Here is a decent brake set up for less that 1500.00 front and back (right at 1500 with drilled/slotted/zinc wash) 11 3/4 inch brakes with brackets, hubs and 4 piston billet calipers on both ends. Alot of dudes around here run em. I have basically negotiated their web site and landed you where you need to be. Scroll down, the first two choices are fronts next down are rears. I spoke to them and they said 1520.00 slotted/drilled/zinc. plus shipping.
