idsi doesnt hav any stability problem if u dont drive like u stole it...drive decently,nd its not gonna skid anywhere...i hav it for 3 yrs,hav done 115000kms on it,its very very reliable...its quiet,its comfortable,its drive is smoot,gives pleasure,specially the Electronic power steering makes life very easy...as a teenager,i hav been doing alot of rash driving stuff etc etc on my idsi,but i knew its limits nd i never tried to cross them...so i never ever had braking nd stability problems,the car never skids...earlier i had 195 sized tyres,nd believe me even if i wanted it to slip,the car didnt...i just loved its handling,i used to change lanes wud a jerk on steering wheel at speeds of 100km/h +, still no slips... a frnd had a corolla nd he was driven crazy that how could i do stuff like that wid only upgraded tyres? also keep in mind that my car is higher then normal idsi due to the spacers installed to lift the car after cng cylinder was put in...
now im back on 185 size tyre but handling is still very nice...nd those who think that the company gave 165 tyres on city bucz they calculated everything out are totally wrong...they put smaller tyres just to save some $$$...nothing else...
