討論到sway bar的功能，這一段是 wiki上的 http://en.wikipedia.org/wiki/Sway_bar Main functions Anti-roll bars provide two main functions. The first function is the reduction of body lean. The reduction of body lean is dependent on the total roll stiffness of the vehicle. Increasing the total roll stiffness of a vehicle does not change the steady state total load (weight) transfer from the inside wheels to the outside wheels, it only reduces body lean. The total lateral load transfer is determined by the CG height and track width. The other function of anti-roll bars is to tune the handling balance of a car. Understeer or oversteer behavior can be tuned out by changing the proportion of the total roll stiffness that comes from the front and rear axles. Increasing the proportion of roll stiffness at the front will increase the proportion of the total load transfer that the front axle reacts and decrease the proportion that the rear axle reacts. This will cause the outer front wheel to run at a higher slip angle, and the outer rear wheel to run at a lower slip angle, which is an understeer effect. Increasing the proportion of roll stiffness at the rear axle will have the opposite effect and decrease understeer. 因為美規k6只有前防傾，沒有後防傾，所以裝後防傾有助於改善understeer 我是基於這樣的紙上研究，裝完也有感覺改善（希望不是錯覺） 我想那段文字應該是說前後兩外輪的camber不一樣導致slip angle 不同，至於什麼roll center那一大堆的我還沒搞懂， 想去圖書館借本書來研究，網路上的東西圖好少Orz -- 有人常問我為什麼喜歡唸數學，我總是說：「興趣啊!」 其實我心裡是這麼想的。如果我年老的時候如果我跟孫子說：「爺爺 當年的電子學、積體電路設計學的很棒。」 到時候他們頭上大概會升起一堆問號，因為到那個時候這些東西早就不知道去哪裡了。 可是如果我說：「爺爺當年學了高微、機率論、實變數論、拓樸...」 他們一定會跟我現在的同學一樣，眼睛瞪的大大地說：「幹!你是瘋子嗎？」 --
