as for an engine that is 796cc there is no need for serva to be installed as that chasis is not this much poweer full to tackle with a serva..
if u wanna good road grip that change mehran 12" rims with alloy rims 13" and 175 65 13" tyres of dunlop .. its expensive around 24000 but the grip will be excellent .. no need for serva
if u want a cheap solution then go for serva.. it will cost u around 3000
Second alternative is go for a 4 wheels disk brake that will cost u around 5000 - 7000 thousand
but for both too much modifiaction is required...
I HAV CHENAGED THE RIMS N TYRES TO 13" N IT WORKS EXCELLENT .. REALLY EXCELLENT
