bigger brakes in the front and drums in the back will perform fine. won't look very cool - but will work fine. if you go this route, please don't paint your drums yellow.

i used the fastbrakes kit for a dx and it allowed use of the stock brake lines. their website lists a kit for the ex/si, also. you may want to call them ask for brian hasty - the owner. nice guy. he prototyped these kits, all by himself, many years ago and can provide more silly details than i'm capable of.

i have a fastbrakes kit i might sell, if any of you guys is looking. got the front and the rear, actually. don't know if they still sell the rear kit (12" rotor with stock caliper).

(booster/mc and prop valve will need upgrading if you decide to go disk/disk.)
