you have a few options , but if you want the headache free version , heres what I did .
find the complete 03 brakes set up , ie spindles , hubs , rotors , calipers and brake lever/ master cylinder set up , and bolt them onto your blasty , now keep in mind , you will have a lot of trouble getting the old spindles off your stock a arms because of the abuse they get , mine were impossible to remove from the lower ball joint , and i ended up cutting the spindles off and i decided hell with this , and i'm going with aftermarket a arms because the stock a arm ball joints are not removeable and they aren't serviceable . so when they get sloppy it means you need to find new / used stock a arms , or aftermarket a arms . aftermarket a arms are better because you can remove the ball joints and replace them when they become worn. big savings on overall maintenance . for 520.00 you can get a great set of asr arms off ebay , and you'll be very happy with them
