Hi EV crowd ! After a few months driving this beast I’ve come to terms with the power and ability to not fool with the drive unit by flashing etc.. and swapping the old 400ftlb unit with the new 3.8 ratio . Can the Bolts 7.8 ratio fit the Spark ? Does the Spark have the axle attached to the motor like the Bolt ? Then you would multiply the 400 by 7.8 Holy Cow !!!! Tires are my main concern now , there are multiple Youtube videos of Chevy bringing the Bolt EV with the low resistance tires and one with Summer tires and the diffence is more than a few seconds faster on an Autocross , that would relate on the street.
