why are u gonna get slotted? slotted rotors are for hi-end use only as the slots actually have a sharpened edge on them that scrapes the brake pad clean on each turn and obviously at the same time scrapes the pad itself making the brake pad life considerably shorter, that and it really doesnt have any advantages in street use over cross drilled since cross drilling does a fine job of keeping the rotors cooler(the whole point in crossdrilling or slotting in the first place)
You can get 4 eibach cross drilled rotors off of ebay for under 200 and then just get some good pads from rr-racing likw was mentioned above.
Otherwise if money really isnt an issue I would go with a wilwood or other reputable big brake kit made for our cars. those should come with rotors, calipers, pads, all the lines including upgraded SS brake lines.
