Any idea on weight savings over TE37sl? I have 9.5s and 10.5s

like 1.5lbs-2lbs maybe? does that even matter?

id love to see an updated sf challenge or gtv

unsprung weight is very important... lightening the rotational mass can have multiplicative effects on performance, acceleration and effort (and therefore energy) required to turn the vehicle, etc. Losing unsprung weight is very valuable.

:yawn: yah i agree, but which tires are you planning to run? gross weight is most important. unless you're tracking your car 2lbs is not going to make any difference on street.

He does track his car, he is a beginner but quickly learning.
I do agree weight of the wheel plus the tire is important, but every pound comes into account when you are balancing weight & performance.

Hopefully I get out to the track a bit this year, once the MS150 is done I should have more free weekends! >.<

I am running Ventus V12s in 275-45? up front and 305/35 in the rear. I am considering going to a thinner tire (width wise, not sidewall wise) probably Michelin PSS's. Overall weight is what matters, but I am trying to select tires based on what I think will work best... so for the same tires saving a couple pounds might make some difference.

Just not sure if it is a $3000+ difference... lol.

They say 1lb of unsprung weight is roughly equivalent to 5lbs of sprung weight. Every pound counts in a car as heavy as the Z and having less unsprung mass is helpful in acceleration and overall handling.

How much for a set of 19s, 2x9.5 and 2x10.5 in whatever color is cheapest? PM details to me, area code is 77094

:tup:

i see...yah i think some stickier tires (probably go narrower but stickier) and this wheelset will net good gains, given you have improved every aspect of driving your car on track to make a difference, i think.

for street use, 5lbs gross weight difference per corner is where i really notice the difference in braking and overall handling. :)

great advertisement...
