The Project Kics R40/R40 Iconix lugnuts are highly considered as some of the best hardware to pair with your authentic Japanese wheels. These patented locking lugnuts feature a floating seat, which allows the cone-shaped portion to "spin freely" as the lugnuts are being torqued down. As this happens, this reduces the likelihood of scratching the seat pocket of your wheel.
The R40 Iconix lugnuts come in Black, Neochrome, and Classical (R40 only, no Iconix) They come in locking configurations (16+4pc), or without a lock (20pc).
