Note: Like MR cars, MR-AWD cars are known for agility, but the centralized mass and responsive chassis dynamics — can make them feel unstable at high speeds, particularly on straights or through fast corners.

Even though AWD adds traction, MR-AWD cars can still feel darty, nervous, or rear-active at high speeds due to:

 

1. Rearward Weight Bias

• engine sits behind the driver → less weight over the front

• at high speeds, the front can feel too light, especially under acceleration.

 

2. Aero Imbalance

• too much rear downforce vs. front causes front-end lift

• too little rear downforce causes yaw instability or tail wiggle.

 

3. Suspension Stiffness

• too soft front = floaty steering

• too stiff rear = nervous on bumps, especially in fast corners.

 

5. AWD Torque Split

• rear-biased torque split can overwhelm the rear tires mid-corner or during acceleration, causing yaw at speed.

​

• increase forward power balance (prevents rear overreaction at speed)

• increase forward brake bias (Helps stabilize the car during high-speed deceleration by preventing rear-end lightness or rotation)

• increase front aero (keeps the front planted for high speed stability / steering)

• rear aero - balance - don't increase too much (keeps rear planted without overpowering front)

• stiffen front springs (prevents excessive lift and roll at speed)

• stiffen front damper compression (improves responsiveness and stability at high speed)

• stiffen front damper rebound (stabilizes steering)

• slightly soften rear damper rebound (reduces rear bouncing / twitchiness and keeps more stable / planted)

• slightly stiffer front ARB (adds front end stability)

• increase front negative camber (to increase grip on cornering and maintains front end control)
