the car has 4g15 in it and trust me it doesnt feel underpowered. combine that with a CVT and the car's acceleration is simply sweet. it is not as good as the baleno but i am not complaining.
the thing about the tire size is that its not 165/60/r13 but 165/r13/6PRLT. so i dont know the exact overall diameter. i did a rough estimate by putting a 185/65/r14 next to it and they seemed to be of the same size. i am also thinking that since the original tire has 6 ply rating, i should look for a tire with some good weight carrying capacity.
i think i will visit chah sultan one of these days to check for lancer rear seat and its fitment. hope its bolt on fit cos i dont wanna do any alterations to the car.
i am also looking into the possibility of finding the 4g15t version of the engine but thats for a much later stage.
