probably a little of each. little wider, 10mm front and rear. little stickier, r-comps. less weight, 6lbs a corner. diameter stayed the same. i just think that my handling and acceleration are more greatly influenced by the dynamics of the tire to road interface than by my unsprung weight. each corner still weighs close to a 100lbs if you count rotor(25lbs), caliper(15lbs), pads(2lbs), tire(26lbs), wheel(22lbs), and studs(1lbs). so 6lbs is roughly 6 percent reduction and nt01s are im safely guessing here providing more than 6 percent better traction. every bit does help though.
