How much weight do chrome rims add ?

Lets just say chrome will add like 6 pounds per wheel. so a 22 Lb wheel will weigh like 28 (CONSERVATIVELY). Ive seen 30+ pound wheels easy. It will jack your car up so much dont even bother trying to race it or drive fast. It wont be much, but its like a bee sting, all the fun will be sucked out of the day. They will be fine if you just wanna cruise or look flashy, but I hate chrome with a passion. My prediction is you will feel it being more sluggish and get pissed off (even though its probably still fast), its all about comparisons, if I went from a geo metro to a boxster with crome 22's Id think it was a bullet.
