Wait what? Let's look at some physics here.
If you have less grip in the front, your car understeers, you hit the tree and you die.
If you have less grip in the rear, you ovesteer, you hit the tree and die again, not seeing what killed you.
1. Rear end Grip
Shocks are important to maintain the balance of the vehicle in a turn and ensure contact of the tire with the surface as much as possible. When shocks are no longer performing as expected, wheels would bounce, reducing the time of contact and thus available grip.
2. More rear end grip
Once wheels are bouncing, the tires would ge tout of round pretty quickly causing even more bouncing, road noise, grip issues.
3. Chassis balance
If you would hit a pothhole or a bump in a turn, your car chassis would bounce uncontrollably for some time causing all kinds of unusual forces on your chassis. You are risking spinning off into a ditch and potentially rolling your vehicle.
