🏎️ Understeer / push — won't turn in
The front washes wide and the car won't rotate into the corner.
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
Thinner front shock oil
A softer-reacting front loads the front tires faster for more bite on entry.
-
2
Softer front springs
Lets the front end squat and work the tires through the corner.
-
3
A touch more front toe-out
Sharpens initial turn-in (too much makes it darty, so go small).
-
4
Stiffer rear (thicker oil / stiffer springs / add rear sway bar)
Reducing rear grip lets the back rotate and kills the push.
-
5
Less rear toe-in
Frees the rear so the car steers more.
-
6
Move weight rearward (battery back)
Unloads the front slightly and helps rotation.
