I haven't ever heard of this before, but it would be cool if they were offered.

This was never an option as far as I know(at least for Oldsmobile H-Bodies). The cost to convert would be prohibitive, and the true benefits would be nill. OK, it would LOOK cool.

4 whl disks were available on Riviera/Reatta (E-body) of the period, do not think it would be a major effort to swap but would also need the multi-strolke parking brake and 4wd proportioning valve and master cylinder. Might also have trouble exchanging the coils for a transverse leaf spring (might need to swap the gas tank also) to do it all. But may just be able to swap the knuckles and calipers.

My question would be why ? Have found little difference in stopping power (have both on same weight vehicles and same size tires (225x60x16) and both stop extremely well. Rears on FWD cars do not do very much anyway.

Of course if just for show, should be simple

well if it wont enhance braking performance, I wont bother. Thats a lot of work just for a coolness factor LOL. I always thought 4 wheel discs stopped better

4 wheel disk brakes do stop better in certain situations such as on a race track where brakes take a beating. But for normal stop and go around town and the occaisional "panic" stop on the highway, our disk/drum setup is more than adequate. For a "cool" look, you could paint the drums with a special hi temperature paint(like RED )or match the color of your car if you have wheels that show off your brakes.

{edit} I just saw this in the detailing section

http://www.bonnevilleclub.com/forum/...ic.php?t=17325

I guess you could apply the same technique to the drums as well
