i built my own from scratch... made my own caliper brackets to fit the rotors I choose and the calipers I bought...

the front was a straight forward shot...

the rears however took a little engineering and 2 trials before i got the fitment i liked.

front calipers are 600 ea new
rear calipers are 140 ea new
Front 2 piece Baer rotors 575
Rear 2 Piece Baer rotors 550
Materials to make custom Steel Braided Brake Hoses 125ish
Front Pads 75
Rear Pads 55
Brake Fluid 27

Aluminum to make brackets 30

in all cost me around 2-2250$ but that includes the GSX master and Wilwood Valve to adjust F/R bias

vs stop tech which is like 2500 for just the front kit

I picked the front calipers off a buddies M3 that got trashed at the track, they are Stainless Thermlock pistons so i just made sure they held pressure, other then a few exterior scratches they are mint, got the pair for 600, where as wilwood wants between 6 and 625ea.

the rears were brand new out of my 72 Trans Am kit I had laying around
4 piston dynalite same calipers they use for the front kit for the eclipse.
