i have 1.5 Aspire. top speed is 197Km.
emergency breaks work well till 120 or you can say 130 ( handleable in normal conditions ) with CC5 195-65 tyre profile 2 person on board
140 to 150 breaks work fine or you can say just ok with CC5 195-65 tyre profile 2 person on board
i was on 190 suddenly mehran guy change his lane without indicator and that moment was horrible. i pressed break pedal and from few MicroSec i feel like my feet or break pedal is jammed with with each other and i was trying to take my feet off but that few little moment i was unable to do. don't know the reason but ALLAH save us. we were 2 person on board was just trying to cross 197 we were on motorway M2.
so i Believe Aspire or Ivtec both break as same. Do not Drive Above than 120 or maximum 140.
about handling is good enough till 180. i drive about 50 Min continuously on 180km ( plus, Minus 10km ) so it's good. but when Allah Na kare you have press hard break for sure will be in huge huge trouble !!
