Metro rear disk brake conversion possible?

Is it possible? What steps would one take?

Oh I'm still kicking myself for not getting this:

But...I just became a father so my money has other priorities =)

PS - I'm new to this forum, just wanted to add. I like my Metro, sure it's underpowered, but still fun to drive. It's a silver 1990, I bought it in April 99 with 76K miles, I'm the second (and final) owner! Kinda lucky eh? I added a sunroof, a very worthy upgrade, looks sharp, also a hood protector (like a bra but only covers the front edge of the hood, where it was rusted right through), and tinted windows of course. At 113K now and still starts and runs like the day I bought it!

Hey. Yes, you can do the rear disc conversion. You'll need...
Rear suzuki swift GTi spindles and hubs
parking brake cables
rear calipers and rotors

What would be easier, is just buying the whole piece that attaches to the control arm from the junkyard, and then the parking brake cables.
It's really easy to do. Hour or 2 at the most. If you want one of those cams, I know the guy who makes them, and I can hook ya up with him.

lOl. Hahaha...on a metro.
