Lug Nuts, 2-Piece Floating Collar

Description:   Designed and manufactured by Core4 Motorsports, these lug nuts are engineered to be the best lug nuts on the market for doing the single most important thing a lug nut should do.  Provide accurate and consistent loading on the wheel studs.   Manufactured in the USA from hardened USA alloy steel, the unique floating collar design removes aluminum (wheel nut seat) from the friction equation when turning/tightening the lug nut  Aluminum galls easily and reduces the effective torque and required tension on the stud, and coated lug nuts can wear off over time.By eliminating the detrimental effect of aluminum galling and coating wear on stud preload (see chart), the 2-piece nut design can generate optimal stud tension/preload from the 1st time you tighten them when new, to the 30th+ time, without lubrication anywhere on the threads or nut seat. Note that this is the same design that Porsche uses on their lug bolts.  No other lug nut achieves this, regardless of coating type.
