I’ve been doing some research on this. ABS system is not an issue because the baleno RS has the same part numbers(from Boodmo, not many technicians have information about these)for all four sensors and the module. The brake lines (hard lines) were also same/similar in size and part numbers so that won’t be an issue I guess. The brake booster and master cylinder has different part numbers but I think you can get away with the oem one on your regular Baleno. I tried to source the front disk rotors and calipers of Baleno RS from showroom but they are very costly as they are imported. Trying to get a bigger rotor and caliper in Suzuki line up as I would still like to take it for periodic services. I think the Ciaz brakes might do the job, not sure. Planning to use the front brake setup the car currently has as the rear brakes. Need to figure out mounting the caliper properly. I’m hoping the front caliper mount can be used on the rear. If everything goes according to plan it will cost under 10-12k only.
