Most wheels and tires aren't that much lighter. I've been doing a lot of research before I buy a new setup for my jalopy. My stock 5 spoke 16 inch Camaro wheels should weigh between 19-20lbs a piece, so we'll call it 80 total. My 255/50/16 ET Street Radials weigh around 29lbs a piece, and my front tires are some cheapo Falken 235/55/16's that are probably around 35lbs each. 208 total lbs in wheels/tires. New combo -
Hoosier Drag Fronts - 11lbs per 22lbs total
Hoosier Drag Radials - 24lbs per 48lbs total
Weld RTS Fronts - 10.2lbs per 20.4lbs total
Weld RTS Rears 15x8 - 13.49lbs per 27lbs total
Total new wheels and tires - 117.4
Which saves 90.6 lbs and should be worth a tenth.
Your other gains would come from less rolling resistance due to the narrower front wheels. As far as rotational vs. static weight, it doesn't really matter. You're only really losing 22lbs from the drive axle wheels and tires. If you wanna multiply that x4 =88lbs it would come up with your tenth that way as well. Removing unsprung weight would make more of a difference than rotational. Hope it helps you make a decision.

Agreed to an extent. A heavier flywheel/clutch is better for certain drag racing applications. Bodies in motion tend to stay in motion. Like I was saying in that last post, you're only taking 22lbs off the drive axle going to dedicated race wheels and tires. And that stupid 4x for anything rotational is just that, stupid. Oh, and I'm all goofed up on cold medicine.
