unsprung weight

paperboy42190 · 09-29-2013, 05:11 PM

the physics of unsprung weight vs sprung weight gets pretty tricky if you really want to understand it. lots of good articles online to read online though.

but most important thing to know is that lighter is better for performance, but not comfort. heavier wheels usually absorb the bumps more. but its a 370z so Im sure comfort isnt the top of your list. comparing 2 lbs per wheels is almost like splitting hairs though. but if its like 3 lbs per wheel and over, then most likely you'll notice it

I dropped about 9 lbs per wheel in going from the Rays forged aluminum wheels on my sport Z to forged magnesium monoblock wheels from Litespeed Racing. In addition to the increased responsiveness of the steering and suspension, the suspension compliance was also increased. There is less impact shock transmitted through the suspension when I go over bumps and holes in the road, a consequence of impulse and momentum.
