the mpsc s1 kit is availible for both the front and the rear. i have both. the color that you're chosing is the hat of the rotor, the kit does not come with new calipers.

honestly imo the big brake upgrades are a waste of money unless you're doing it for show or you do some serious road racing. it's like $1200 for the kits and you stop a whole 8" or sosooner.

in all honesty, you're just fine getting a replacement set of stock rotors and just putting a really good pad on there. hawks are a popular choice and not too expensive. i'm running porterfields and have been very happy with them. i have a friend that's really big into autox and road racing and he swears by stock rotors and good pads. if they can handle limerock they're fine on the street.
