Hello all,
I have searched here and Googled and have found very little real-world acceleration test results for the difference between heavier and lighter wheel and tire combinations. Most of what I have read has been rules of thumb, estimates, and repeated figures with no actual data to back it up.
Does anyone have real world acceleration data for 0-60 or 1/4 mile et comparing stock wheels/tires with light weight wheels/tires? Same day, same surface, same tires with only change being the wheels would be best.
I currently have the PP1 wheels with stock size MPS4S. When the tires are done, I plan to go with either the MPS4S or Indy 500s for the front and Nitto 555RII (275/40-19) for the rear. I am also looking at the SVE R357 19x10s for front and rear with one of the above front tires (265/40-19 front) and Nitto 555RII 275/40-19 for rear. That combination would reduce weight by ~10lbs per corner in the front and ~12.5lbs per corner in the rear.
Everyone says lighter wheels improve acceleration but I'd like to see some comparative data if anyone has any. I found one mathematical discussion involving rotational inertia and mass which concluded you get 2:1 benefit for tire weight reduction versus sprung weight reduction and 1.6:1 benefit for wheel weight reduction.
