Abstract:

This research focuses on how to improve racing car vehicle performance. Some studies related to this area has already done and applied for real racing eld. However, many people do not familiar with how to improve racing car performance. There are many elements which affect racing car performance, such as aerodynamics, suspension and tyre, etc. Therefore, this research include these three objectives as follows; to understand basic vehicle performance, to nd out elements which affect vehicle performance and how these affect for the performance, and to study deeply about suspension and tyres, such as placement of tyres. The reason why this research focuses on tyre and suspension is these elements are included primary set up for racing car and derive engine power and steering input to road surface. These elements set up are stated in this paper with a case study.This research proved that vehicle performance has been improved by adjusting some vehicle elements while comparing with case study, collecting and analyse data.
