Generally speaking, for every additional 100 lbs of "dead" weight, you will lose about 1/10 of a second in a quarter mile time. Again, that's a general figure and will obviously vary from car to car.

Rotating weight, such as that found in wheels, tires, axles, gears, etc., has more of an impact, although I doubt that the wheel/tire combo being discussed here would be noticable at all from a performance perspective...but they do look good!
