🏎️ Traction roll — tips over in high-grip corners
The car trips over its outside tires and rolls in corners when grip is high.
If the car pulls one way, behaves differently turning left than right, or this started right after a crash, the cause is probably mechanical rather than setup — and no change below will fix it.
Run the 12-minute mechanical check first →Try these in order
Make one change at a time and re-test — that's how you learn what your car likes.
-
1
Widen the track (front and rear)
A wider stance resists rolling over.
-
2
Add / stiffen sway bars
Directly limits body roll that leads to the trip-over.
-
3
Thicker shock oil
Slows weight transfer so the chassis doesn't lurch onto the outside tires.
-
4
Harder / less aggressive tire
Slightly less peak grip removes the trip point on hot tracks.
-
5
Lower the ride height / centre of gravity
Less leverage to roll.
-
6
Stiffer springs
Reduces roll angle.
