20 piece ACER Racing BLACK Titanium Lug Bolt set for water cooled Porsche911 (996, 997, 991, 991.2 except GT3 which we do sell in a separate listing, 992 etc.) and Porsche Boxster
These are black titanium: we use a Physical Vapor Deposition (PVD) process to achieve the black color, which is a more expensive but much better and more durable method than simply anodizing titanium. PVD is a complex process which vaporizes a number of metals and then binds them on the surface in layers in a heated vacuum. This is the same process used on the beautiful black finish of high end black luxury watches such as Rolex and Panerai watches.
M14x1.5 thread with a 29mm shank length
Porsche OEM Part number is 996 361 203 01 for the steel lug boltand these are a direct replacement but in the highest grade titanium (Grade 5 6AL4V Titanium)
Manufactured from aerospace grade 6AL4V Titanium, these titanium lug bolts will not corrode or rust and offer a significant weight savings over steel lug bolts while giving a very sporty and aggressive look. Titanium is 50% lighter than steel, yet considerably stronger. Titanium is also resistant to the constant heating and cooling cycles that destroy steel.
Rolled threads for superior fatigue resistance.
