ERA Rear Suspension Calipers/Pads

[Dangerous Doug]

Many, many fine fun miles on my ERA 289FIA. Now it's time to replace the brake pads. I am looking at some Baer ceramic pads, and for the rear 97 Camaro calipers there are two choices, the only discernible difference being the price:

$82.49/set
Product Line: Baer DecelaPads Brake Pads
Summit Racing Part Number: BHI-D0413
FMSI Reference Number: D213/D295/D413

$118.49/set
Product Line: Baer DecelaPads Brake Pads
Summit Racing Part Number: BHI-D0295
FMSI Reference Number: D213/D295/D413

Anyone know which will fit the ERA outboard brake calipers (97 Camaro).

My current rear pads produce a lot of dust, so I am looking forward to having cleaner wheels. Also, "set" = four pads, two for each side??

Same issue on the front, really, for the 70 Camaro SSBC calipers I am using. Two different Baer brake pad sets, but these have different FMSI Reference Numbers:

$64.49
Product Line: Baer DecelaPads Brake Pads
Summit Racing Part Number: BHI-D0052
FMSI Reference Number: D52/D122/D313

$95.49
Product Line: Baer DecelaPads Brake Pads
Summit Racing Part Number: BHI-D0154
FMSI Reference Number: D138/D154/D202

The SSBC calipers should use the stock pads, if I recall correctly. Anyone know which of these would be correct? And what the hell is the FMSI?
