first of all get ur cultus efi some nice alloy rims 13 with dunlop eco etc brand then check its grip n brakes
secondly u have o change its brakes bush pedals or wat eva it it after 20, 000 km
now race with any auto vitz it will surely beats it, i dun know abt manual vitz but if u compare the engine
cultus efi got same sort of engine as 1.6 gti baleno gots
its 4 cylinder , 16 vale efi
while vitz 4 cyliner , 12 valve efi
so cultus rockssssssss much lighter in weight more aero dynamic shape, more acceleration ........
