101...
I spent literally days/nights researching lug-nuts years ago, so I'll chime in.
*
Blox forged Titanium lug-nuts go for (16) ~$240/shipped or (20) ~$300/shipped.
Muteki Titanium finish lug-nuts go for (20 w/ adapter-key) ~$45/shipped
Muteki "Neon" Titanium finish (heat-treated) aluminum lug-nuts go for (20 w/ adapter-key) ~$105/shipped
Hyperlug Titanium "Gold" finish aluminum lug-nuts go for (20) ~$65/shipped
5Zigen Titanium "Silver" finish aluminum lug-nuts go for (20) for ~$120/shipped
* Motorklasse Titanium lug-nuts go for (20) ~$370/shipped [
kwkim -> former NSX Prime sponsor]
* T1R Titanium lug-nuts go for (20) ~$500/shipped
* GT Design Titanium lug-nuts (pictured in this thread by the O.P.) go for (20) ~$500/shipped
* = real forged or machined Titanium-alloy, not a Titanium-finish and/or heat-treated over polished chrome/stainless-steel
Weights of the lug-nuts go as follows (generally):
Magnesium-alloy < Aluminum-alloy = Titanium-alloy < Steel-alloy
Strength of the lug-nuts go as follows (generally):
Titanium-alloy > Steel-alloy > Aluminum-alloy > Magnesium-alloy
The beveled-edge ("roundish" sublimated-tip) keeps tire-irons & air-tools from chipping/scratching/marring the end of the lug-nut, IMHO it's necessary for an aesthetically appealing lug-nut unless the user doesn't care about blemishes on the appearance (ie. track-guru's, etc'). . .
Also, texturing/grooving that beveled-edge is generally recommended for ease of removal/installation (tactile-grip) for those who swap/replace wheels more often than not. . .
BTW: for the cost, durability, marginal weight-savings, long-term integrity, and seizing ("
galling"), they aren't worth it. From a pro's & con's stand-point, they don't make sense. Magnesium-alloy is lighter, aluminum-alloy is the same weight & cheaper, steel-alloy can be treated to have same appearance/finish, blah-bla-bla...
But, for a show-car... why not! Go for it. . .
Anywayz...
G'luck w/ the group-buy! Produce the ones pictured in the 1st post (beveled-edge) & you'll win; if w/o the beveled-edge, why bother as
Blox already makes it at the price-point you're offering (~$250'ish), I'm sure a direct-vendor/wholesaler can get them in bulk for even less...
