I mean.. not to sound like a d-bag or anything, but it's quite obvious. It's interesting that a lot of people think it's all about your horsepower and torque numbers. But on the track, you're brakes play a significant factor in you're performance and times. Brakes and tires are extremely key. Not only just changing pads and rotors, but changing the fluid, brake lines, even adding cooling ducts for your brakes help a great deal.
