i think my spinouts were caused by driving around corners while on throttle to much, i hit some ice out of no where and once you lose it completely its alot harder to get the car to stop than if the brakes locked up while the car is going straight. even though i had snows on the rear, they were wintermark magnagrips (shittiest snows made) i think with some dunlop graspics on a car[all 4] ( good performance to cost ratio) it would be no problem to have a fun rwd car in the snow
