Are the ABS rings on the S chassis on the axles or on the rotor? Basically I am wondering what the differences are between the ABS and non-ABS rotors, and whether or not they are interchangeable. I -believe- there is some minor difference in size as well? Any info greatly appreciated. ---

abs is not compatable with non abs. the non abs rotor is a different size and has a different part number when ordering GT ---

So if I were to put non-ABS rotors on (in theory only), I’d have to change the calipers and pads accordingly? ---
