If you want to see one installed try Chris Moberg's site at vintagesaab.com/sonett/index/htm. His sonett named "yellow thunder" has a set of these. If you drop him a line he's sure to help you out with the particulars. You might also try Jack Lawrence at MSS in New York. He has raced a SCCA sonett with the same brake up grade for many years.|

Seems hard to believe these days! Paul Darlington's definitive article on preparing rally 96s from CCC in 70s recommended leaving the rear shoes as standard to give a bit more "bite" at the rear, effectively giving a slight bias to the rear. What you can do depends of course on your regs, but I'm not aware of anything special being homologated.
Best advice if you are stuck with Group 1/2 homologated parts is make damn sure everything you have is working properly, right back to basics like use decent fluid and good braided hose. If you left foot brake a lot you may need a vaccuum tank to maintain servo vaccuum with an open throttle.
