3.0 Two Piece Brake Rotors The Viper SRT10 is known for having world class brakes. The 2008 Viper ACR takes this incredible braking system to the next level with the Stop Tech two-piece lightweight slotted rotors. These brake rotors significantly reduce rotating un-sprung mass. They also improve brake cooling and reduce on-track fade.  AUTION: The slotted rotors may increase brake pad wear depending on C driving conditions. These rotors may also produce some additional brake noise due to the high performance two-piece construction. It is normal for the brakes to make some popping or creaking noises as they cool down. This is the result of the two-piece construction. Although the brake rotors are a two-piece construction, they should be replaced as a complete assembly.  AUTION: During brake pad replacement the pads must be loaded so that C the wear sensor is on the inboard side of the caliper and the trailing side of the wheel rotation (all four wheels).
