requirements of the GT-R, the sequential 6speed dual clutch transmission is unlike a typical automatic transmission. You will likely hear mechanical sounds from the transmission, particularly at slow speeds and at idle. This condition is normal. driving, or through the continued use of the brakes, the disc rotors must be replaced. Brake dust This vehicle is equipped with high performance brakes, and the characteristics of the brake pad material may cause more brake dust than other vehicles. NISSAN recommends a wheel coating that helps prevent the brake dust from sticking to the wheels. Contact a GT-R certified NISSAN dealer for more details. BRAKE SYSTEM INFORMATION Cracks on brake pad The friction material of the GT-R disc brake pad is bonded to the pad backing plate more strongly than conventional brake pads to withstand the high brake temperatures. The friction material and backing plate expand due to heat at different rates. Some cracks may be on the surface of the friction material due to the differences in expansion rates and the strong bond between the friction material and backing plate. The cracks do not indicate the brake pads need to be replaced. However, depending on the condition of the cracks, the pads may need to be replaced. Contact a GT-R certified NISSAN dealer. DRY CARBON FIBER REAR SPOILER (if so equipped) Cracks on the disc rotors When the brake is repeatedly applied at high loads during the cold season, small cracks of approximately 0.12 in (3 mm) long may appear A . This is due to around the cross drilled holes * the temperature differential that occurs because the surfaces of the disc rotors become hot while the inside of the rotor is still cold. However, this poses no problem in terms of brake performance, and does not indicate a malfunction. The brakes do not need to be replaced. However, if the cracks extend to 0.16 in (4 mm) or longer after repeated application of the brakes at high loads during high performance The surfaces of the dry carbon fiber rear spoiler are lightly coated like a race car so that you can feel the proper texture of real carbon, which may feel rough. This is normal. GT-R Overview GTR-27
