Ok, will change the front one's soon.
There's no much difference in fuel efficiency. still between 13-16 kmpl.
Gear shifting much softer than in the begining. Also the dancing gear syndrome has healed.but the suspensions make too much noise espescially after a heavy rain.but it won't bother those sitting in the cabin with windows closed.Smoke - rarely when i rev up, when there is a sudden need for speed (in second gear) i can see some black dust through rear view mirror. There's no other major issue till now. had faced some problem when the 35k service got prolonged. it had nasal fullness
that is the air filters were blocked and vehicle had very poor pick up. after the service everything got normal.
