Abstract

Can an everyday commuter car obtain this excellent race car performance, while keeping its practicality and commuter car comfortability? A car’s performance for competitive automotive racing events is strongly influenced by its handling ability, which is affected by its suspension. Modifying a car’s ride height would affect its comfortability and performance (Sherman 2011). I believed that utilizing adjustable coilover suspensions would advantageously increase an old car’s handling capability. The automobile I lowered obtained a lower center of gravity height, sharper handling characteristic, (Bonk 2013) and less automotive body roll— the weight transfer of the vehicle while turning in a corner; however, the lowered car also resulted in a harsher ride quality. The performance and comfortability of the modified ride height was tested in a controlled environment, where the vehicle was evaluated for its average lateral acceleration throughout a cornering test, collected by an Arduino microcontroller and accelerometer. The suspension height with the least body roll and least lateral acceleration was deemed the better handling and performance suspension set-up. The comfortability part of the suspension height adjustment was tested through a ride quality evaluation, because real roads conditions are not perfect. The vehicle traveled across everyday road obstacles, such as speed bumps, dips, and imperfect roads, while the vertical acceleration inside the car was measured for further evaluation of comfortability. After I found the different suspension heights, where one resulted in peak performance and another resulted in peak discomfort, I balanced both acceleration data to determine the ideal ride height.
