Incorrect. Rotating weight has a greater effect. And the farther the weight from the axis, the greater the effect.


Seems real interesting most race teams try to remove body and chassis weight rather than lighter wheels and tires. shruggy If I was going to spend a pocket full of cash to make my street car faster it wouldn't be spent on wheels and tires which wouldn't produce near as much performance as some engine or trans upgrades for the same bucks.
I agree that a swap to lighter wheels is probably not the best "bang for the buck", but the fact remains that reducing rotating weight has a greater effect than reducing an equal amount of fixed weight. And last time I looked, almost every race team used lighter wheels than stock.


Every race team uses lighter chassis, bodies and interiors also.
