my sponsor just handed me some forged aluminum lugs to try out. they told me that it's a limited edition gunmetal color. i was already running forged lugs, but these look much better so i slapped them on.
i looked in the threaded portion.. they utilized a lot of the lug.. the threaded portion looks to be a good 1.5" in length. i have extended studs so the lugs will have a better hold on the studs (a definite must when you're running race tires pulling over 1g lateral).
pics don't do much justice.. i have one of the first gen digicams, so the color accuracy sucks.
