(The Aero4 Calipers are NOT available in the piston sizes we need for balance). The Superlite caliper works well with 3.00” or less of piston area. For Manual brake cars & trucks, we upsize the piston area from 1.98” to 3.00” to achieve a strong braking package. BP-10 brake pads are standard & make a good street pad. For Autocross, I recommend purchase a set of Wilwood “E” pads. For road course track days, you’ll need Wilwood BP-20’s or higher level race pads to handle the heat.
