M14 Titanium Bolt

Marque-specific Grade 5 Ti-6Al-4V titanium M14 wheel lug bolts custom-engineered for BMW, Porsche, Mercedes-Benz, Audi, Volkswagen, and Ferrari. Unlike generic one-size-fits-all wheel bolts, our M14 titanium fasteners are precisely matched to manufacturer-specific seat geometries—including 60° conical seats, OEM R13/R14 spherical ball seats, and floating 2-piece ball collars. Delivering over 950 MPa tensile strength, each bolt weighs only 38–75g, shedding up to 40% of critical rotating unsprung weight across all four hubs.

Marque-Specific Seat Configurations

  • BMW (F/G-Chassis & Supra): 60° conical seat, shank lengths 28–50mm, available in M14 × 1.25 and M14 × 1.50 pitch with Torx T70 drive.
  • Porsche (911, Cayman, Boxster, Macan): M14 × 1.5 with authentic 2-piece floating R14 ball seat collar to prevent wheel galling.
  • Mercedes-Benz & AMG: M14 × 1.5 with OEM R14 spherical radius ball seats (27–50mm).
  • Audi & Volkswagen Group: M14 × 1.5 with OEM R13 spherical radius ball seats (28–50mm).
  • Ferrari: Extended 52mm shank M14 × 1.5 wheel lug bolts with 30mm oversized head.

Frequently Asked Questions

Why does Porsche require a floating ball seat collar?

The 2-piece floating collar remains stationary against the aluminum wheel seat while the bolt rotates, eliminating friction galling, wear, and false torque readings during high-load track use.

What is the difference between R13 and R14 ball seats?

R13 indicates a 13mm spherical radius (standard Audi/VW), while R14 indicates a 14mm radius (standard Mercedes/Porsche). Using the wrong radius causes uneven contact pressure and bolt loosening.

What torque should I use for M14 titanium wheel lug bolts?

Torque dry or with light anti-seize strictly to your vehicle manufacturer's specification (typically 130–140 N·m for BMW/Mercedes, 160 N·m for Porsche). Always torque manually.
