卡鉗6活賽 - 汽車改裝

※ 引述《VictorG37 (快約我出去玩吧~)》之銘言：
: 請問板上專家
: 若要換6活塞..卡鉗的話,是否碟盤要跟著換呢?
: 加大碟的通風碟?
: 大4,大6,小8等等...哪一種比較好呢?


好喔 願聞其詳
最最最最簡單的 我不知道妳們有沒有玩過GT5
有玩過的人難道不是因為換輪胎 剎車距離才會減短嗎...
要是加大卡鉗改剎車可以減短剎車距離 那應該要有個"剎車改裝"的項目

國際大廠Stoptech的網站

第二段第一項:
"1) The brakes don't stop the vehicle - the tires do. The brakes slow the
rotation of the wheels and tires. This means that braking distance measured
on a single stop from a highway legal speed or higher is almost totally
dependent upon the stopping ability of the tires in use - which, in the case
of aftermarket advertising, may or may not be the ones originally fitted to
the car by the OE manufacturer."

如果看不懂 簡單翻譯就是
"是輪胎把車子停下來 不是煞車
剎車是把輪圈跟輪胎的轉動慢下來 所以距離測量最大因素取決於所使用的輪胎"


剎車工程師James Walker Jr說到

這就是物理
d = V2/(2g(f + G))

Where:
d = Braking Distance (ft)
g = Acceleration due to gravity (32.2 ft/sec2)
G = Roadway grade as a percentage; for 2% use 0.02
V = Initial vehicle speed (ft/sec)
f = Coefficient of friction between the tires and the roadway

注意到它完完全全沒有提到剎車蝶盤或者是煞車卡鉗嗎?

[因為是輪胎使車子停下來 不是煞車]

他寫道的
http://0rz.tw/eL0pI
"Brake system modifications have their place to help make your ride more
consistent, predictable, and user-friendly; however, if your ultimate goal is
to decrease your stopping distance, look no further than the four palm-sized
patches of rubber connecting your ride to the ground."

"結論 換輪胎吧"

有一期美國的人車誌[car and driver]提到
http://0rz.tw/m2tLe
"The 911 with the PCCB system performed about the same as the other 911 and
the Vette. The average stopping distances of the two 911s were within a foot
of each other (305 feet), not surprising since both cars were wearing the
same tires. The Corvette averaged 326 feet. The conclusion: PCCB buyers enjoy
a 37-pound weight savings but not necessarily more robust brakes. "

"911的PCCB剎車系統與其他擁有普通剎車系統的911和corvette的剎車距離幾乎沒有差異
差異都在一吋以內 但是他們都有相同的輪胎
所以呢? 買PCCB剎車系統的車主享受了37磅的輕量化 就這樣"





就是這樣
改了煞車只是讓你"覺得"距離更短
只不過是因為你踩下去的"回饋"跟OEM不一樣

只要剎車鎖死 或者啟動了ABS 那再好的剎車也沒救
