front viper brakes on my duster

i have $750 in the whole works. of course i did make the mounts for the calipers and turn the factory rotors off myself. i didn't really care about the wieght savings,the difference in braking is well worth it if it is heavier. the only way to save anymore wieght is to use aluminum hubs,and then i don't think it would be worth it unless you were competeing in road racing or something. dr.diff helped me out a bunch on it with getting it all together.
how big are your rotors?
