN
- Ride Height Front: 8.0 IN
- Ride Height Rear: 8.2 IN
Softer springs stop the car from bouncing wildly on rough ground. Keeping the ride height high prevents the bottom of the car from hitting the dirt.
Damping
- Rebound Stiffness Front: 7.5
- Rebound Stiffness Rear: 6.0
- Bump Stiffness Front: 2.2
- Bump Stiffness Rear: 1.6
Dampers control how fast the springs stretch and compress. Keeping them relatively soft helps the tires stay in contact with the ground instead of bouncing in the air.
Brake
- Braking Force Balance: 50%
- Braking Force Pressure: 100%
This balances the stopping power evenly between the front and back wheels so you can slow down safely without sliding out of control.
Differential
- Front Acceleration: 30%
- Rear Acceleration: 65%
The differential controls how much power goes to the left and right wheels. These settings allow the front tires to pull you through corners, while the rear tires help push you out of turns with minimal wheel spin.
