I removed a front and rear wheel/ tire off of my S2K today for the sole purpose of weighing them and comparing to the stock setup. I weighed the stock tire and rim for the front and rear first. These tires have less than 500 miles on them and look like new. The HREs I weighed are 545 w/ anodized centers and polished outerlips. The front is 8.5x18" wearing a 245/35/18 P-Zero w/ the Smartire sensor installed(doesn't weigh enough to worry about IMO). The rear HRE is 10.5x18" wearing a 285/30/18 P-Zero w/ the Smartire sensor installed. Here are the results:

OEM front wheel/tire= 41 lbs.
OEM rear wheel/tire= 45 lbs.
_______________________
total of (4) -2 ea. = 172 lbs.


HRE front wheel/tire= 50.5 lbs.
HRE rear wheel/tire= 58 lbs.

_______________________
total of (4) -2 ea. = 217 lbs.


That's a total of 45 extra lbs. of unsprung weight. Even though this is quite a bit more than I thought the difference was; I have no plans of trading my HREs in. I figure that with my future FI mods I will need the extra traction. Also in grip, looks, and craftsmanship; IMO, the HREs can't be beat.

 

doesnt' seem that much of a difference if you think about it - you DO have lots more meat under the corners! especially w/10.5 inches in the rear! wow! just incredible man. I love that setup.

 

that sounds impressive. can you show some pictures or links to what type of rims you have. i can not picture it in my mind. thanks

 

when are you going to lower that 4x4?

 

those rims should weigh about 24-25lbs compared to 18-19 lbs for oem rims.

 

I'm thinking more like 20-21lbs vs. 16-17lbs w/ tires accounting easily for the balance.

 

unfortunately they're 25lbs stated by HRE themselves.

 

just make sure you dont do hard launches, you might snap your axles.
too much grip

 

what offset are the front HRE's and how much are u lowered, and do the ever rub?

i just mounted 225/45 17 on mugen MF10, i believe 7.5" width with 52mm offset, after 215's were replaced.
i'm lowered 1" in front. i've gotten a couple rubs on moderate hard compressions.

any thoughts? has anyone flattened the inner fender lip on their s2k, or know if this is worthwhile?
