What is the purpose of a strut bar?
2 Answers
The function of a strut bar is to enhance the rigidity of the vehicle body, preventing deformation, and to reduce excessive body roll and loss of control during fast cornering. Below is an introduction to strut bars: 1. Strut bars are primarily installed on the front suspension of sedans. 2. To many, a strut bar may seem like an inconspicuous rod, but its effect on improving handling is arguably the most noticeable among all modification projects. 3. After installing a strut bar, although it does not alter the stiffness of the sedan's suspension, connecting the two front suspensions together increases the rigidity of the front part of the vehicle. During cornering, the two front suspensions can utilize the rebound force generated by the twisting and stretching of the strut bar to suppress body roll.
I've been driving modified cars for many years. Things like strut bars are mainly installed to reinforce the car's chassis frame. For example, during high-speed cornering, the body won't twist or shake too much, making the car feel more stable with noticeably more precise steering. Especially for the sedans and SUVs we drive daily, the factory body rigidity often isn't sufficient. After installing a strut bar, the handling improves significantly, and it can also reduce tire wear to extend service life. It makes track days even more exciting sometimes. However, you should have it installed professionally—don't mess with it yourself and risk affecting the warranty. Overall, it's a great thing to boost driving confidence, not flashy but extremely practical. I recommend it to friends who enjoy pursuing better handling.
