As part of STM’s holiday sales, they had an absolutely insane deal on a set of titanium lug nuts. While these are “meant” for the Evo, they are open ended lug nuts using the 12×1.5 thread pattern – same as the S2000’s studs. The Ti lug nuts are the perfect blend of strength and light weight, usable on the track without fear of losing them like aluminum ones, while still saving some weight. These should be a nice complement to the Volk ZE40’s that are on their way!
Weighing in at just 26 grams (~.9oz). Savings of about 5oz per wheel compared to the Muteki SR48 lug nuts that I had been considering.
