This is the front-axle pad from EBC's Yellowstuff line, fitted to the 6.2-liter C6 Grand Sport (2010–2013). The manufacturer describes Yellowstuff as an aramid fibre-based brake compound with a high brake effect from cold, so the pad bites on the first stop without the warm-up that race compounds usually need. For Grand Sport owners who want more fade resistance and stopping power than stock pads give, this is a street-focused upgrade with a documented formulation behind it.
The manufacturer states that high friction formula improves brake effect by 15%, and it lists a green fade threshold of 400°C (750°F), which it ties to the maximum temperatures expected in fast street driving. It also no longer recommends Yellow for dedicated track use, so buy these for spirited road driving rather than full-time track work. The pads are fully shimmed, slotted and chamfered, and a Brake-In coating helps them seat after installation.
Plan on a few hundred miles of gentle use before hard stops, because bedding happens naturally in the first 100-200 miles of urban use according to the manufacturer. Owners on user forums describe the Grand Sport calipers as fixed, not floating, and say the pads are held by star-head pins that often strip, so bring a Torx T45 socket and a fresh set of pins. Search terms this product matches include C6 Grand Sport 6.2 front pads, Corvette aramid street brake pads, and ECE R90 Grand Sport brake upgrade.
The manufacturer no longer recommends Yellowstuff for dedicated track use, though it notes that the compound can still be used on lighter cars in track driving, and that it needs a longer bedding procedure before track use.
Owners on user forums describe two approaches on the Grand Sport: some remove both large caliper bolts to reach the pads, while others report that the pads can be changed without removing the caliper. Confirm the procedure against the manufacturer's guidance before you start.
Owners on user forums report that a Grand Sport pad swap takes about half an hour once the wheels are off, and that the work is mainly a matter of clean-up and pin removal. Expect to use a T45 Torx socket, a 3/8" torque wrench for the pin bolts, and a 1/2" torque wrench for the lug nuts. Compress the pistons slowly with a C-clamp, and never pry against the rotor. Watch for seized or stripped pin bolts, since owners on user forums frequently report damaging them, and support the caliper so the brake hose is not under tension.
