Default quarter mile times w/ wheel weight savings?

The only reason I would purchase aftermarket wheels is if they would provide a reasonable amount of performance increase.

Supposed you got a lighter 16 inch wheel. Let's say you save 6 pounds / wheel vs the stock rims. Same tires. How much time might you save in the quarter mile? IAre we talking 0.2 seconds or 0.000000001 seconds?

Thanks!

24 total pounds won't make any difference in 1/4 mile times! You'll lose more weight running the 1/4 mile with a low tank of gas! If you put smaller diameter wheels with low profile tires on the rear 15inch will fit (14 inch might clear the rotors?) you essentially change the gear ratio and will improve the 1/4 mile time but it will look extra dorky so I would only do it at the drag strip.

hygiene...dont forget, thats 24LBS of rotating mass...which if i remember correctly equates to 240 LBS of standing weight!!! That can make a huge difference! Every 10 LBS of rotating weight is equivalent to roughly 100 LBS of standing weight!@!

It's true, but I think it's closer to 10 lbs. rotating mass = about 40 lbs. stationary mass... still pretty significant. Also, the reduction in unsprung weight will improve handling.

I never heard that but I guess there could be truth to it. I still don't think slightly lighter wheels will make a significant difference in 1/4 mile E.T. If you're not changing wheels for looks I think that amount of money could be spent elsewhere that would have a more dramatic effect on performance.

Is there a rule of thumb for our car that says for every 100lbs you shave off, you will go XXX tenths of a second faster in the quarter mile?

Maybe we can estimate it by posting some numbers of known cars with weight savings mods.

Also, a definitive answer on the wheelsprung weight would be awesome. Is it 4lbs or 10pbs for every wheel pound or something else?
