What do you do when you have a pretty lightweight 4 cylinder car and you want to go faster? Well you make it even lighter! The idea is to shed a couple of hundred pounds on the car before changing the rear differential gearing and slight motor tweaks. The car feels a little more peppy now with around 80 pounds of weight shed from the rear trunk of the car. The lightweight battery took off around 30lbs in it self. Which is awesome! Also the tires are a little less height than the tall factory 14 inchers which makes the gearing feel more responsive also.
