oh yea unsprung wieght plays into the idea that the bigger the wheel used, diameter, it's harder to get it rotating than a smaller radius. It has to do with angluar interia and moments.

Unsprung weight is simply items that arn't 'sprung', ie everything below the suspension, wheels, hubs, disks, calipers etc..

true, I was just giving a general idea in terms of what to consider when purchasing a new wheel. The idea that a heavier wheel needs more force to move it. So the motor will work harder to move the extra weight when compared to a set of lighter wheels. But, yeah in a race situation ... well here I found this if you guys want to see it.

Rip,

Enkei are a huge after market wheel maker, In New Zealand we have a lot of Japanesse import cars and all the after market parts follow, Enkei are one of the premier wheel manufactures for drag, drift, track and road applications in the import world. If you are really concerned about wheel weight Enkei do a lot of light weight options, the funny thing is you pay more for less (weight).

18" wheels look outstanding on beetles.

To that end, I am going with the recently-purchased wheels below (BBS RX-II 16x6½ et42) but I am opting for 205/55-16 tires as they will have an overall diameter that will be very close to the same as the stock wheels and tires.
