Well, I am currently parting out a '97 firebird and with my desire to bring my Z into the 2000's I have been thinking of trying to adapt the firebird's ABS into the Z.
As I see it there is only one problem with accomplishing this...the wheel speed sensors. All other components would be cake to bring over to the Z. You could easily adapt the Brake Modulator (ABS), EBCM, Brake Combination Valves, etc...but the foreseeable problem is that the wheel speed sensors are built into the wheel hubs. These send a frequency to the EBCM, giving it information on possible wheel lockup.
I was wondering if anyone has tried to adapt these speed sensors to accomplish this?? An interesting idea nonetheless....
