do you guys wanting super light wheels actually track your car? if you dont what is the need. your not gonna be driving your car at the absolute limit where you would be able to tell an actual difference.
How much effect is four pounds per wheel

Don't forget improved braking distances! That's a benefit you will see during daily driving!

my old civic had 9.5 pound forged Fno1R's i ve owned light weight wheels but i was never impressed with how much i could feel from the seat of my pants. i would much rather have good looking wheels than base my decision on the weight of a wheel. i ended up selling the wheels to build my motor which was a much better choice.

yeah but then i would have had to spend more money and for me the gain in performance wasnt worth the amount that i would have to spend.
from my research a set of lightweight 17s will be cheaper than a heavy, pretty set of 18s. Kosei & Motegi the K1s and Traklites are both very well made, and cheap (relative) and not to mention they are practically the lightest wheels within a decent price range (i think SSRs have a lighter wheel for 650 each).
+1
I'm looking at getting a set of 17's SSRs (rockon)
I'm sure I'll notice quite an improvement.
24 lbs (approximate, i think they come out to be 24.1lbs if you really care).
Doubt you will notice a difference between the Kosei K1 TS or the traklites, but you will notice a big difference from stock.
The trick is to get a nice set of tires and lose a few pounds there, too.

See i told you, now you are starting to see the logicSadly I don't think anyone will back this theory up
Yeah you're right. I'm just a little hard headed at times.

something i found about wheel weights. kinda interesting

Light weight is a help, but not at the sacrifice of wheel rigidity. You start cutting out spokes and making thin rims to shave off weight and the rim gets weak. Make sure that lightweight wheel is well designed and quality made.
I had a 97 Probe GT and went from stock 24.5lb wheels to RX-7 FD rims 16lbs each removing 8.5 lbs at each corner and as soon as I pulled out I could tell a huge difference. I will someday drop down to 17" wheels and find a light weight option that I like.
How much do the stock wheels weigh? Never mind. Should have read all before posting.

The test was meant to prove that although most people understand the merit of seeking a lightweight performance wheel, most tend to think that as long as a wheel is rigid or strong enough not to crack or bend, it should be fine. What they point out in this article is that when producing a true, race worthy wheel, reputable manufacturers take into account the degree of rigidity depending on the specifications of the particular racecar. The weight factor is taken into consideration only after the rigidy factor.
Regular High Rigidity Enkei GTC-01 1810 +22: 23.76 lbs.
Specially Lightened Version Enkei GTC-01 1810 +22: 19.8 lbs.
The weight of the lightened version was reduced by 3.96 lbs. Both used Advan A048 (265/35-18 M-Compound). Testing was performed at Ebisu East Circuit using MCRs Z33 driven by Kobayashi and under the same specs (ie., tire pressure, # of laps, etc.)
Regular High Rigidity GTC-01
Best Lap: 1 min. 4.646 seconds
Top Speed: 147.16 km/h @ 17.83 seconds
Specially Lightened GTC-01
Best Lap: 1 min. 5.045 seconds
Top Speed: 141.46 km/h @ 17.74 seconds
A very rough and quick recap: The surface temperature of the tires for the less rigid, specially lightened GTC-01 were higher overall with extensive wear on the outer portion while not enough contact/usage on the inner portion. The high rigidity regular version GTC-01 showed even usage throughout the inner and outer parts of the tire. Also, the low rigidity, lightweight version wheels gave/bent when taking aggressive high speed turns even affecting the height of the car which even led to scraping and alignment problems. Furthermore, the lighter version accelerated much quicker, but ultimately did not lead to faster times. In summary, Kobayashi expressed that a balanced wheel with both rigidity and lightweight characteristics is important, but he never imagined that the effects of rigidity played such a large role.
pretty good recap from og-made.com
