Are you looking for Viper Calipers?

Look great. Those are really nice calipers. They have a nice fell to them and there are plenty of pad options. They work on the 11.75 B body rotors with spacer or on the C body rotors without a spacer. They'll also work on rotors up to 13 inches. I ran them on Viper rotors on my B body car and on a buddy's A body car. We just redrilled the rotors for a 5x4.50 pattern and bolted it together. Worked great, even for road racing.
