SSBC is Stainless Steel Brake Corporation (Corporation? Company? Something like that.)
No mods are necessary. Bolts right in to the brackets supplied by ERA.
The "clicking" of the Camaro brakes: I actually spoke with a guy at my local auto store that was a trained Chevrolet technician. Their actual Chevrolet shop manual says to take a chisel or a punch and smack the "ear" of the brake pad to deform the edge and thereby close the gap between the pins and the "ear". This sounded a bit hokey to me, but the guy swore that it was right in the Chevrolet manual for that era of brake caliper. You'd think somebody would just change the design on the brake pads...
SSBC's weren't cheap. I think I paid around $400 for mine.
I don't consider the upgrade necessary, but it is nice. Plenty of guys are using the Camaro brakes on the 427. For me, that "clicking" noise just drove me nucking futz!
Here is exactly what I bought:

They don't "click". Pedal travel is better. I like them.
