Wheels are not just unsprung weight, they are mass that needs to be rotated as well. The driven wheels feel the effect of the mass.

I remember some time back reading a tuning magazine where they had some modded honda on the dyno. Car put down about 150whp. Then they put on bigger heavier wheels/tires (same rolling circumference) and the car lost 8-10 whp.......

Remember, bigger brakes also need to be accelerated, it is not just wheels...

Cheers
