I can tell you right now, 80 lbs will make a huge difference in a Yaris, and the 120lb driver will make it to the end first.

I agree the lighter car would be faster...not sure that it would be by a large margin though... 80/2300 = .03 or 3%...is 3% that much greater than my less than 1% calculation? ... pretty close...

check out http://www.060calculator.com/

for 106hp and 2300lbs = 9.09 seconds
for 106hp and 2380lbs = 9.33 seconds

1-(9.09/9.33) = .025 or 2.5%

Is it safe to say that lighter rims will increase accelleration by less than 3%? Is 3% a huge difference? or is 3% a small difference? I could make strong arguments either way ...
