Note: Snap oversteer is relatively common in FR cars, especially high-power or lightweight models. Snap oversteer happens because most of the weight is on the front axle, while the rear wheels handle both acceleration and lateral grip, making them more prone to breaking traction suddenly.

​

Causes

 

• Abrupt throttle lift mid-corner: shifts weight forward thus unloads rear tires suddenly

• Too stiff rear suspension or rebound: rear can’t absorb load transfer so breaks grip violently

• Tight LSD or diff lock: both rear tires rotate together so lose grip together if one is overloaded

• Light rear end (weight bias): less inertia at the rear so harder to control once rotation starts

• Stiff rear ARB / soft front: rear rotates too quickly without front-end support

• Cold or overinflated rear tires: reduced grip so unpredictable breakaway

​

Fixes

​​

• shift brake balance forward (educes the likelihood of the rear stepping out under braking)

• soften rear springs (to allow the rear tires to maintain better contact with the road)

• soften rear damper compression (to prevent the rear suspension from reacting too harshly to bumps and weight shifts)

• soften rear dampers rebound (to slow the rear’s return to equilibrium, making transitions smoother)

• soften rear ARB (reduces lateral stiffness, allowing more compliance and reducing the tendency to step out)

• stiffen front ARB (increases front-end stability, preventing the rear from becoming too loose)

• increase rear aero (helps stabilize the car at high speeds and during cornering)

• increase rear negative camber (mproves grip in corners, reducing instability)​
