Light weight wheels are a performance part. Heavier wheels or the same weight with a larger diameter will definitely affect all dynamics of driving.
I don't know what size you had from stock, but it looks like the V710 combo for the front rim/tire is 50lbs. You may be around the same weight, but with a larger diameter, which would decrease performance.
