They are really light not sure what material but I would guess they are aluminum and yes they are tuner lugs.

would these be the same as the once you posted except open ended because these are made out of billet steel?
NISMO BILLET RACING LUG NUT OEM on eBay!

I've never seen those before.

Although, some dealers pass things off as Nismo at times when they are in fact just generic lugs.

I have these because a friend sold them to me for 75 dollars, he got them for his evo but they were the wrong tread pattern... he is not computer savy and thought he couldnt do anything with them so he gave them to me for cheap..

they are worth retarded money for lugnuts (retail over 200), I was going to sell them but I felt guilty doing so.. http://passwordjdm.com/images/Products/3422L.jpg

$75 for KICS?

Hook me up Chuck :D

Im just using them, shyt why not... im not starving for money but the package said 238, hes like theyre useless just give me 75 bucks, lol...

its nice because they have a unique lock to them...

Chuck = worlds worst friend :icon17:

my friend = worlds most naive friend, lmao...

and on the other hand... I have a set of Muteki plain black open ended lug nuts that I would sell for $30 shipped obo

:icon17:

I will give you $0.50 :tup:

The "Acorn" tappered lugs will not work on our Nismo's, we have to use a flat or "Mag" type seat for our cars and it's impossible to find anything different than what we currently have. :shakes head::ugh2:
