I think 14 inch rims would be too much for khyber. The stock size is 12,you should go for 13.
I also own a Suzuki Khyber late 1999 model. I want to change its brakes. They are not so good. I have changed the brake padds, applied tool on discs from khiradia but I am still not satisfied. At times they also becomes very hard when they are hot. Its very dangerous. Do tell me the price of 4 wheel discs brakes.
Apart from that. the car is excellent. Cultus,alto,cuore,santro,vitz dont match this car. Excellent fuel economy and pick with spare parts availabilty and good resale.
