Runs wide on power
The diff is locking the rear axle as you feed in throttle, dragging the car straight. A differential symptom far more often than a suspension one.
Ranked on a free car
This week's rookie circuit is free — these labs open with this symptom at its key corner, already ranked. What is free this week.
The default order
Generic order — open a lab for your car and corner.
- 01Less drive (acceleration) diff lock5–10%diff
A tight drive ramp forces both rear wheels to one speed under power, pulling the nose wide.
Less traction out of slow corners; more wheelspin.
- 02Less diff preload1–2 stepsdiff
Preload keeps the diff partly locked even at low torque — exactly the state you're in on entry.
Vaguer feel at low steering angle.
- 03Later, smoother throttle½ secondtechnique
Getting on power before the car is pointed is the most common cause of this and costs nothing to fix.
None — try this before any setup change.
- 04Wait for the wheel to come back½ secondtechnique
Power applied with lock still on pushes the car straight on, because the front cannot both turn and resist the shove.
None — try this before deciding the car will not rotate.
- 05Give up the entry for the exit5 km/htechnique
A slower, tidier entry lets the car point earlier, and pointing earlier is what lets you use the throttle sooner. The straight pays it back.
Feels wrong in isolation. Time it over a full lap, not into the corner.
- 06Softer front anti-roll bar1 clickbar
Lets the front axle roll and build slip angle, adding front grip as the car takes its set.
Slower initial response; more roll to wait through.
- 07Lower traction control level1 leveldriver
If TC is cutting early the car feels like it's pushing when it's actually being throttled back.
Requires cleaner throttle work.
- 08Shorter gearing1 toothdriver · adv
If you're bogging out of a hairpin the car pushes because it isn't accelerating, not because it's mis-balanced.
Costs top speed.
