Center Differential (AWD)
Front/rear power split for AWD cars. Higher = more rear bias = more RWD-like.
What it does
Only appears on AWD cars (DrivetrainType = 2). The number is the percentage of torque sent rearward. 50% is a true 50:50 split; 100% is fully RWD-like.
Standard track AWD lives around 65–80% (rear-biased). Drift builds push 90–100%. Rally builds sit closer to 50–60% so the front wheels can pull the car through ruts and loose surfaces. Drag setups can go either way depending on launch weight transfer.
Center diff is the *cheapest* way to change AWD character without changing chassis balance. Moving 10% forward fixes a lot of corner-exit understeer at the cost of some throttle response.
In-game controls
Center diff (% to rear)
Range: 50–100%; defaults often 70%
Raise →
more RWD-like — more rotation on throttle, risk of corner-exit oversteer
← Lower
more pull-out-of-corner traction, more on-throttle understeer
Watch these telemetry signals
- Tire slip ratio (longitudinal)slipRatioWhere: Corner panels, "slip R" — front/rear and L/RCompare front-axle vs rear-axle slip under power. Fronts slipping with rears gripping = too much front bias; rears slipping with fronts gripping = too rear-biased.
- Tire slip angle (lateral)slipAngleWhere: Corner panels, "slip A" — compare front vs rearOn corner exit: if the front pushes wide while the rear stays planted = center diff too far rear, fronts have no power to help pull through
Symptom → fix
| What you feel | Likely cause | Try this |
|---|---|---|
| AWD car understeers on corner exit | Too rear-biased — fronts have no torque to pull car straight | Shift center diff 5–10% forward |
| Rear steps out under power on AWD | Too rear-biased AND/OR accel diff too locked | Shift center diff 5–10% forward; if it stays, drop accel diff % |
| Car feels heavy on turn-in, doesn't rotate | Center diff too forward | Shift 5–10% rearward; recheck |
