4.前底橫梁平衡拉桿（俗稱：前底吧。選裝件）
——設(shè)計安裝于前橋與車架底盤前方的連接部位。主要作用是增強前底橫梁（前橋）與底盤的連接強度，減小離心力與車身扭曲造成的前橋位移形變，其主要作用同樣是改善過彎性能；
5.后輪避震塔塔頂平衡拉桿（俗稱：后頂吧。選裝件）
——設(shè)計安裝于后避震塔塔頂?shù)奈恢蒙?。主要作用是增強車尾箱的強度，減小車廂后部由于離心力造成的橫向扭曲，減小過彎時車尾部的側(cè)傾度，提高車輛過彎性能；
6.后橋懸掛增強平衡拉桿（俗稱：后底吧。選裝件）
——設(shè)計安裝于后橋與車架底盤后方的連接位置上。主要作用是加強后橋與車架的連接強度；
7.車架（車身）底盤增強平衡拉桿（組件）
——設(shè)計安裝于車架底盤的中間部位，主要作用是加強車架底盤的整體剛性。
視車輛出廠設(shè)計，車架結(jié)構(gòu)不同，有些被省略，有些被其他的結(jié)構(gòu)取代。
家庭型車輛通常不太講究這些裝備，但運動型車輛，則寧多勿少。
此外，還有為了增強車身整體剛性而專業(yè)改裝的車身（駕駛艙內(nèi)）防滾支撐架與側(cè)門加強鋼梁等，都是專業(yè)性較強的競技必備改裝項目。
平衡桿的取材非常講究，不是普通鋼材所能輕易取代。既要求質(zhì)量盡量輕，又要求其配合車身材料的硬度，達(dá)到與之剛?cè)岵?jì)而形成一個融洽的整體。
不同底盤設(shè)計的車型，通常不能以其他車型的配件隨意代用。
發(fā)生嚴(yán)重碰撞事故后，相關(guān)產(chǎn)生形變的平衡桿及其組件，應(yīng)當(dāng)全部更換，而不是用加熱矯正就可以完全修復(fù)的，否則，即便修正復(fù)位，但材質(zhì)本身的變化，也會影響到高速行駛的安全和穩(wěn)定性。
1 Front Lower Arm balance rod (the original car essential accessories)
- Designed for mounting on the front axle and the front wheel of a separate connection, the main role is responsible for controlling the angle of the front wheels inside and outside;
(2) before the beam direction balancing rod (the original car essential accessories)
- Designed for mounting on both sides of the front hem arm, control the direction of the front wheels of the overall symmetry. Main role is responsible for the front wheel anteversion, maintain directional wheel tracking capability;
3 front suspension tower top balancing rod (commonly known as Hong Kong and Macao: the top bar. Optional parts)
- Design and installation of the front suspension tower top position. Main role is to enhance the cabin and the front body rigidity counteract centrifugal torque caused by the transverse frame deformation (deformation can cause severe tower tear), to improve the vehicle's cornering ability, improve cornering speed, reduces body affected the centrifugal force produced by the roll angle;
4 front bottom beam balance lever (commonly known as: front end of it. Optional parts)
- Designed for mounting on the front axle and the front of the chassis frame joints. Principally to enhance the front bottom cross member (front axle) with the chassis connection strength, reducing distortion caused by the centrifugal force and the body deformation displacement of the front axle, and its main role is to improve the cornering performance of the same;
5 rear shock tower top balancing rod (commonly known as: Rear top bar. Optional parts)
- Design and installation of the rear shock tower top position. Main role is to enhance the strength of the boot, the rear compartment reduces lateral distortions caused by the centrifugal force, reducing the rear of the vehicle roll when cornering, improve vehicle cornering performance;
6 Rear axle suspension enhanced balance rod (commonly known as: after the end of it. Optional parts)
- Designed for mounting on the rear axle and the rear of the chassis frame connected position. Main role is to strengthen the connection of the rear axle and the frame strength;
7 frame (body) Chassis Enhanced balance lever (assembly)
- Design and installation in the middle of the chassis frame, the main role is to enhance the overall rigidity of the chassis frame.
Depending on the vehicle originally designed, the frame structure is different, some have been omitted, some have been replaced by other structures.
Families usually do not pay attention to these types of vehicles and equipment, but the sports car, then rather more not less.
In addition, in order to enhance overall body rigidity and professional body modification (cockpit) to strengthen anti-roll support frame and side door beams, etc., are highly specialized athletic necessary conversion project.
Balance bar drawn very particular, not ordinary steel can be easily replaced. Requires both quality as light as possible, but also require their hardness of the material with the body, with firmness and flexibility to achieve the formation of a harmonious whole.
Different chassis design models, usually can not freely substitute other models of accessories.
Serious collision, the associated balance bar of deforming its components, should be fully replaced, rather than the heating can be completely repaired correct, otherwise, even if correction is reset, but the material itself changes, will also affect a high-speed safety and stability.
