20lb wheels? MB Motorsports Weapons

I am looking at buying the 17x8 MB Motorsports Weapon wheels to replace the stockers on my FD. They claim the wheels are 20lbs each... I am under the impression my stock wheels are around 16 lbs. (I know they are light). I assume that the 17" tires will weigh more than the stock 16" tires as well. Will that much extra unsprung weight have any real consequence to me in track or autocross driving?

Also, if anyone has any opinions or experience with these wheels, please let me know. They seem pretty inexpensive, which I'm hoping does not translate to cheap.

Thanks

They will be a downgrade as far as straightline acceleration AND handling goes. Ride quality will also degrade, because of both the reduced sidewall and because of the increased unsprung weight.

Unless you are just changing them for looks, not a good move.
