I know that i used the Baer Track kit on another car that i had and it made a pretty big difference. I have seen them go for around $700 and they come with 13" rotors and dual piston calipers. Actually same PBR calipers that come on the Cobra & ZR1 Vette if I remember correctly. For the money the Baer kit was very nice and came with the stainless braided line,hubcentric rings and billet caliper adapters.
