Is it possible to install driver seat height adjuster in VXi model. Can the mechanism be fit on to the seat or does the seat itself has to be be changed?
Seat has to be changed. Many have done in lower Swift variants (fitted Zxi seats) and I think Ciaz would also have a similar process.
chairmansaab - Then what is the point in going for 17"?
I don't think it is wise to disturb ABS setting and take the risk of tyre scraping just for that extra inch, when the tyre size remains the same.
Since there is no other middle value, the tyre size has to be either 45 profile or 50 profile. Here we shall stick to the one which results in lesser overall diameter difference. So 45 profile is more favourable.
aryans3012 - 215 section would be too wide for the car. Believe it or not, chances of scraping would be very high and reverting back to stock or a different setup means a minimum loss of 10k. On bad roads, 40 profile would prove too harsh for the suspension and other components. A lower profile would mean that your alloys have chances of cracking/breaking due to potholes, etc..
